SAFETY INSTRUCTIONS….cont
STORE THE WELDER SAFELY WHEN NOT IN USE: The welder should be stored in a dry
location and disconnected from the mains supply, and out of the reach of children.
USE SAFETY CLOTHING / EQUIPMENT: Use a CE approved welding mask at all times
with the correct shade of filter lens. A fume extractor should be used particularly where
there is little or no ventilation.
PROTECT YOURSELF FROM ELECTRIC SHOCK: When working with the welder, avoid con-
tact with any earthed items (e.g. pipes, radiators, hobs and refrigerators, etc.). It is ad-
visable wherever possible to use an RCD (residual current device) at the mains socket.
STAY ALERT: Always watch what you are doing and use common sense. Do not oper-
ate the welder when you are tired or under the influence of alcohol or drugs.
DISCONNECT THE WELDER FROM THE MAINS SUPPLY: When not in use and before ser-
vicing.
AVOID UNINTENTIONAL STRIKING: Make sure the switch is in the OFF position before
connecting the welder to the mains supply.
NEVER LEAVE THE WELDER CONNECTED WHILST UNATTENDED: Turn the welder off and
disconnect it from the mains supply between jobs. Do not leave the welder connect-
ed to the mains supply if no more welding is to be done.
DO NOT ABUSE THE MAINS LEAD: Never attempt to move the welder by the mains lead
or pull it to remove the plug from the mains socket. Keep the mains lead away from
heat, oil and sharp edges. If the mains lead is damaged, it must be replaced by the
manufacturer or its service agent or a similarly qualified person in order to avoid un-
wanted hazards. All extension cables must be checked at regular intervals and re-
placed if damaged.
CHECK FOR DAMAGED PARTS: Before every use of the welder, any damage found
should be carefully checked to determine that it will operate correctly, safely and per-
form its intended function. Any damaged, split or missing parts that may affect its op-
eration should be correctly repaired or replaced by an authorised service centre un-
less otherwise indicated in this instruction manual.
KEEP ALL PANELS IN PLACE: Never operate the welder with the panels removed, this is
extremely dangerous.
MAINTAIN THE WELDER WITH CARE: Keep the earth clamp, mig tip & shroud clean for
the best and safest performance.
USE ONLY RECOMMENDED ACCESSORIES: Consult this user manual, your distributor or
SIP directly for recommended accessories. Follow the instructions that accompany the
accessories. The use of improper accessories may cause hazards and will invalidate
any warranty you may have.
SECURE THE WORKPIECE: Always use welding clamps to secure the workpiece. This
frees up both hands to operate the welder correctly.
DO NOT OVERREACH: Keep proper footing and balance at all times.
USE THE RIGHT TOOL: Do not use the welder to do a job for which it was not designed.
DO NOT OPERATE THE WELDER IN EXPLOSIVE ATMOSPHERES: Do not use the welder in
the presence of flammable liquids, gases, dust or other combustible sources. Welding
will create sparks which can ignite the dust or fumes.

6
SAFETY INSTRUCTIONS….cont
DO NOT EXPOSE THE WELDER TO RAIN OR USE IT IN WET CONDITIONS: Water entering
the welder will greatly increase the risk of electric shock and equipment damage.
HAVE YOUR WELDER REPAIRED BY A QUALIFIED PERSON: The welder is in accordance
with the relevant safety requirements. Repairs should only be carried out by qualified
persons using original spare parts, otherwise this may result in considerable danger to
the user.
Stop operation immediately if you notice anything abnormal.
Always disconnect the plug from the mains supply before cleaning or servicing etc.
Be alert at all times, especially during repetitive, monotonous operations; Don't be
lulled into a false sense of security.
Use of improper accessories may cause damage to the inverter welder and sur-
rounding area as well as increasing the risk of injury.
Do not modify the inverter welder to do tasks other than those intended.
To avoid injury, the workpiece should never be held with bare hands; The workpiece
will become hot during normal welding operations, and stay hot for a period after
the weld is complete.
Appropriate personal protective equipment must be worn and must be designed to
protect against all hazards created. Severe permanent injury can result from using
inappropriate or insufficient protective equipment - Eyes in particular are at risk.
The work should be clamped firmly whilst welding, If its loose it could result in person-
al injury or damage to the machine or item that is being welded.
Do not attempt any repairs to the welder unless you are a competent electrician or
engineer.
Ensure that the machine is connected to the correct supply voltage and protected
by a fuse or circuit breaker of the recommend rating.
Never allow the earth clamp and electrode holder to come into contact with each
other.
Understand the operating environment; Before each use the operator should as-
sess, understand and where possible reduce the specific risks and dangers associ-
ated with the operating environment. Bystanders should also be made aware of
any risks associated with the operating environment.
Electromagnetic fields can interfere with various electrical and electronic devices
such as pacemakers; Consult your doctor before using any electric welder or cut-
ting device.
Keep people with pacemakers away from your welding area when welding.
Do not wrap cable around your body while welding.
If the welder is to be used on business premises - ensure that all local and national
regulations are followed concerning the use of portable electrical appliances at
work.

