Automatic cut-out

Once the f ault periods have elapsed, the automatic cut-out stops the welding process when it has been

triggered by one of two states:

• During ignition

5 s af ter the start of the welding process, no welding current flows (ignition error).

• During welding

The arc is interrupted for more than 5 s (arc interruption).

Non-latched mode

Step 1

• Press and hold torch trigger.

• Shielding gas is expelled (gas pre-flows).

• Wire f eed motor runs at "creep speed".

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

• Change over to pre-selected wire speed.

Step 2

• Release torch trigger.

• WF motor stops.

• Arc is extinguished after the preselected wire burn-back time expires.

• Gas post-flow time elapses.
