Step 1
• Press and hold torch trigger
• 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
)
Step 2
• Release torch trigger
• Slope to main program P
A
.
The slope on main program P
A
is given at the earliest after the set time t
START
elapses and at the
latest when the torch trigger is released.
Tapping
1)
can be used to change over to the reduced main program P
B
.
Repeated tapping will switch back to the main program P
A
.
Step 3
• Press and hold torch trigger
• Slope to end program P
END
.
Step 4
• Release torch trigger
• WF motor stops.
• Arc is extinguished after the preselected wire burn-back time expires.
• Gas post-flow time elapses.
1)
Prevent tapping (brief press and release within 0.3 seconds)
If the welding current is to be prevented from switching over to the reduced main program P
B
by
tapping, the parameter value for WF3 needs to be set to 100% (P
A
= P
B
) in the program sequence.
