Start interval welding

Press and hold torch trigger

• Shielding gas is expelled

• Wire feed motor runs at “creep speed”.

• Arc ignites after the wire electrode makes contact with the workpiece, welding current flows.

•

• Wire-feed motor stops after set pulse time expires.

• Arc is extinguished after the set wire burn-back time elapses.

• After the pre-selected pause time elapses, the welding operation is re-started with wire creep.

This welding procedure (interval) is repeated until the torch trigger is released.

Ending interval welding

Release torch trigger during welding phase:

• Release torch trigger.

• Wire-feed motor stops.

• Arc is extinguished after the set wire burn-back time elapses.

• Gas post-flow time elapses.

Release torch trigger during the pause phase:

• Release torch trigger.

• Gas post-flow time elapses.
