Electrode Welding Process; Generator Operation - LORCH MicorStick Operation Manual

 Connect the mains cable.
9 The device is in standby mode.
Battery operation (optional)
For mobile use, the machine can be used in battery opera-
tion with a Lorch MobilePower battery pack.
 Connect the battery cable.
9 The device is switched on.
When working with battery operation, ob-
i
serve the following:
First, connect the battery cable to the ma-
chine coupling on the welding machine and
then switch the MobilePower battery pack on.
Always switch the MobilePower battery pack
off before disconnecting the device coupling of
the battery cable.
Never disconnect the battery cable when op-
erating the welding machine.

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 weld-
ing equipment, the output power of the generator
must at least match the input power of the welding
equipment (see Technical Data).
– If the generator is overloaded, then arc pulsing or
an arc breakaway is possible.
Mains extension cables
‰ Only use intact mains extension cables which offer the
specified protection.
‰ Coiled cables may heat up considerably. Always un-
wind extension cables fully.
When particularly long mains extension cables are used,
the mains voltage on the machine may fall to such an ex-
tent that the welding power falls. Shorten the extensions
and/or use extensions with a larger cable cross-section.

12.4 Electrode welding process

Connecting the electrode cable
Connect the electrode welding cable to the negative 3
or positive 4 socket and secure the cable by rotating it
clockwise.
Note the manufacturer's information when
i
selecting a suitable stick electrode. The
- 22 -
Electrode welding with positive (+) electrode:
 Connect the electrode holder to the positive terminal
4 of the machine and secure it by turning the plug to
the right.
Electrode welding with negative (-) electrode:
 Connect the electrode holder to the negative terminal
3 of the machine and secure it by turning the plug to
the right.
 Push the lever on the handle of the electrode holder.
Clamp an electrode with the exposed end in the hold-
er. Note the notches on the inner side of the two jaws.
12.5 TIG welding process
i
Installing electrodes
 Unscrew the clamping cap 55.
 Remove the electrode 54 from the collet 53.
 Grind the end of the electrode 54.
 Slide the electrode 54 into the collet 53.
 Insert the electrode 54 into the torch and firmly tighten
the clamping cap 55.
i
‰ The collet 53, collet body 51 and electrode 54 must
have the same diameter.
‰ The gas nozzle 50 must be matched to the electrode
diameter.
Connecting the TIG torch
 Connect the TIG torch 58 to the negative terminal 3
and secure it by turning it to the right.
Connecting the inert gas cylinder
 Secure the inert gas cylinder 60, e.g. by using a secur-
ing chain.
909.2049.9-00
Before start-up
electrode diameter is dependent upon the
thickness of the material to be welded.
For TIG welding you require a TIG valve
torch (Type LTV 1700) for this machine.
IV
Do not dismantle the collet body 51 and the
gas nozzle 50.
When converting the torch to a different elec-
trode diameter, please pay attention to the
following.
