1) A primary power supply cable is available for this welding machine. Connect the power supply
cable to the rated input power.
2) The primary cable should be tightly connected to the correct socket to avoid oxidization.
3) Check whether the voltage value varies in acceptable range with a multi-meter.
4) Insert the cable plug with electrode holder into the "+" socket on the front panel of the
welding machine, and tighten it clockwise.
5) Insert the cable plug with work clamp into the "－" socket on the front panel of the welding
machine, and tighten it clockwise.
6) Ground connection is needed for safety purpose.
7) The connection as mentioned above in 4) and 5) is DCEP connection. Operator can choose
DCEN connection according to workpiece and electrode application requirement. Generally,
DCEP connection is recommended for basic electrode, while there is no special requirement
for acid electrode.
Operation TIG
1) After being installed according to the above method, and the power switch being switched on,
the machine is started with the power LED on and the fan working.
2) Pay attention to the polarity when connecting. Phenomena such as unstable arc, spatter, and
electrode sticking could happen if improper mode is selected. Exchange the polarity if
necessary.
3) Switch the MMA/TIG switch to MMA, welding can be carried out with output current in rated
range. Switch the MMA/TIG switch to TIG, ignite arc and weld in lift arc mode, arc can be
ignited with lift arc ignition current in rated range, and welding can be carried out with
welding current in rated range. (See Fig.7 above.)
4) Select cable with larger cross-section to reduce the voltage drop if the secondary cables
(welding cable and earth cable) are long.
5) Preset the welding current according to the type and size of the electrode, clip the electrode
and then welding can be carried out by short circuit arc ignition. For welding parameters,
please refer to the below table.
