Function explanations

Open the lid for access to the 4 stroke/2 stroke, the Cored/Solid wire and the Creep start
functions.
2-stroke
With 2-stroke gas pre-flow (if used) starts when the welding torch trigger switch
is pressed. The welding process then starts. Releasing the trigger switch stops
welding entirely and starts gas post-flow (if selected).
4-stroke
With 4 stroke, the gas pre-flow starts when the welding torch trigger switch is
pressed in and the wire feed starts when it is released. The welding process
continues until the switch is pressed in again, the wire feed then stops and when
the switch is released the gas post-flow starts (if selected).
Wire selection – Cored wire
A constant burnback time is selected when the trigger is released to adapt to
welding with cored wire.
Wire selection – Solid wire
Short Circuit Termination (SCT) behavior is selected when the trigger is released
to adapt to welding with solid wire.
SCT is a new way to stop the welding with some small short circuits to reduce
the end crater and oxidation. It also gives the advantage of a good start
performance with solid wire.
Creep start
Creep starting feeds out the wire at 9 m/min (29.5 ft/min) until it makes electrical
contact with the workpiece.
Wire inching
Wire inching is used when one needs to feed wire without welding voltage being
applied. The wire is fed as long as the button is depressed.
Gas purging
Gas purging is used when measuring the gas flow or to flush any air or moisture
from the gas hoses before welding starts. Gas purging occurs for as long as the
button is held depressed and occurs without voltage or wire feed starting.
Wire feed speed
This sets the required feed speed of the filler wire in m/minute.
