Migatronic FOCUS TIG 160 DC HP Manuel D'instruction page 13

COATED ELECTRODES: Electrodes are 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 of various 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 overheating
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 are
connected to plus tap (4) and minus tap (3).
Observe the instructions from the electrode
supplier when selecting polarity.
