Special, non-latched with superpulse
For machine versions with pulsed arc welding procedures 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
for the time t
start
).
• Slope on main program P
A
.
• 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.
• Slope to end program P
END
for the time t
end
.
• WF motor stops.
• Arc is extinguished after the pre-selected wire burn-back time elapses.
• Gas post-flow time elapses.
