The device and packaging material are not toys! Children must not be allowed to play with the machine and its
accessories. Plastic parts and packaging are choking risks for children.
• Open the packaging and remove the welder carefully.
• Check that the delivery is complete.
• If possible, store the packaging until the warranty period has expired.
PERSONAL PROTECTIVE EQUIPMENT (PPE)
GLOVES AND PROTECTIVE CLOTHING
Use protective gloves and re resistant protective clothing when welding.
Avoid exposing skin to ultraviolet rays produced by the arc.
WELDING HELMET
Under no circumstances should the welder be operated unless the operator is wearing a
welding helmet to protect the eyes and face. There is serious risk of eye damage if a helmet is
not used. The sparks and metal projectiles can cause serious damage to the eyes and face.
The light radiation produced by the arc can cause damage to eyesight, and burns to skin.
Never remove the welding helmet whilst welding.
SAFETY GLASSES
After welding use appropriate safety glasses when brushing, chipping or grinding the slag from
the weld.
OTHER PERSONS
Ensure that other persons are screened from the welding arc and are at least 15 metres away
from the work piece. Always ensure that the welding arc is screened from onlookers, or people
just passing by. Use screens if necessary, or non-reecting welding curtain. Do not let children
or animals have access to the welding equipment or to the work area.
SWITCHING OFF
When the operator has nished welding they must switch the welder off.
DO NOT put the electrode holder down with the welder switched ON.
When leaving the welder unattended, move the ON/OFF switch to the OFF position and
disconnect the welder from the electrical mains supply.
Do not leave hot material unattended after welding.
FUMES &GASES ARE DANGEROUS
Smoke and gas generated whilst welding or cutting can be harmful to people’s health. Welding
produces fumes and gases. Breathing these fumes and gases can be hazardous to your health.
• Do not breathe the smoke and gas generated whilst welding or cutting, keep your head out of
the fumes
• Keep the working area well ventilated, use fume extraction or ventilation to remove welding
fumes and gases.
• In conned or heavy fume environments always wear an approved air-supplied respirator.
Welding fumes and gases can displace air and lower the oxygen level causing injury or
death. Be sure the breathing air is safe.
• Do not weld in locations near de-greasing, cleaning, or spraying operations.
The heat and rays of the arc can react with vapours to form highly toxic and irritating gases.
• Materials such as galvanized, lead, or cadmium plated steel, containing elements that can
give off toxic fumes when welded. Do not weld these materials unless the area is very well
ventilated, and or wearing an air supplied respirator.
WARNING

6 7
Keep the welding cables, earth clamp and electrode holder in good condition. Failure to do this can result in
poor welding quality, which could be dangerous in structural situations.
Prior to use, check for breakage of parts and any other conditions that may affect operation of the welder.
Any part of the welder that is damaged should be carefully checked to determine whether it will perform its
intended function whilst being safe for the operator. Any part that is damaged should be properly repaired,
or replaced by an authorised service centre.
IMPROPER USE
It is hazardous to use the welding machine for any work other than that for which it was designed e.g. do not
use welder for thawing pipes.
HANDLING
Ensure the handle is correctly tted. As welding machines can be heavy, always use safe lifting practices when
lifting.
POSITION AND HANDLING
To reduce risk of the machine being unstable / danger of overturning, position the welding machine on a
horizontal surface that is able to support the machine weight. Operators MUST NOT BE ALLOWED to weld in
raised positions unless safety platforms are used.
WARNING
The user of this welder is responsible for their own safety and the safety of others. It is important to read,
understand and respect the contents of this user guide. When using this welder, basic safety precautions,
including those in the following sections must be followed to reduce the risk of re, electric shock and personal
injury. Ensure that you have read and understood all of these instructions before using this welder.
Persons who are not familiar with this user guide should not use this welder. Keep this booklet in a safe place
for future reference.
TRAINING
The operator should be properly trained to use the welding machine safely and should be informed about the
risks relating to arc welding procedures. This user guide does not attempt to cover welding technique. Training
should be sought from qualied / experienced personnel on this aspect, especially for any welds requiring a high
level of integrity for safety.
SERIOUS FIRE RISK
The welding process produces sparks, droplets of fused metal, metal projectiles and fumes.
This constitutes a serious re risk. Ensure that the area in which welding will be undertaken is clear of all
inammable materials. It is also advisable to have a re extinguisher, and a welding blanket on hand to protect
work surfaces.
MACHINE CARE / SAFETY
SAFETY INSTRUCTIONS

