The benefits of pulse welding is the ability to control the weld pool and amount of heat absorbed by
work resulting in a smaller heat affected zone which results in fewer deformations and reduced chance
of cracking. There are no set rules for pulse welding as this is down to personal choice by the welder.

Welding in STICK MMA (SMAW) Mode
1
Fit MMA electrode holder to machine
2
Fit earth lead to machine and to work piece
3.
Select MMA on MMA/TIG switch
4.
Place electrode in holder
5.
Select desired welding base current
6.
Strike arc and weld
WARNING!
ELECTRIC SHOCK CAN KILL
When machine is switched to MMA mode, output terminals are always live, take care and do not touch
electrode and earth by person at same time, otherwise electric shock will occur.
The foot pedal has no affect on welding current in MMA mode and the gas flow and high frequency
starting circuit is disabled.
