SAFETY
WARNING
ARC WELDING CAN BE HAZADOUS. PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP
CHILDREN AWAY. PACEMAKER WEARERS SHOULD CONSULT WITH THEIR DOCTOR BEFORE OPERATING. THIS PRODUCT IS
NOT INTENDED FOR USE BY PERSONS (INCLUDING CHILDREN) WITH REDUCED PHYSICAL, SENSORY OR MENTAL
DIFFERENT OR ARE REDUCED OR LACKING EXPERIENCE OR KNOWLEDGE, UNLESS SUCH PERSONS OR SUPERVISION
RECEIVED TRAINING FOR THE APPLIANCE BY A PERSON RESPONSIBLE FOR THEIR SAFETY. CHILDREN MUST
MONITORED TO ENSURE THAT THEY DO NOT LIKE TOY USED BY THE DEVICES. BE SURE THAT ALL INSTALLATION,
OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
1.a Electric current owing through any conductor causes
localized Electric and Magnetic Field (EMF). Welding current
creates EMF elds around welding cables and welding
machines.
1.b EMF elds may interfere with some pacemakers, and
welders having a pacemaker should consult their physican
before welding.
1.c All welders should use the following procedures in order to
minimize exposure to EMF elds from the welding circuit:
1.d.1 Route the electrode and work cables together – Secure
them with tape when possible.
1.d.2 Never coil the electrode lead around your body.
1.d.3 Do not place your body between the electrode and work
cables. If the electrode cable is on your right side, the work
cable should also be on your right side.
1.d.4 Connect the work cable to the workpiece as close as
possible to the area being welded.
2.a Use a shield with the proper lter and cover plates to protect
your eyes from sparks and the rays of the arc. Headshield and
lter lens should conform to ANSI Z87. I standards.
2.b Use suitable clothing made from durable ame-resistant
material to protect your skin and that of your helpers from the
arc rays.
2.c Protect other nearby personnel with suitable, non-ammable
screening and/or warn them not to watch the arc nor expose
themselves to the arc rays or to hot spatter or metal.
3.a The electrode and work (or ground) circuits are electrically
“hot” when the welder is on. Do not touch these “hot” parts with
your bare skin or wet clothing. Wear dry, hole-free gloves to
insulate hand.
3.b Insulate yourself from work and ground using dry insulation.
Make certain the insulation is large enough to cover your full
area of physical contact with work and ground.
In addition to the normal safety precautions, if welding
must be performed under electrically hazardous conditions
(in damp locations or while wearing wet clothing; on metal
structures such as oors, grating or scaffolds; when in
cramped positions such as sitting, kneeling or lying, if there
is a high risk of unavoidable or accidental contact with the
workpiece or ground) use the following equipment:
• Semiautomatic DC Constant Voltage (Wire) Welder.
• DC Manual (Stick) Welder.
• AC Welder with Reduced Voltage Control.
3.c In semiautomatic or automatic wire welding, the electrode,
electrode reel, welding head, nozzle or semiautomatic welding
gun are also electrically “hot”.
3.d Always be sure the work cable makes a good electrical
connection with the metal being welded. The connection should
be as close as possible to the area being welded.
3.e Ground the work or metal to be welded to a good electrical
(earth) ground.
3.f Maintain the electrode holder, work clamp, welding cable
and welding machine in good, safe operating condition. Replace
damaged insulation.
3.g Never dip the electrode in water for cooling.
3.h Never simultaneously touch electrically “hot” parts of
electrode holder to two welders because voltage between the
two can be total of the open circuit voltage of both welders.

