State

IDLE

Ready to weld.

1) Trigger On

Output: Off
Wire: Off
Gas: Off

PREFLOW

Gas purge before welding.

1) Preflow Timer
2) Trigger Off

Output: Off
Wire: Off
Gas: On

STRIKE

Allow arc to establish. This is a Non-synergic state where
Strike Speed is set independently of strike workpoint.

1) Arc Established
2) Strike Timer
3) Trigger Off

Output: On
Wire: On
Gas: On

START

Allow process to stabilize following initial arc
establishment and prior to steady state.

1) Start Timer
2) Trigger Off
3) Arc Out

Output: On
Wire: On
Gas: On

UPSLOPE

Welding parameters are ramped (linearly) to their steady
state welding (WELD) values.

1) Upslope Timer
2) Trigger Off
3) Arc Out

Output: On
Wire: On
Gas: On

WELD

Steady welding state.

1) Trigger Off
2) Arc Out

Output: On
Wire: On
Gas: On

DOWNSLOPE

Welding parameters are ramped (linearly) from their
steady state welding values to arc ending values.

1) Downslope Timer
2) Trigger On
3) Arc Out

Output: On
Wire: On
Gas: On

CRATER

Allows the welding crater to be “filled”.

1) Crater Timer
2) Trigger On
3) Arc Out

Output: On
Wire: On
Gas: On

BURNBACK

Allows for proper wire stick out following a weld.

1) Burnback Timer
2) Trigger On
3) Arc Out

Output: On
Wire: Off
Gas: On

POSTFLOW

Gas purge after welding.

1) Postflow Timer
2) Trigger On

Output: Off
Wire: Off
Gas: On

RESTRIKE

Allows the arc to re-establish if extinguished
unexpectedly during the weld. This is a Non-synergic
state where “Restrike Speed” is set independently of
strike workpoint.

1) Arc Established
2) Restrike Timer
3) Trigger Off

Output: On
Wire: On
Gas: On