SAFETY INSTRUCTIONS….cont
Electric welders have the potential to cause a shock that could lead to injury or death.
Touching electrically ‘hot’ parts can cause fatal shocks and severe burns; While weld-
ing, all metal components connected to the welder are electrically ‘hot’.
Keep your body and clothing dry. Never work in a damp area without ade-
quate insulation against electrical shock, stay on a dry duck board, or rubber
mat when dampness or sweat can not be avoided. Sweat, sea water or mois-
ture between the body and an electrically ’hot’ part or grounded metal reduces
the body surfaces electrical resistance enabling dangerous and possibly lethal
currents to flow through the body.
Never allow live metal parts to touch bare skin or any wet clothing, be sure
welding gloves are dry.
Before welding, check for continuity; Be sure the earth clamp is connected to
the workpiece as close to the welding areas as possible. Grounds connected to
building frame work or other remote locations from the welding area reduce
efficiency and increase the potential electric shock hazard. Avoid the possibility
of the welding current passing through lifting chains, crane cables or other elec-
tric paths.
Frequently inspect leads for wear, splits, cracks and any other damage. Imme-
diately replace those with worn or damaged insulation to avoid a possibly lethal
shock from bare leads.
During normal operation, the heat and sparks created during the welding process
have the potential to ignite flammable liquids, gases or other combustible material.
All inflammable materials must be removed from the area.
Have a suitable fire extinguisher available close by.
Causes of fire and explosion include; combustibles reached by the arc, flame,
flying sparks, hot slag or heated material, misuse of compressed gases and
cylinders and short circuits.
Flying sparks or falling slag can pass through cracks along pipes, through win-
dows or doors and through walls or floor openings and out of sight of the opera-
tor; Sparks and slag can fly up-to 10 metres.
Keep equipment clean and operable; Free of oil, grease and of metallic parti-
cles (in electrical parts) that can cause short circuits.
If combustibles are in the area. Do not weld , move the work if practical to an
area free of combustibles, avoid paint spray rooms, dip tanks, storage areas
and ventilators. If the work can not be moved, then move the combustibles at

least 10 metres away and out of the reach of sparks and heat or protect
against ignition with suitable and snug fitting, fire resistant covers or shields.
Walls touching combustibles on opposite sides should not be welded on, walls,
ceilings and the floor near the work area should be protected by heat resistant
covers or shields.
Openings (concealed or visible) in floors or walls within 10 metres may expose
combustibles to sparks.
Combustibles adjacent to walls, ceilings, roofs or metal partitions can be ignit-
ed by radiant or conducted heat.
After the work is done, check that the area is free of sparks, glowing embers and
flames.
An empty container that has held combustibles, or that can produce flamma-
ble or toxic vapours when heated, must never be welded, unless the container
has first been cleaned. Consult HSE INDG214, HSG250 and CS15. HSE docu-
ment CS15 includes information on cleaning by thorough steam or solvent/
caustic cleaning followed by purging and inserting with nitrogen, carbon diox-
ide or water filling just below working level.
A container with unknown contents should be treated as if it contained combus-
tibles (see previous paragraph), Do not depend on sense of smell or sight to
determine if it is safe to weld.
Hollow items must be vented before welding as they can explode.
Explosive atmosphere; Never weld when the air may contain flammable dust,
gas or liquid vapours (such as petrol).
SAFETY INSTRUCTIONS….cont
The welding arc produces ultraviolet (UV) and infrared (IR) rays as well as extreme tem-
peratures that can cause injury to your eyes and skin. Do not look at the welding arc
without proper eye protection.
The electric welding arc must not be observed with the naked eye. Always use a
welding mask; Ensure the welding mask is fitted with the correct shade of filter
lens for the welding current level, and covers the entire face from neck to the
top of the head.
Welding gauntlet gloves should be worn to protect the hands from burns, non-
synthetic overalls with buttons at the neck and wrist, or similar clothing should be
worn. Greasy overalls should not be worn. Wear suitable protective footwear.
Always wear correctly rated protective clothing which covers all areas of the
body; The operator should not weld with any bare skin showing to reduce the
chance of burns etc.
Avoid oily or greasy clothing, a spark may ignite them.
Hot metal such as electrode stubs and workpieces should never be handled

