3 INTRODUCTION
The ESABMig C420w/C420sw are step–controlled compact welding power units incorporating wire
feed mechanism intended for MIG/MAG welding with solid wires of steel, stainless steel or aluminium,
and cored wires with or without shielding gas. The ESABMig C420w/420sw are equipped with cooling
liquid system for welding torch. The ESABMig C420/420s are not equipped with cooling system and
can operate only with appropriate gas cooled torches.
The ESABMig C420w/420 is equipped with standard control unit (manual setting of all welding
parameters) and ESABMig C420sw/420s contains additional synergy control facility (preprogrammed
welding parameters; see also chapter 6.4).
The power units are fan–cooled and equipped with thermal overload protection.
The machines can be fitted with a flow guard (C420sw/C420w).
ESAB’s accessories for the product can be found on page 238.
