5.3. MMA electrode holder and earth cable connection
(Wiring diagram)
Pay attention to the polarity of the wiring before MMA. Generally, there are two connection
methods for DC welder: DCEN and DCEP.
DCEN: The electrode holder is connected to the negative polarity, and the workpiece is
connected to the positive polarity;
DCEP: The electrode holder is connected to the positive polarity, and the workpiece is
connected to the negative polarity.
The operator can also choose the DCEN according to the base metal and electrode type
being used. Generally speaking, it is recommended to adopt DCEP for basic electrode (i.e.,
welding electrode connected to the positive polarity), while no special provisions are made
for acid electrode.
1) Ensure that the welder power switch is turned off.
2) Insert the cable plug with electrode holder into the corresponding socket on the front
panel of the welder and tighten it clockwise.
3) Insert the cable plug with earth clamp into the corresponding socket on the front panel of
