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.
