OperatiOn

NOTE!

Welding in places presenting an immediate fire or explosion hazard is forbidden!

Welding fumes may cause injury, take care of sufficient ventilation during welding!

3.1 Welding processes

3.1.1 mma welding

MMA welding, as well as carbon arc gouging, is possible with all Master MLS and Mastertig

MLS power sources with all MLS panel versions when switched to MMA process.

3.1.2 tig welding

Mastertig MLS power sources are designed especially for TIG welding. They are equipped

with HF spark ignition and versatile panel functions depending on the panel used. The panels

predominantly for TIG welding are MTL, MTX, MTZ and MTM. Also the MEL and MEX panel on

Master MLS power source can be used for TIG welding with contact ignition.

3.1.3 synergic pulsed tig welding (a)

(a)

(b)

MTX, MTZ and MTM panels include the synergic pulsed TIG process, in which you only need to

adjust the welding current while other pulse parameters are programmed. Pulsing frequency

is high, which guarantees concentrated arc and increased welding speed.

3.1.4 long pulsed tig welding (b)

This method gives you the possibility to adjust all pulse parameters. Weld pool control is also

easier. Long pulsed TIG welding is included in MTX, MTZ and MTM panels.

3.2 Operation functions

3.2.1 power source

NOTE!

Always switch the machine on and off from main switch. Do not use the mains plug for

switching!

Never watch the arc without a proper face shield designed for arc welding! Protect yourself and the

surroundings against welding arc and hot spatters!

3.2.2 function panels

Before welding starts, welding settings suitable for the work piece are chosen with the

function panel. See 3.1. Welding processes.
The Kemppi Multi Logic System, MLS™, allows you to select from different function panels

according to your welding application. MEL and MEX panels are designed for MMA welding.

MTL, MTX, MTZ and MTM panels are for TIG welding with basic functions, or with pulsed

TIG, 4T-LOG, or MINILOG control of welding current, or with memory channels. See also 3.1.
