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 o 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 dierent 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.
