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
recycling facility.

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
