WARNING!

Arc welding and cutting can be injurious to yourself and others. Take precautions

when welding and cutting.

ELECTRIC SHOCK - Can kill

• Install and ground the unit in accordance with instruction manual.

• Do not touch live electrical parts or electrodes with bare skin, wet gloves or

wet clothing.

• Insulate yourself from work and ground.

• Ensure your working position is safe

ELECTRIC AND MAGNETIC FIELDS - Can be dangerous to health

• Welders having pacemakers should consult their physician before welding.

EMF may interfere with some pacemakers.

• Exposure to EMF may have other health effects which are unknown.

• Welders should use the following procedures to minimize exposure to

EMF:

○ Route the electrode and work cables together on the same side of

your body. Secure them with tape when possible. Do not place your

body between the torch and work cables. Never coil the torch or work

cable around your body. Keep welding power source and cables as

far away from your body as possible.

○ Connect the work cable to the workpiece as close as possible to the

area being welded.

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.

NOISE - Excessive noise can damage hearing

Protect your ears. Use earmuffs or other hearing protection.

1 SAFETY

0463 697 001 -6- © ESAB AB 2021

MOVING PARTS - Can cause injuries

• Keep all doors, panels and covers closed and securely in place. Have only

qualified people remove covers for maintenance and troubleshooting as

necessary. Reinstall panels or covers and close doors when service is

finished and before starting engine.

• Stop engine before installing or connecting unit.

• Keep hands, hair, loose clothing and tools away from moving parts.

FIRE HAZARD

• Sparks (spatter) can cause fire. Make sure that there are no inflammable

materials nearby.

• Do not touch parts bare handed.

• Allow cooling period before working on equipment.

• To handle hot parts, use proper tools and/or insulated welding gloves to

prevent burns.

MALFUNCTION - Call for expert assistance in the event of malfunction.

PROTECT YOURSELF AND OTHERS!

CAUTION!

This product is solely intended for arc welding.

WARNING!

Specification of the torch cooling circuit

(for water cooled torches only)

• min. water pressure: 2.5bar

• max. water pressure: 4.0bar

The necessary cooling power is dependent of the application, the welding parameters and

the length of the torch. Sufficiency of available cooling power can be verified by measuring

the return temperature of the cooling fluid. If the return temperature is above 60°C (140°F),

the cooling power should be increased or the welding current should be reduced.

For other application parameters or longer cables, refer to additional documents that may

have been included with your torch.

CAUTION!

Return temperatures of more than 60°C can cause damage or destruction of the

torch. The cooler must always be filled with sufficient cooling liquid, refer the user

manual of the cooling unit. In case of a high thermal load on the torch, use a cooler

with sufficient capacity. Use only special cooling fluid containing corrosion inhibitors

for welding torches. We recommend using ESAB CoolingFluid.

Duty cycle

The duty cycle refers to the time as a percentage of a ten-minute period that you can weld or

cut at a certain load without overloading. The duty cycle is valid for 40°C (104°F), or below.

Protection class

The torches protection class machine side (EN 60 529) IP3X

Enclosure class

The IP code indicates the enclosure class, i.e. the degree of protection against penetration

by solid objects of 2.5 mm Ø and greater. Omitting second characteristic numeral.
