equipment. 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 equipment must be familiar with:

○ its operation

○ location of emergency stops

○ its function

○ relevant safety precautions

○ welding and cutting or other applicable operation of the equipment

2. The operator must ensure that:

○ no unauthorised person is stationed within the working area of the equipment

when it is started up

○ no-one is unprotected when the arc is struck or work is started with the

equipment

3. The workplace must:

○ be suitable for the purpose

○ be free from drafts

1 SAFETY

0463 344 101 -5- © ESAB AB 2022

4. Personal safety equipment:

○ Always wear recommended personal safety equipment, such as safety glasses,

flame-proof clothing, 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

○ Work on high voltage equipment may only be carried out by a qualified

electrician

○ 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

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 344 101 -6- © ESAB AB 2022

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 use on closed containers.

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

PROTECT YOURSELF AND OTHERS!

CAUTION!

This product is solely intended for arc welding.

WARNING!

Do not use the power source for thawing frozen pipes.

CAUTION!

Class A equipment is not intended for use in residential

locations where the electrical power is provided by the

public low-voltage supply system. There may be

potential difficulties in ensuring electromagnetic

compatibility of class A equipment in those locations,

due to conducted as well as radiated disturbances.

NOTE!

Dispose of electronic equipment at the recycling

facility!

In observance of European Directive 2012/19/EC on

Waste Electrical and Electronic Equipment and its

implementation in accordance with national law,

electrical and/or electronic equipment that has reached

the end of its life must be disposed of at a recycling

facility.

As the person responsible for the equipment, it is your

responsibility to obtain information on approved

collection stations.

For further information contact the nearest ESAB dealer.

ESAB has an assortment of welding accessories and personal protection equipment

for purchase. For ordering information contact your local ESAB dealer or visit us on

our website.

2 INTRODUCTION

Mig C170 3ph, Mig C200 3ph and Mig C250 3ph are step controlled power sources of a

compact design, intended for welding with solid steel, stainless steel or aluminium wire as

well as tubular wire with or without shielding gas. It is possible to weld with homogeneous

wire/shielding gas and weld with gasless tubular wire by switching the + and - connections on

the switching terminal by the wire feed unit.

ESAB accessories for the product can be found in the "ACCESSORIES" chapter of

this manual.

2.1 Equipment

The power source is supplied with:

• Welding torch

• Return cable with return clamp

• Shelf for gas cylinder

• Instruction manual
