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!
Read and understand the instruction manual
before installing or operating.
Do not use the power source for thawing frozen pipes.
WARNING!
This product is solely intended for arc welding.

3 INTRODUCTION
ESABMig C280 & ESABMig C340 are step controlled power sources in a compact
design, intended for welding with solid steel, stainless steel or aluminium wire as well
as tubular wire with or without shielding gas.
The possibility of welding with homogeneous wire/shielding gas and welding with
gasless tubular wire is obtained by switching the + and −connections on the
switching terminal above the wire feed unit.
ESAB’s accessories for the product can be found on page 176.