SAFETY INSTRUCTIONS….cont
Ventilation must be adequate to remove the smoke and fumes during welding
(see the relevant safety standard for acceptable levels).
Toxic gases may be given off when welding, especially if zinc or cadmium
coated materials are involved, welding should be carried out in a well ventilat-
ed area and the operator should always be alert to fume build-up.
Areas with little or no ventilation should always use a fume extractor.
Vapours of chlorinated solvents can form the toxic gas phosgene when ex-
posed to U.V radiation from an electric arc. All solvents, degreasers and poten-
tial sources of these vapours must be removed from the arc area.
Severe discomfort, illness or death can result from fumes, vapours, heat, oxygen
enrichment or depletion that welding (or cutting) may produce. This will be pre-
vented by adequate ventilation or using a fume extractor. NEVER ventilate with
oxygen.
Lead, cadmium, zinc, mercury, beryllium bearing and similar materials when
welded may produce harmful concentrations of toxic fumes. Adequate ventila-
tion must be provided for every person in the area. The operator should also
wear an air supplied respirator, for beryllium both must be used.
Metals coated with or containing materials that emit toxic fumes should not be
heated unless coating is removed from the work surface. The area should be
well ventilated or the operator should wear an air supplied respirator.
Work in a confined space only while it is being ventilated and if necessary whilst
wearing an air supplied respirator.
Gas leaks in a confined space should be avoided, leaking gas in large quanti-
ties can change oxygen concentration dangerously. DO NOT bring gas cylin-
ders into a confined space.
Leaving a confined space you must shut off the gas supply at the source to
prevent possible accumulation of gases in the space if down stream valves are
left open. Check to be sure that the space is safe before re-entering it.
without gloves.
First aid facilities and a qualified first aid person should be available for each
shift unless medical facilities are close by for immediate treatment of flash burns
to the eyes and skin.
Flammable hair products should not be used by persons intending to weld.
Warn bystanders not to watch the arc and not to expose themselves to the
welding arc rays or to hot metal.
Keep children away whilst welding, they may not be aware that looking at an
arc can cause serious eye damage.
Protect other nearby personnel from arc rays and hot sparks with a suitable non-
flammable partition.
VENTILATION

10
SAFETY INSTRUCTIONS….cont
Some metals and metal composites have the potential to be highly
toxic; always wear a face mask .
When using the welder always ensure the operator as well as those
in the area use a welding mask with the correct shade filter lens.
CAUTION: The warnings and cautions mentioned in this user manual can not
cover all possible conditions and situations that may occur. It must be under-
stood by the operator that common sense and caution are factors which can-
not be built into this product, but must be applied.
Vapours from chlorinated solvents can be decomposed by the heat of the arc
(or flame) to form phosgene a highly toxic gas and other lung and eye-irritating
products. The ultra violet (radiant) energy of the arc can also decompose tri-
chloroethylene and perchlorethylene vapours to form phosgene. DO NOT
WELD or cut where solvent vapours can be drawn into the welding atmosphere,
or where the radiant energy can penetrate to atmospheres containing even
minute amounts of trichloroethylene or perchlorethylene.

