Wire selection – Cored wire
A constant burnback time is selected when the trigger is released, to adjust to
welding with cored wire.
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 takes place for as long as
the button is held depressed and takes place without voltage or wire feed
starting.
Wire inching
Wire inching is used when feeding wire without applying a welding voltage. The
wire is fed as long as the button is depressed.
2-stroke
With 2-stroke, gas pre-flow 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.
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, when the switch is released the
wire feed then stops the gas post-flow starts.
Voltage
Higher voltage increases the arc length and produces a hotter, wider arc.
Wire feed speed
This sets the required feed speed of the filler wire in inch/minute or m/minute.
5.3 Wire feed pressure
Start by making sure that the wire moves smoothly through the wire guide. Then set the
pressure of the wire feeder's pressure rollers. It is important that the pressure is not too high.
