WARNING!

result in personal injury.
NOTE.
Remember to use the correct contact tip in the torch for the wire diameter used. The
torch is fitted with a contact tip for
must change the contact tip. The wire liner fitted in the torch is recommended for
welding with Fe and Ss wires. Change the liner to the PTFE type for welding Al or
Brazing (CuSi). See 7.2 regarding how to change the wire liner.

Changing the feed roller groove
The machine is delivered with the feed roller set for
want to use it for
0.6mm wire you must change the groove in the feed roller.

3. Switch off the machine.
4. Use a 2mm Allen key to open the locking screw about half a turn.
5. Pull the feed roller off the shaft and turn it around. See marking on the side of the
feed roller for suitable wire diameters.
6. Put the roller back on the shaft and make sure it goes all the way in. You may

Shielding gas
The choice of suitable shielding gas depends on the material. Typically mild steel is
welded with mixed gas (Ar + CO2) or carbon dioxide. Stainless steel can be welded
with mixed gas (Ar + CO2 or O2) and Aluminium with pure argon. MIG/MAG brazing
(CuSi) uses pure argon or mixed gas (Ar + O2). Check the recommended gas for the
welding wire you want to use. QSett mode (see 6.2.2) will automatically set the
optimal welding arc with the gas you use.
6.9
Overheating protection
Overheating is indicated on the LCD with error code E4. A thermal overload cutout pro-
tects the unit against overheating by disabling the welding if overheating occurs. The
cutout resets automatically when the unit has cooled down.