ELECTRICAL CONNECTION
WARNING! It is the responsibility of the owner and the operator to read, understand
and comply with the following:
You must check all electrical products, before use, to ensure that they are safe.
You must inspect power cables, plugs, sockets and any other connectors for wear or
damage.
You must ensure that the risk of electric shock is minimised by the installation of appro-
priate safety devices; A residual current circuit Breaker (RCCB) should be incorporated
in the main distribution board. We also recommend that a residual current device
(RCD) is used. It is particularly important to use an RCD with portable products that are
plugged into a supply which is not protected by an RCCB. If in any doubt consult a
qualified electrician.
Connecting to the power supply:
The HG3000S welder is supplied without a plug fitted, it must not be connected to a
standard 13A supply; Consult the technical specification table (page 13) for the re-
quired rating, if in doubt contact a qualified electrician. Before using the welder, in-
spect all the leads and plugs to ensure that none are damaged. If any damage is
visible have the welder inspected / repaired by a suitably qualified person.
The wires for the plug are coloured in the following way:
Yellow / green Earth
Blue Neutral
Brown Live
As the colours of the wires may not correspond with the markings in your plug, pro-
ceed as follows:
The wire which is coloured brown, must be connected to the terminal, which is
marked L or coloured red (or brown).
The wire which is coloured blue, must be connected to the terminal marked with N or
coloured black (or blue).
The wire which is coloured yellow / green should be connected to the terminal which
is coloured the same or marked with this symbol
Always secure the wires in the plug terminal carefully and tightly. Secure the cable in
the cord grip carefully.

12
Warning: Never connect live or neutral wires to the earth terminal of the
plug. Only fit an approved plug with the correct rated fuse. If in doubt
consult a qualified electrician.
ELECTRICAL CONNECTION….cont
This SIP mig welder is covered by a 24 month parts and labour warranty covering fail-
ure due to manufacturers defects. This does not cover failure due to misuse or operat-
ing the mig welder outside the scope of this manual - any claims deemed to be out-
side the scope of the warranty may be subject to charges Including, but not limited to

OPERATING INSTRUCTIONS….cont
Connect the electrode lead (+) and earth lead (-) to the appropriate terminal
on the front of the welder.
Fit the required electrode securely into the electrode holder.
Switch the welder on.
Select the ARC welding mode on the welding selector switch (15).
Set the amperage control to match your electrode size.
Place a face mask over your face.
Bring the electrode into contact with the workpiece using a light tapping action
and withdrawing to create a gap of 1.5 mm –3.0 mm.
When the arc is created, proceed steadily in one direction keeping the gap
between the electrode and the workpiece constant.
When the weld is complete simply remove the electrode from the workpiece.
Remove any excess weld / slag with a wire brush / hammer (not supplied).
WELDING - ARC
Caution: Ensure all protective equipment is worn and bystanders are not in
the vicinity.
Note: In order to arc (MMA) weld with the welder, you will need to purchase
an electrode holder and lead - SIP part number 10230.
Caution: Be aware that the electrode is now live, simply touching any part
of the workpiece will create a spark.

OPERATING INSTRUCTIONS….cont
There are no hard and fast rules by which a particular gauge of electrode is selected,
usually this is determined by the type of welding required and the thickness of the
workpiece e.g. a butt weld in 1.5mm (1/16”) sheet metal can be done by a 1.6mm or
2.0mm electrode, the difference being that the 2.0mm electrode will do the job
more quickly.
The table below gives a guide as to which electrode is most suitable according to the
material thickness. This table is only a guide, and values given are an indication only.
These welding current values are for the E6013 electrodes, for other types of electrode
consult their data sheet.
Electrode Size mm Material Thickness mm Welding Current (A)
1.6 1 - 1.6 25 - 40
2.0 1.6 - 2.6 40 - 70
2.5 2.6 - 4.0 60 - 100
3.25 3.0 - 5.0 80 - 130
4.0 5.0 - 7.0 130 - 170
Note: The above is a guide only; always try a short weld test at the setting
selected. It is normal to make minor adjustments to achieve the required
weld.
The welder should be set to a specific amperage to match the electrode size (see
above table).
The amperage control is operated by rotating the Arc welding output control knob
(16) on the front of the welder; Rotate the knob clockwise to increase the amperage
and anti-clockwise to reduce the amperage. Once the amperage control is set do a
short weld and check for correct fusion.
AMPERAGE CONTROL
Clean the area to be welded, and the earthing point of all rust, paint and con-
taminants etc.
Place the earth clamp on to a cleaned area of the workpiece.
Connect the welder to the electrical supply but do not switch on.

