Before start-up
 Insert the control plug of the TIG torch into
Socket 4.
 Connect the gas pipe of the TIG torch to Gas
connection 5.
 Connect the mains or battery cable.
 Switch the machine on by pressing the On/Off
button 28 for 2 sec.
 Set the desired welding current using rotary
knob 19.
9 The machine is now ready for welding.

13.1 Fastening the transportation belt
II
 Thread the transportation belt into the welding
machine and plastic slides. See sequence of the
numbering in the picture.
13.2 Connecting the ground cable III
When selecting the working space, ensure that
the ground cable and the ground clamp can be
fastened properly.
The ground clip must be fastened to an ex-
posed location of the welding table or compo-
nent, so that it is highly conductive. It must be
located in the immediate vicinity of the welding
area, so that the welding current cannot seek its
own return path across machine parts, ball bear-
ings or electric circuitry.
Do not place the ground clamp on the welding
machine, as otherwise the welding current will
be carried via the protective conductors and it
will destroy these.
Never attach the workpiece connection loosely.
Connect the ground clamp firmly to the welding
bench or the workpiece.
13.3 Connecting the power supply
Mains cable with device coupling
Danger of death through electrocu-
tion!
If the plug-in mains cable is used in-
correctly when humidity or moisture
is present, particularly outdoors,
then electrocution is possible.

Mains operation
Before commissioning the machine, ensure that
a suitable mains connection is available. The fuse
must meet the requirements stated in the techni-
cal data.
 Connect the mains cable.
9 The device is in standby mode.
Battery operation (optional)
For mobile use, the machine can be used in
battery operation with a Lorch MobilePower 1
battery pack.
The welding device may only be op-
 Connect the battery cable.
9 The device is switched on.
When working with battery operation,
i
Generator operation
Alternatively, the machine can be connected to a
power generator. Please note:
– If you want to use the full power range of
the welding equipment, the output power of
the generator must at least match the input

When working in mains operation,
observe the following:
First, connect the mains cable to the
machine coupling on the welding
machine and then connect the mains
cable to the mains plug in the mains
socket.
Always disconnect the mains plug
from the mains socket before dis-
connecting the machine coupling.
erated with the appropriate Mobile-
Power 1 battery!
observe the following:
First, connect the battery cable to the
machine coupling on the welding ma-
chine and then switch the MobilePow-
er 1 battery pack on.
Always switch the MobilePower 1 bat-
tery pack off before disconnecting the
device coupling of the battery cable.
Never disconnect the battery cable
when operating the welding machine.
