Step 1
•
Robot issues the start signal to the power source.
•
Shielding gas is expelled (gas pre-flows).
•
Wire feed motor runs at “creep speed”.
•
Arc ignites after
the wire electrode makes contact with the workpiece; welding current flows.
•
Changeover to pre-selected wire speed (main program P
A
).
Step 2
•
Robot issues the stop signal to the power source.
•
WF motor stops.
•
Arc is extinguished after the pre-selected wire burn-back time elapses.
•
Gas post-flow time elapses.
