1. GENERAL

These instructions describe the use of Kemppi's Master M welding equipment designed for light- to medium-duty pro-

fessional use in MIG/MAG welding.

Master M welding machines include both manual and automatic welding processes. Pulse welding is possible with the

Master M 355 series machines.

Master M product series Master M device model

Master M 353 Master M 353 G

Master M 353 GM

Master M 355 Master M 355 G

Master M 355 GM

Master M is designed to be used together with Kemppi's Flexlite GX MIG welding guns with euro connector.

Master M can be used also for TIG * and MMA ** welding.

* TIG welding requires the use of a dedicated Flexlite TX TIG torch with euro connector.

** MMAwelding requires a dedicated DIX-euro adapter.
