SAFETY
Users of ESAB welding equipment have the ultimate responsibility for ensuring that
anyone who works on or near the equipment observes all the relevant safety
precautions. Safety precautions must meet the requirements that apply to this type of
welding equipment. The following recommendations should be observed in addition to
the standard regulations that apply to the workplace.
Trained personnel well acquainted with the operation of the welding equipment must
carry out all the work. Incorrect operation of the equipment may lead to hazardous
situations, which can result in injury to the operator and damage to the equipment.
1. Anyone who uses the welding equipment must be familiar with:
• its operation
• location of emergency stops
• its function
• relevant safety precautions
• welding
2. The operator must ensure that:
• no unauthorized person is stationed within the working area of the equipment
when it is started up.
• no one is unprotected when the arc is struck
3. The workplace must:
• be suitable for the purpose
• be free from drafts
4. Personal safety equipment
• Always wear recommended personal safety equipment, such as safety glasses,
flameproof clothing, and safety gloves.
• Do not wear loose—fitting items, such as scarves, bracelets, rings, etc., which
could become trapped or cause burns.
5. General precautions
• Make sure the return cable is connected securely.
• Only a qualified electrician may carry out work on high voltage equipment.
• Appropriate fire extinguishing equipment must be clearly marked and close at
hand.
• Lubrication and maintenance must not be carried out on the equipment during
operation.
Read and understand the instruction manual before installing or operating.
ESAB can provide you with all necessary welding protection and accessories.

WARNING
Arc welding and cutting can be injurious to yourself and others. Take
precautions when welding.
Ask for your employer’s safety practices which should be based on manufacturers’
hazard data.
ELECTRIC SHOCK –Can kill
• Install and earth the welding unit in accordance with applicable
standards.
• Do not touch live electrical parts or electrodes with bare skin, wet
gloves or wet clothing.
• Insulate yourself from earth and the workpiece.
• Ensure your working stance is safe.
FUMES AND GASES –Can be dangerous to health
• Keep your head out of the fumes.
• Use ventilation, extraction at the arc, or both, to take fumes and gases
away from your breathing zone and the general area.
ARC RAYS –Can injure eyes and burn skin.
• Protect your eyes and body. Use the correct welding screen and filter
lens and wear protective clothing.
• Protect bystanders with suitable screens or curtains.
FIRE HAZARD
• Sparks (spatter) can cause fire. Make sure therefore that there are no
inflammable materials nearby.
NOISE –Excessive noise can damage hearing
• Protect your ears. Use earmuffs or other hearing protection.
• Warn bystanders of the risk.
MALFUNCTION –Call for expert assistance in the event of malfunction.
PROTECT YOURSELF AND OTHERS!
CAUTION!
This product is solely intended for arc welding
Do not dispose of electrical equipment together with normal waste!
In accordance with national law, electrical equipment that has
reached the end of its life must be collected separately and returned
to an environmentally compatible recycling facility. As the owner of
the equipment, you should get information on approved collection
systems from the local representative. By applying this Directive you
will improve the environment and human health

CAUTIONS FOR INSTALLATION
Provide a Switch Box for every Welding Power Source, and use designated
fuse
Tolerance of Power Voltage Variation is 10% of rated input voltage.
a) Installation place
Install in the place where less moisture and dust exist. Avoid direct sunlight and
rain, and maintain ambient temperature within –10o to +45o C as much as
possible.
Keep the welding power source at least 20 cm. away from the wall (if any).
In case of installation of more two units side by side, a distance of more than 20
cm is recommended between the two power sources.
Use a shield to protect the welding arc in case of excessive air draft.
b) Ventilation
Adequate ventilation is recommended at the place of installation. For
example the following guideline should be followed:
a) In case of the area being more than 300 square meters (per unit), no
ventilation is required, provided the room is not completely airtight.
b) In case of the area being less than 300 square meters and the welding
is continuously performed, adequate ventilation is recommended with
the help of vent fan or exhaust duct.
c) While performing the grounding work, it is recommended that a skilled
electrician does the work.

Indicating light
Only Green light on: The power is on.
Green light on, Red light on: The machine is overheated. The machine will go back to
working condition, if the inner temperature of machine returns to the allowed level.

8
MIG MODE
Put MMA/ MIG switch on power source in MIG mode.
Crater Control (2T/4T)
Usually there is a crater at the end of welding. Adjust Crater Voltage and Current to fill
up the crater by arc ending current (less than 40%-70% of welding current) and
improve the welding quality. It also selects 2T/4T operation of the machine.
Soft wire feeding
In order to get the satisfying welding quality, the machine feed the wire at preset low
speed before wire touch the work piece. The speed will reach the normal level after
striking arc. It means striking arc fail if the current is not detected during this stage.
This kind of striking arc mode can improve the success of striking arc and ensure the
reliable and stable arc.
Burn back time
When the trigger of torch is switched off, the wire feeding will continue because of
inertia. So the wire will go out to the top end of torch after the welding. It will cause the
stick of wire to the work piece, thus bring the difficulty to the next welding. The burn
back is set in the machine to solve this problem. The machine will keep output voltage
during certain time to keep wire burning.
Current Inductance control
It means electronic reactor. It can adjust wire burning power by changing the current
changing speed, and reduce the spatter.
Ball cutting
Usually there is a big droplet at the end of wire after welding. And slag will stick on the
low surface of the droplet. It will cause difficulty of striking arc. The ball cutting circuit is
designed to cut the droplet automatically after welding.
Post-gas
3 seconds post-gas time is set to protect the welding area after welding.

2. Wire Inch Push Button.
3. Welding Voltage Setting.
MMA MODE
Put MMA/MIG switch on power source in MMA mode.
Welding current can be set by MMA current setting knob on the power source.
