2-STEP 4-STEP- TRIGGER
OPERATION
The 2-Step - 4-Step switch changes the function of
the gun trigger. 2-Step trigger operation switches the
welding output ON-OFF in direct response to the trig-
ger. 4-Step trigger operation provides 'trigger inter-
lock' capability and gives the ability to control the
amount of time spent in the arc start and arc crater
steps.
Press the right push button on the case front to toggle
between 2-Step and 4-Step operation.
The 2-Step, 4-Step trigger has no effect when weld-
ing with SMAW.
2-Step Trigger
2-Step trigger operation is the most common. When
the gun trigger is pulled, the welding system (power
source and wire feeder) cycles through the arc start-
ing sequence and into the main welding parameters.
The welding system will continue to weld as long as
the gun trigger is activated. Once the trigger is
released, the welding system cycles through the arc
ending steps
4-Step Trigger
4-Step trigger operation gives the welder additional
control in the welding sequence. 4-Step trigger allows
the welder to choose the arc start, weld and arc end
time. It may also be set-up to work as a trigger inter-
lock.
