9.4. Lift TIG operation.
9.4.1 Connect Earth Lead Quick Connector (23) to the positive (+) output welding terminal (6).
9.4.2 Connect Earth Clamp (22) to the work piece. Contact
with workpiece must be strong contact with clean, bare
metal, with no corrosion, paint or scale at the contact
point.
9.4.3 Connect the TIG torch power lead to the negative (-)
welding output terminal (11).
9.4.4 Connect the gas supply to the TIG torch.
9.4.5 Turn the machine on at the Mains Power Switch
9.4.6 Press the Left button to mode selection,
9.4.8 When welding the display will change to show actual
welding volts and amperage.
10. MAINTENANCE.
10.1 Disconnect input plug or power before maintenance or
repair on machine.
10.2 Be sure input ground wire is properly connected to a
ground terminal.
10.3 Check whether the inner gas-electricity connection is
well (esp. the plugs), and tighten the loose connection; if
there is oxidization, remove it with sand paper and then re-
connect.
10.4 Keep hands, hair, loose clothing, and tools away from
electrical parts such as fans, wires when the machine is
switched on.
10.5 Clear the dust at regular intervals with clean and dry
compressed air; if the working condition is with heavy smoke
and air pollution, the welding machine should be cleaned
daily.
10.6 The compressed air should be reduced to the required
pressure lest the little parts in the welding machine be
damaged.
10.7 To avoid water and rain, if there is, dry it in time, and
check the insulation with mega-meter (including that
between the connection and that between the case and the
connection). Only when there is no abnormal phenomenon
should the welding continue.
10.8 If the machine is not used for a long time, put it into the
original packing in dry condition.