8 9
Ensure a clear, well lit work area with unrestricted movement for the operator.
The work area should be well ventilated, as welding emits fumes which can be dangerous.
Always maintain easy access to the ON/OFF switch of the welder, and the electrical mains supply.
Do not expose the welder to rain and do not operate in damp or wet locations
WORK AREA
Where welding must be undertaken in environments with increased risk of electric shock, conned spaces or in
the presence of ammable or explosive materials, it is important that the environment be evaluated in advance
by an “expert supervisor”. It is also recommended that welding in these circumstances be carried out in the
presence of persons trained to intervene in emergencies.
AVOID ELECTRICAL CONTACT
Use adequate electrical insulation with regard to the electrode, the work piece and any accessible earthed metal
parts in the vicinity. Avoid direct contact with the welding circuit. The no load voltage between the earth clamp
and the electrode can be dangerous under certain circumstances.
Note: For additional protection from electric shock. It is recommended that this welder be used in conjunction
with a residual current device (RCD) with rated residual current of 30MA or less.
In general the use of extension leads should be avoided. If used however, ensure that the extension lead is
used with the welder is of a suitable current rating and heavy duty in nature that MUST have an earth
connection. If using the welder outdoors, ensure that the extension lead is suitable for outdoor use. Always keep
extension leads away from the welding zone, moisture and any hot materials.
WELDING SURFACES
Do not weld containers or pipes that hold, or have held, ammable liquids or combustible gases or pressure.
Do not weld on coated, painted or varnished surfaces as the coatings may ignite, or can give off dangerous
fumes.
WORK PIECE
When welding, the work piece will remain at high temperature for a relatively long period. The operator must not
touch the weld or the work piece unless wearing welding gloves. Always use pliers or tongs. Never touch the
welded material with bare hands until it has completely cooled.
VOLTAGE BETWEEN ELECTRODE HOLDERS OR TORCHES
Working with more than one welding machine on a single work piece, or on work pieces that are connected,
may generate a dangerous accumulation of no-load voltage between two different electrode holders or torches,
the value of which may reach double the allowed limit.

8 9
WARNING
Before starting any cleaning, or maintenance procedures on the welding machine, make sure that it is switched
OFF and disconnected from the mains supply.
There are no user serviceable parts inside the welder. Refer to a qualied service personnel if any internal
maintenance is required. After use, wipe the welder down with a clean soft dry cloth.
Regular inspection of the supply cord is required and if damaged is suspected, it must be immediately replaced
by the manufacturer, its service agent or similarly qualied persons in order to avoid a hazard
STORAGE/ TRANSPORT
Store the welder and accessories out of children’s reach in a dry place. If possible store the welder in the
original packaging. The appliance must unconditionally be secured against falling or rolling over during
transport.
DISPOSING OF THE PACKAGING
Recycling packaging reduces the need for landll and raw materials. Reuse of the recycled material
decreases pollution in the environment. Please recycle packaging where facilities exist. Check with your local
council authority for recycling advice.
DISPOSING OF THE WELDER
Welders that are no longer usable should not be disposed of with household waste but in an environmentally
friendly way. Please recycle where facilities exist. Check with your local council authority for recycling advice.
MAINTENANCE
DISPOSAL
GAS BOTTLE
ATTENTION! - CHECK FOR GAS LEAKS
At initial set up and at regular intervals we recommend to check for gas leakage
Recommended procedure is as follows:
1. Connect the regulator and gas hose assembly and tighten all connectors and clamps.
2. Slowly open the cylinder valve.
3. Set the ow rate on the regulator to approximately 10-15 l/min.
4. Close the cylinder valve and pay attention to the needle indicator of the contents pressure gauge on
the regulator, if the needle drops away towards zero there is a gas leak. Sometimes a gas leak can be
slow and to identify it will require leaving the gas pressure in the regulator and line for an extended time
period. In this situation it is recommended to open the cylinder valve, set the ow rate to 8-10 l/min,
close the cylinder valve and check after a minimum of 15 minutes. Ensuring adequate ventilation for
small spaces.
5. If there is a gas loss then check all connectors and clamps for leakage by brushing or spraying with
soapy water, bubbles will appear at the leakage point.
6. Tighten clamps or ttings to eliminate gas leakage.
IMPORTANT! - We strongly recommend that you check for gas leakage prior to operation of your
machine. We recommend that you close the cylinder valve when the machine is not in use.
BOSSWELD, authorised representatives or agents of BOSSWELD will not be liable or responsible for
the loss of any gas.

