Wirefeeder Controls on Inside Panel
Pre Gas Control
Sets the time period of gas flow from gun
switch on until welding commences, and
can be set for 0 – 2 seconds.
Post Gas Control
This sets the time period of gas flow
after welding ceases, and can be set for
0 – 2 seconds.
Spot Time Control
When the setting is other than fully anti
clockwise, the welder will operate for a
short time after each trigger press. Turn
clockwise to increase the weld duration
up to a maximum of 5 seconds.
Burnback Control
This control sets the time period that
welding voltage continues after the gun
switch is released, and wirefeed ceases.
The extra time allows the wire to “burn
back” slightly toward the tip.
When set correctly ‘Burnback’
prevents the welding wire freezing
in the weld pool at the end of a weld.
