Mma Welding; Mma Welding With Front B; Mma Welding With Front A - Helvi MULTITECH 365 Manuel D'instructions

In STICK/MMA Welding (SMAW), for the connection
of the ground cable connector check for correct
polarity for the electrode you are going to use, refer
to the information on its box.
Most of the electrodes requires to connect the ground
cable on the negative (minus) connector -
connect the electrode holder on the positive (plus) -
-. Positive connectors are allocated on the generator
and also on wire feeder, you can use both but just
one at time.