OPERATING INSTRUCTIONS….cont
Clean the area to be welded, and the earthing point of all rust, paint and con-
taminants etc.
Place the earth clamp on to the cleaned area of the workpiece.
Connect the welder to the electrical supply.
Note: In order to use gas you will need to purchase gas, gas hose fitting
and a gas regulator suitable for the type of welding required.
Use the main On/Off switch (21) to turn the welder on.
Select the Mig welding mode on the welding selector switch (15).
Set the welding output (11), Wire Speed (8), burn back (4), inductance (3), and
2T/4T function (9) as required by adjusting the appropriate controls.
Press the torch trigger and feed the wire out a little.
Cut the wire about 3mm from the MIG contact tip.
Connect the gas pipe to the gas regulator (not supplied) (where applicable).
Turn the gas on (where applicable).
Place a welding mask/shield (not supplied) over your face.
Position the torch so the Mig tip is around 6mm from the point where the weld-
ing is to commence.
Press the torch trigger (depending on 2T/4T setting) and move the torch slowly in
the chosen direction.
Once the weld is complete, release the torch trigger (depending on the 2T/4T
setting).
Note: If the welder has a humming sound and a blob forms on the tip end, then you have insufficient wire
feed speed and it should be increased. If the welder has an erratic sound and the torch feels that the wire
is hitting against the work, then you have the wire feed speed to high and it should be reduced, when the
wire feed speed is correct you should get a steady crackling sound.
Note: For future reference make a note of the voltage and wire speed set-
ting for the material that has been welded.

nents might become too high due to over use; The internal thermal protector will then
prevent the unit from operating. Its Intervention is Indicated by the alarm light on the
front panel, If this happens leave the machine switched on with the fan running and
allow It to cool down. The thermal protector will re-set automatically after a short peri-
od of time when the components have cooled you will be able to restart welding.

OPERATING INSTRUCTIONS….cont
Feed the wire through the inlet guide spring, over the wire feed rollers and
through the guide tubes (you may need to straighten the first 50mm or so of
wire if it doesn't fit in to the guide tube easily).
Lower the tension arms and ensure the wire sits in the groove of the wire feed
rollers.
Push the pressure adjustment knob back over the tension arms.
Screw the pressure adjustment knob down, but not too tight as it will crush the
wire.
Plug the welder in to the mains supply and turn it on.
Lay the mig torch out as straight as possible.
Press and hold the “inching” button until the wire comes out from the end of the
torch.
Release the “inching” button.
Re-fit the mig tip and shroud.

Caution: Ensure that no body parts are in line with the torch when the wire
comes out as the wire could be sharp.
Note: Be sure the wire feeds from the bottom of the spool and not from the
top.
These units can be set to deliver different output currents at a duty cycle that is written
as a percentage on page 13. This percentage represents the welding time in a 10
minute cycle, e.g. 60% means that the welding time is 6 minutes and the rest time is
4 minutes. If a unit is used beyond its duty cycle the temperatures of some compo-

Before feeding the wire, you should ensure that the correct wire feed rollers are fitted.
To check / change the roller:
Pull the pressure adjustment knobs on the wire feed motor forwards so it takes
the pressure from the tension arms.
Loosen and remove the roller retaining screws and spacer.
The size of the roller should be clearly marked on the side.
Change as required by simply pulling the roller from the roller shaft.
To refit the rollers ensure that the 2 roller drive pins line up with the 2 holes on the
roller.
Refit and tighten the spacer and retaining screw to secure the roller in place.
The wire can now be fed through the torch:
Remove the shroud from the torch by rotating the shroud clockwise and pulling
at the same time.
Unscrew and remove the Mig contact tip.
Pull the pressure adjustment knobs forwards so it takes the pressure from the ten-
sion arms.
Remove the free end of the Mig wire from the side of the wire spool, trim off the
distorted end of the wire with a pair of wire cutters; Hold the wire carefully as it
will try to unwind from the spool.
