Function explanations
Open the lid for access to the 2-4 stroke and the creep start functions.
2 stroke
With 2 stroke, wire feed starts when the trigger switch is pressed in and ends when
it is released.
4 stroke
With 4 stroke, the gas flow starts when the 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, then the wire feed stops, and when the switch is released the gas
stops flowing.
Creep start
Creep start when activated, means that the wire is fed at low speed (1.5 m/min) until
it comes into electrical contact with the workpiece, or 3 sec. has elapsed after which
the speed increases to the set speed.
Burnback time
Burnback time is not an adjustable delay. This is the time from when the wire starts
to brake until the time when the power source switches off the welding power.
Wire inching
Wire inching is used when you need to feed wire without welding voltage being
applied. The wire is fed with a fixed speed of 29.5 ft/min (9 m/min) as long as the
switch is held to the left.
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
switch is held to the right and occurs without voltage or wire feed starting.
Wire feed speed
This sets the required feed speed of the filler wire in m/minute or in inch/minute.
