welding machine, and tighten it clockwise.
Insert the cable plug with work clamp into the "－" socket on the front panel of the welding

machine,
and tighten it clockwise
Ground connection is needed for safety purpose.
6)
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.
9.2 Operation
After being installed according to the above method, and the power switch being switched
1)
on, the machine is started with the power LED on and the fan working.
Pay attention to the polarity when connecting. Phenomena such as unstable arc, spatter,
2)
and electrode sticking could happen if improper mode is selected. Exchange the polarity
if necessary.
Switch the MMA/TIG switch to MMA, welding can be carried out with output current in
3)
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.
Select cable with larger cross-section to reduce the voltage drop if the secondary cables
4)
(welding cable and earth cable) are long.
Preset the welding current according to the type and size of the electrode, clip the
5)
electrode and then welding can be carried out by short circuit arc ignition. For welding
parameters, please refer to the below table
