POWER FEED™ 25M
2 STEP - 4 STEP - TRIGGER OPERATION
(For Code 11313)
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 trigger. 4 Step trigger operation
provides 'trigger interlock' capability
and gives the ability to control the
amount of time spent in the arc start
and arc crater steps.
Place the toggle switch in the UP posi-
tion for 4 Step operation and in the
DOWN position for 2 Step operation.
The 2 Step - 4 Step trigger has no effect when weld-
ing with SMAW or CAG procedures.
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.
2-STEP
4 STEP
2- STEP 4- STEP- TRIGGER OPERATION
Code 11456 and higher:
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 interlock'
capability and gives the ability to control the amount of
time spent in the arc start and arc crater steps.
Press the 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 or CAG procedures.
