Connection of welding cables
Connect the welding cables and the return
current cable to the front of the machine.
Please note that the plug must be turned 45
degrees after insertion into the socket -
otherwise the plug can be damaged due to ex-
cessive contact resistance.
Always connect the TIG connection in the
minus (-) socket (3) and the return current
cable in the plus (+) socket (4).
The control signals from the TIG torch are
transformed to the machine through the
circular 7-pin plug (5). When the plug has
been assembled please secure it by turning
the "circulator" clockwise.
COATED
ELECTRODES:
marked with a polarity on the packing.
Connect the electrode holder in accordance
with this marking to the plus or minus sockets
of the machine.
Gas connection
Connect the gas hose (6) to the gas system by
means of a gas pressure reducer with flow
control. Fit and secure the gas hose to the gas
connection (7) on the front of the machine.
Usage of the machine
When
welding,
a
heating
components of the machine takes place and
during breaks these components will cool
down again. It must be ensured that the flow is
not reduced or stopped.
When the machine is set for higher welding
currents, there will be a need for periods
during which the machine can cool down.
The length of these periods depends on the
current setting, and the machine should not be
switched off in the meantime.
If the periods for cooling down during use of
the machine are not sufficiently long, the over-
heating protection will automatically stop the
welding process and the yellow LED in the
front panel will come on. The yellow LED
switches off when the machine has cooled
down sufficiently and is ready for welding.
Connection of electrode holder for MMA
The electrode holder and return current cable
Electrodes
are
are connected to plus tap (4) and minus tap (3).
Observe the instructions from the electrode
supplier when selecting polarity.
