WARNING

Read and understand the instruction manual before installing or operating.

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

cutting. Ask for your employer's safety practices which should be based on manufacturers' hazard

data.

ELECTRIC SHOCK - Can kill

SInstall and earth the unit in accordance with applicable standards.

SDo not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing.

SInsulate yourself from earth and the workpiece.

SEnsure your working stance is safe.

FUMES AND GASES - Can be dangerous to health

SKeep your head out of the fumes.

SUse 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.

SProtect your eyes and body. Use the correct welding screen and filter lens and wear protective

clothing.

SProtect bystanders with suitable screens or curtains.

FIRE HAZARD

SSparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.

NOISE - Excessive noise can damage hearing

SProtect your ears. Use earmuffs or other hearing protection.

SWarn bystanders of the risk.

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

PROTECT YOURSELF AND OTHERS!

WARNING

Do not use the power source for thawing frozen pipes.

CAUTION

This product is solely intended for arc welding.

Dispose of electronic equipment at the recycling facility!

In observance of European Directive 2002/96/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

2 INTRODUCTION

Mig C141, Mig C151, Mag C171, Mag C201 and Mag C251 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's accessories for the product can be found on page 26.

2.1 Equipment

The power source is supplied with:

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.

Enclosure class

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

objects or water. Equipment marked IP23 is designed for indoor and outdoor use.

Application class

The symbol indicates that the power source is designed for use in areas with increased

electrical hazard.

4 INSTALLATION

The installation must be carried out by a professional.

Note!

Connect the power source to the electricity mains with a network impedance of (C141 - 0.41; C151 -

N/A; C171 - N/A; C201 - 0.32; C251 - 0.212) ohm or lower. If the network impedance is higher, there

is a risk of flicker in the illuminators.

CAUTION

This product is intended for industrial use. In a domestic environment this product may

cause radio interference. It is the user's responsibility to take adequate precautions.

4.1 Location

Position the welding power source in such a way that its cooling air inlets and outlets

are not obstructed.

4.2 Assembly of components

For packing and shipment of the machine the wheels are detached from the unit.

Before use attach the wheels according to instruction.
