2.8.1. Installing gas bottle

Always fasten gas bottle properly in vertical position in a special holder on the wall or
on a carriage. Remember to close gas bottle valve after having finished welding.
The following installing instructions are valid for most gas flow regulator types:
1. Step aside and open the bottle valve (A) for a while to blow out possible impurities from
the bottle valve.
2. Turn the press regulation screw (B) of the regulator until no spring pressure can be felt.
3. Close needle valve, if there is one in the regulator.
4. Install the regulator on bottle valve and tighten connecting nut (C) with a wrench.
5. Install hose spindle (D) and jacket nut (E) into gas hose and tighten with hose clamp.
6. Connect the hose with the regulator and the other end with the power source. Tighten the
jacket nut.
7. Open bottle valve slowly. Gas bottle pressure meter (F) shows the bottle pressure. Note! Do
not use the whole contents of the bottle. The bottle should be filled when the bottle pressure
is 2 bar.
8. Open needle valve if there is one in the regulator.
9. Turn regulation screw (B) until hose pressure meter (G) shows the required flow (or pressure).
When regulating flow amount, the power source should be switched on and gas test button
on the panel pressed simultaniously.
Always close bottle valve after having finished welding. If the machine will be out of use for a
long time, unscrew the pressure regulation screw.

3. OPERATION

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 intended to specialized TIG welding machines with HF
arc ignition and versatile panel functions depending on the panel in use. The panels predominatley
for TIG welding are MTL, MTX 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

MTX and MTM panels include the synergic pulsed TIG process in which you only need to adjust
the welding current while other pulse parameters are pre-programmed. Pulsing frequency is high
causing concentrated arc and increased welding speed.

3.1.4. Long Pulsed TIG

This method gives you the possibility to adjust all the pulse parameters. It can be used for easier
weld pool control. It is included in MTX and MTM panels.