SAFETY
4.a Welding may produce fumes and gases hazardous to
health. Avoid breathing these fumes and gases. When welding,
keep your head out of fume. Use enough ventillation and/or
exhaust at the arc to keep fumes and gases away from the
breathing zone. When welding with electrodes which require
special ventilation such as stainless or hard facing (see
instructions on container or MSDS) or on lead or cadmium
plated steel and other metals or coatings which produce
highly toxic fumes, keep exposure as low as possible and
below Threshold Limit Values (TLV) using local exhaust
or mechanical ventilation. In conned spaces or in some
circumstances, outdoors, a respirator may be required.
Additional precautions are also required when welding on
galvanized steel.
4.b Do not weld in locations near chlorinated hydrocarbon vapors
coming from degreasing, cleaning or spraying operations. The
heat and rays or the arc can react with solvent vapors to form
phosgene, a highly toxic gas, and other irritating products.
4.c Shielding gases used for arc welding can displace air and
cause injury or death. Always use enough ventilation, especially
in conned areas, to insure breathing air is safe.
4.d Read and understand the manufacturer’s instructions for
this equipment and the consumables to be used, including the
material safety data sheet (MSDS) and follow your employer’s
safety practices. MSDS forms are available from your welding
distributor or from the manufacturer.
5.a Turn off input power using the disconnect switch at the fuse
box before working on the equipment.
5.b Install equipment in accordance with the national standard,
all local standards and the manufacturer’s recommendations.
5.c Ground the equipment in accordance with the national
standards and the manufacturer’s recommendations.
6.a Remove re hazards from the welding area. If this is not
possible, cover them to prevent the welding sparks from starting
a re. Remember that welding sparks and hot materials from
welding can easily go through small cracks and openings to
adjacent areas. Avoid welding near hydraulic lines. Have a re
extinguisher readily available.
6.b When not welding, make certain no part of the electrode
circuit is touching the work or ground. Accidental contact can
cause overheating and create a re hazard.
6.c Do not heat, cut or weld tanks, drums or containers until the
proper steps have been taken to insure that such procedures
will not cause ammable or toxic vapors from subtances inside.
They can cause an explosion even though they have been
“cleaned”.
6.d Sparks and spatter are thrown from the welding arc. Wear
oil free protective garments such as leather gloves, heavy shirt,
cufess trouses, high shoes and a cap over your hair.
7.a Use only compressed gas cylinders containing the correct
shielding gas for the process used and properly operating
regulators designed for the gas and pressure used. All hoses,
ttings, etc. should be suitable for the application and maintained
in good condition.
7.b Always keep cylinders in an upright position securely
chained to an undercarriage or xed support.
7.c Cylinder should be located:
• Away from areas where they may be struck or subjected to
physical damage.
• A safe distance from arc welding or cutting operations and any
other source of heat, sparks, or ame.
7.d Never allow the electrode, electrode holder or any other
electrically “hot” parts to touch a cylinder.
7.e Keep your head and face away from the cylinder valve
outlet when opening the cylinder valve.

SELECT SUITABLE LOCATION
This power source should not be subjected to rain, nor should
any parts of it be submerged in water. Doing so may cause
improper operation as well as pose a safety hazard. The best
practice is to keep the machine in a dry, sheltered area.
The bottom of machine must always be placed on a rm,
secure, level surface. There is a danger of the machine
toppling over if this precaution is not taken.
Place the welder where clean cooling air can freely circulate in
through the front louvers and out through the rear side. Water,dirt,
dust or any foreign material that can be drawn into the welder
should be kept to a minimum. Failure to observe these precautions
can result in excessive operating temperatures and nuisance
shutdowns. Locate the machine away from radio controlled
machinery. Normal operation of the welder may adversely affect
the operation of RF controlled equipment, which may result in
bodily injury or damage to the equipment.

