3 INTRODUCTION
The ESABMig 405 and ESABMig 505 are step switched power sources designed for
MIG/MAG–welding together with wire feed units ESABFeed 30, ESABFeed 48
and the most of ESAB wire feeders.
The power units are fan–cooled and equipped with thermal overload protection.
The machines can be fitted with an instrument for display of current and voltage. It
incorporates a hold function and can be calibrated.
The machines can be fitted with a flow guard.
ESAB’s accessories for the product can be found on page 203.
