Gas Connection
A gas cylinder must be installed with a proper flow
regulator. Once a gas cylinder with a flow regulator has
been securely installed, connect the gas hose from the
regulator to the machine
WARNING
The welding machine supports all suitable shielding
gases including carbon dioxide, argon and helium at a
maximum pressure of 5,0 bars.
WARNING
Always fasten gas cylinder properly in vertical position in
a special holder on the wall or on a carriage. Remember
to close gas cylinder valve after having finished welding.
WARNING
Gas cylinder can be fasten on the machine's shelf, but
the height of gas cylinder doesn't have to be higher than
43in/1,1m. The gas cylinder which is fastened on the
machine's shelf has to be secured by attaching it to the
machine using the chain.

necessary.

Check condition and operation of the cooling fan.
Keep clean its airflow slots.
Periodic maintenance (every 200 working hours
but at least once a year)
Perform the routine maintenance and, in addition:

Keep the machine clean. Using a dry (and low
pressure) airflow, remove the dust from the external
case and from the cabinet inside.

If it is required, clean and tighten all weld terminals.
The frequency of the maintenance operations may vary
in accordance with the working environment where the
machine is placed.
Do not touch electrically live parts.
Before the case of machine will be removed, the
