Energy-saving function using battery
pack
If the welding machine is connected to a MobilePower
battery pack, then the energy-saving function of the bat-
tery pack is active and the energy-saving function of the
welding machine is deactivated.
‰
When the welding machine is connected to the bat-
tery pack and the battery pack is switched on, then the
welding machine is always switched on.
‰
If the welding device is not used for some time, then
the battery pack will switch to Standby mode automati-
cally and switch the welding machine off.
‰
Refer to the MobilePower 1 operating manual.
Before switch-on, ensure that neither the
electrode holder nor the electrode is touching
the welding table, the workpiece or another
electrically-conductive object, to ensure that
you do not unintentionally ignite arcing on
switch-on. An unintentionally ignited arc can
damage the electrode holder, the welding ta-
ble, the workpiece and the machine.
14.2 Electrode welding process
Switch on the system
Â
If necessary, switch the system on by pressing button
17 for 2 sec.
Â
Keep pressing button 16 until the electrode operating
function is selected.
9
The electrode icon MMA or CEL (LED 13 or 14) lights
up.
Â
Use control knob 12 to set the desired welding current.
Arc ignition
Â
Briefly touch the workpiece at the point to be welded
using the electrode and lift the electrode a little.
9
The arc burns between the workpiece and the elec-
trode.
Hotstart
‰
In the electrode welding method, a hotstart of 125 %
of the set welding current is used for 1 second for igni-
tion. Like the welding current, the hotstart is limited to
a maximum of 150 A.

14.3 TIG welding process
Switch on the system
Â
If necessary, switch the system on by pressing button
17 for 2 sec.
Â
Keep pressing button 16 until the TIG operating func-
tion is selected.
9
The TIG icon (LED 15) lights up.
Â
Use control knob 12 to set the desired welding current.
Arc ignition
VIII
Â
Open the valve 56 on the TIG welding torch.
  
Briefly touch the workpiece with the tip of the elec -
trode at the point to be welded.
  
Lift the electrode a little.
9
The arc burns between the workpiece and the elec-
trode.
Upslope
‰
A short-circuit current of 60 A is used for igniting during
the TIG welding process. The upslope takes place with
115 A/s until the set welding current is reached.
