Functions when using 4--stroke control of the welding gun
Gas pre--flow starts when the welding gun trigger switch is pressed (1): releasing the
trigger switch starts the welding process. Pressing the trigger switch again (3) starts
crater filling (if selected) and reduces the welding data to a lower va lue. Releasing the
trigger switch (4) stops welding entirely and starts gas post--flow (if selected).
TIP: Crater filling stops when the trigger switch is r e leased. Keeping it held in instead
continues crater fillin g (the dotted line).
Crater fillin g
Crater filling helps to avoid pore, thermal cracking and crater formation in the weld when
welding stops.
Inductance
Low inductance produces a harsher sound and a m ore stable concentrated arc. Higher
inductance gives a softer weld (less spatter) and a hotter process, allowing the weld
pool to flow out more.
Gas p re--flow
Gas pre--flow indicates the time during which shielding gas flows before the arc is
struck.
Slow RunIn start
Slow RunIn starting feeds out the wire at 50 % of the set speed until it makes electrical
contact with the workpiece.
