Safety contact switch
Gasflow control and burnback time
A = Controlling gas flow.
B = Gas flow meter
C = Setting burnback time.
Burnback time is a delay between the time
when the wire starts to brake until the time
when the power source switches off the
welding voltage. Too short burnback time
results in a long wire stickout after completion
of welding, with a risk of the wire being caught
in the solidifying weld pool. Too long burnback
time results in a shorter stickout, with
increased risk of the arc striking back to the contact tip.
Gas flushing
Gas flushing is used when measuring the gas flow or to flush any air or moisture
from the gas hoses before welding starts. Gas flushing occurs for as long as the
toggle switch is held depressed and occurs without voltage or wire feed starting.
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 toggle switch is depressed.
2 stroke
With 2-stroke gasflow starts when the welding gun trigger switch is pressed. The
welding process then starts. Releasing the trigger switch stops welding entirely and
starts burn back time (if selected).
4 stroke
With 4 stroke, the gas flow starts when the welding gun 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 and burn back time (if selected) stops when
the switch is released.

0 Welding OFF
1 Welding ON
Heat ON (accessory) and welding OFF
The bobbin area is heated so that the welding
wire is not damp when welding .
