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.
The connection as mentioned above in 6.1(4) and 6.1(5)is DCEP connection.
Operator can choose DCEN connection according to work piece and
electrode application requirement. Generally, DCEP connection
is recommended for basic electrode, while there is no special requirement
for acid electrode.
5.2 OPERATION METHOD
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) Select cable with larger cross-section to reduce the voltage drop if the
secondary cables (welding cable and earth cable) are long
4) 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 starting. For welding parameters, please refer to 6.3
