5.2. MMA
5.2.1. Installation
1)
Insert the cable plug with electrode holder into the “+” socket on the front panel of the welding machine,
and tighten it clockwise.
2)
Insert the cable plug with work clamp into the “
－
” socket on the front panel of the welding machine, and
tighten it clockwise.
3)
Ground connection is needed for safety purpose.
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.

5.2.3. Operation
Pay attention to the connection polarity. Generally, DCEP and DCEN are available in DC MMA.
DCEP: Connect the electrode holder to “+” output terminal, and the work clamp to “-” output terminal.
DCEN: Connect the electrode holder to “-” output terminal, and the work clamp to “+” output terminal.
Operators may choose connection mode according to workpiece and electrode application requirement. Phenomena
such as unstable arc, excessive spatter, and electrode sticking will occur when improper connection mode is selected.
Change the polarity by exchanging the quick connectors to solve the problem.
Anti-sticking function is available for this machine.
Select MMA mode by pressing the welding mode selecting key, and MMA can be carries out. There is voltage output
at both output terminals.
