Burnback time
Burnback time is a delay between the time when the wire starts to decelerate and when
the power unit switches off the welding current. Too short a burnback time results in
long filler wir e stickout, with a r isk of the wire being caught in the solidifying weld pool.
Too long a burnback time results in a shorter stickout, with increased risk of the arc
striking back to the contact tip.
Gas post--flow
Gas post--flow is the time during which the shielding gas continues to flow after the arc
has gone out.
Voltage
Higher voltage increases the arc length and produces a hotter, wider weld pool.
Irrespective of which menu is displayed, the setting value for the voltage can be
changed. The value is only displayed in the main menu.
Wire feed sp eed
This sets the required feed speed of the filler wire in inch/minute.
Irrespective of which menu is displayed, the setting value for the wire feed speed can b e
changed. The value is only displayed in the main menu.
