Pulse arc welding machines only.
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 is flowing (start
program P
START
•
Slope on main program P
•
Start the super pulse function beginning with main program P
The welding parameters switch between main program P
specified times.
Step 2
•
Robot issues the stop signal to the power source.
•
Super pulse function is ended.
•
Slope to end program P
•
WF motor stops.
•
Arc is extinguished after the pre-selected wire burn-back time elapses.
•
Gas post-flow time elapses.