DUTY CYCLE
Special note:
If this welders duty cycle is exceeded the welder will enter “thermal overload” which will automatically
stop the welding output in order to protect, both the user and the welder. You will know the welder has
gone into thermal overload when the overload error indicator light is illuminated.
The welder will then cool itself down, and once the overload error indicator light is no longer
illuminated, welding can then re-commence.
Please note. Exceeding the machine’s duty cycle, cannot be considered grounds for warranty or return.
The term duty cycle indicates the percentage welding time available at the output current for each 10 min period
over 4 hours,
The specication plate on the machine list three given ratings at a given current and voltage.
NOTE: Amps refer to the Current setting - TIG DC setting duty cycle shown
60% 100%
320-Amps 250-Amps
22.8 Volts 20 Volts
For example this means when the machine is set at a current of 170 Amps in TIG-AC it can only weld for Two an
a half minutes in a Ten minute period. The power source is protected by a built in temperature protection device,
This will activate if the machine is operated in excess of its amperage and duty cycle rating.

MANUAL METAL ARC PROCESS (MMA WELDING)
When an arc is struck between the metal rod (electrode) and the workpiece, both the rod and workpiece
surface melt to form a weld pool. Simultaneous melting of the ux coating on the rod will form gas and slag
which protects the weld pool from the surrounding atmosphere. The slag will solidify and cool and must be
chipped off the weld bead once the weld run is complete (or before the next weld pass is deposited).
The process allows only short lengths of weld to be produced before a new electrode needs to be inserted in
the holder. Weld penetration is low and the quality of the weld deposit is highly dependent on the
skill of the welder.
TYPES OF ELECTRODES
Arc stability, depth of penetration, metal deposition rate and positional capability are greatly inuenced by the
chemical composition of the ux coating on the electrode. There are many types of Electrodes, and these
are generally matched to the base metal. For example if welding Mild Steel then select a Mild Steel (General
Purpose Electrode). Electrodes are identied by a universal numbering system (AWS Type code).
Base Metal Electrode Type Type
Mild Steel Mild Steel General Purpose 6013
Stainless Steel Stainless Steel 316L 316L
Dissimilar Metals Dissimilar 680 312
Cast Iron Nickel Arc 98 Ni99
High Strength Steel Low Hydrogen TC16
ELECTRODE SIZE SELECTION
Electrode size selection will be determined by the
thickness of the section being welded. A thicker
section will need a larger diameter electrode. The
table below shows the maximum size of electrodes
for average thicknesses of section (based on
General Purpose 6013 Electrode).
WELDING CURRENT
Welding current level is determined by the size
of electrode - the normal operating range and
current are recommended by manufacturers. Typical
operating ranges for a selection of electrode sizes
are illustrated in the table. As a rule of thumb when
selecting a suitable current level, an electrode will
require about 40 Amps per millimetre (diameter).
Therefore, the preferred current level for a 4mm
diameter electrode would be 160 Amps, but the
acceptable operating range is 140 to 180 Amps.
It is important to match the machine to the job

according to the manufacturer’s instructions.
ARC FORCE
Also called Dig and Arc Control. Gives a power source
variable additional amperage during low voltage
(short arc length) conditions while welding. Helps avoid

Direct current TIG (DC) welding is when the current
ows in one direction only. Compared with AC
(Alternating Current) TIG welding the current once
owing will not go to zero until welding has ended.
DC is used for TIG welding Mild Steel/Stainless
material and AC would be used for welding Aluminium.

12B For AC Welding
Select your requireed amperage by turning
the Multi-Function Control knob.
Press the knob to cycle the AC Balance;
this control allows the operator to adjust the
balance between the penetration (EN) and
cleaning action (EP) portions of the cycle.
It produces a greater cleaning action to
remove heavy oxidation and minimizes
penetration, which may help prevent burn-
through on thin materials. Reducing the
EN cycle, however, decreases tungsten
electrode life and increases balling action
because more heat is being directed into
the electrode. This creates a large ball at
the end of the tungsten and causes the arc
to lose stability, making it hard to direct the
arc weld puddle.
Press the knob to cycle the AC Frequency;
it controls the width of the arc cone. In-
creasing the AC frequency provides a more
focused arc with increased directional con-
trol. Decreasing the AC frequency softens
the arc and broadens the weld puddle for a
wider weld band.
