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
 If necessary, switch the system on by pressing button
17 for 2 sec.
 Keep pressing button 16 until the electrode operating
function is selected.
9 The electrode icon MMA or CEL (LED 13 or 14) lights
up.
 Use control knob 12 to set the desired welding current.
Arc ignition
 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
 If necessary, switch the system on by pressing button
17 for 2 sec.
 Keep pressing button 16 until the TIG operating func-
tion is selected.
9 The TIG icon (LED 15) lights up.
 Use control knob 12 to set the desired welding current.
Arc ignition
 Open the valve 56 on the TIG welding torch.
 Briefly touch the workpiece with the tip of the elec-
Â
trode at the point to be welded.
 Lift the electrode a little.

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.