CAUTION

SECURITY CAUTIONS
ELECTRIC SHOCK can kill.
• Keep the electrode holder and cable
insulation in good condition.
• Do not touch electrically live parts or
electrode with skin or wet clothing.
• Insulate yourseld from work and ground.
• Turn the input line Switch on the arcweld machines “Off”
bedore connecting or disconnecting output cables or other
euipment.
For secure electrical connection, the power source sockets
connecting cable plugs must be tightened. Damage may
occur to the output socket or welding performance maybe
compromised.
To avoid interference problems with other equipment
and to achieve the best possible operation, route all cables directly
to the work. Avoid excessive lengths and do not coil excess cable.
OUTPUT CONNECTIONS
A quick disconnect system using Europe quick cable plugs is used
for the welding cable connections. Refer to the following sections
for more information on connecting the machine for operation of
stick welding(SMAW) or TIG welding.
STICK WELDING (SMAW)
First determine the proper electrode polarity for the electrode to be
used. Consult the electrode data for this information. Then connect
the output cables to the output terminals of the machine for the
selected polarity. Shown here is the connection method for DC(+)
welding. (See Figure B.1)
Connect the welding cable to the (+) terminal and the work clamp
to the (-) terminal. Insert the connector with the key lining up with
the keyway and rotate approximately 1/4 turn clockwise. Do not
over tighten.
For DC(-) welding, switch the cable connections at the machine
so that the welding cable is connected to (-) and the work clamp is
connected to (+). (See Figure B.2)
TIG WELDING (GTAW)
The Arcweld®machine does not have a built in Gas Solenoid so a
piece gas valve TIG Torch with gas valve is required. A TIG Torch
adapter is also required. Refer to the accessories section for more
informatin about TIG Torches and required adapter. Most TIG
welding is done with DC(-) polarity shown here.(See Figure B.3)
If DC(+) polarity is necessary switch the cable connections at the
machine.
Connect the torch cable to the (-) terninal of the machine and the
work clamp to (+) terminal. Insert the connector with key lining up
with the key way and rotate approximately 1/4 turn clockwise. Do
not over tighten. Finally, connect the adapter gas hose to the gas
regulator of the cylinder gas.
Stricking arc of TIG operation
When the tungsten electrode touches the workpiece, the short-
circuit current is only 10A. After generating arc, current can rise
to the preset welding current. If the tungsten electrode touches
the workpiece during welding, the current will drop to 10A within
2s, which can reduce tungsten damage and prolong the tungsten
electrode life.

Auto Adaptive Arc Force (with stick welding)
The arc force function is activated during stick welding. This
function increases temporary the output current, used to clear
intermittent connections between the electrode and the weld
puddle that occur during stick welding.
This is an active control feature that guarantees the best
arrangement between the arc stability and spatter presence. The
control determines the amount of current to apply to break the
metal drop that is being transferred from the electrode to the work
piece to guarantee the arc stability, but not too high to minimize
spatter around the welding puddle. That means:
• Electrode/work piece sticking prevention, also with low current
values
• Spatters reduction
The welding operations are simplied and the welded joints looks
better, also brush before welding for better results.
With the Stick welding are also enabled the following features:
• Hot Start: This is a temporary increase in the initial welding
current. This helps ignite the arc quickly and reliably.
• Anti-Sticking: This is a function that decreases the output
current of the machine to a low level when the operator makes
an error and sticks the electrode to the work piece. This decrease
the current allows the operator to remove the electrode from the
electrode holder without creating large sparks that can damage
the electrode holder.

ELECTRODE SELECTION
The electrode diameter selection is based on the workpiece
thickness, welding position, joint form, welding layer, etc. Please
refer to the following table.
The relationship between workpiece thickness and electrode
diameter:
The welding current reference for different electrode diameter:
1.Electrode should be drying according to user manual before
using. For reducing the hydrogen of the molten pool and welding
seam, and avoiding the blowhole and cold crack.
2.In the welding process, the arc must not be too long; otherwise,
it will cause unstable arc burning, large spatter, light penetration,
undercut, blowhole, etc. If the arc is too short, it will cause electrode
stick.
3.In MMA welding the arc length is usually equal to 0,5~1,0 time
of the electrode diameter. The basic electrode’s arc length is not
beyond the electrode diameter, it’s better to choose the short arc
welding; the acid electrode’s arc length is equal to the electrode
diameter.
