Non-latched operation with superpulse
For machine versions with pulsed arc welding procedures only.
Figure 6-2
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.
• Start the super pulse function beginning with main program P
A
:
The welding parameters switch between main program P
A
and the reduced main program P
B
at the
specified times.
Step 2
• Robot issues the stop signal to the power source.
• Super pulse function is ended.
• Wire feed motor stops.
• Arc is extinguished after the pre-selected wire burn-back time elapses.
• Gas post-flow time elapses.
