The number of programs (P
An
) corresponds to the cycle number specified under N cycle.
1st cycle
• 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
from P
A1
)
2nd cycle
• Release torch trigger.
• Slope to main program P
A1
.
The slope to main program P
A1
is given at the earliest after the set time t
START
elapses and at the
latest when the torch trigger is released. Tapping (pressing briefly and releasing within 0.3 sec)
can switch to other programs. Programs P
A1
to P
A9
are possible.
3rd cycle
• Press and hold torch trigger.
• Slope to end program P
END
from P
AN
. The program can be stopped at any time by pressing the torch
trigger longer than 0.3 sec. P
END
from P
AN
is then executed.
4th cycle
• Release torch trigger.
• WF motor stops.
• Arc is extinguished after the pre-selected wire burn-back time elapses.
• Gas post-flow time elapses.
Latched/special-latched tap start (P9)
In latched
– tap start – operating mode it is possible to switch straight to the second step by tapping the
torch trigger; it is not necessary for current to be flowing.
The welding can be halted by pressing the torch trigger for a second time.
"Single or dual operation" (P10) setting
If the system is fitted with two wire feeds, no further accessory components may be operated on
the 7-pole connection socket (digital)!
This relates to digital remote controls, robot interfaces, documentation interfaces, welding
torches with digital control lead connection, etc.
No second wire feed may be connected in single operation (P10 = 0)!
• Remove connections to the second wire feed
In dual operation (P10 = 1 or 2), both wire feed units must be connected and configured differently
on the controls for this operating mode!
• Configure one wire feed unit as the master (P10 = 1)
• Configure the other wire feed unit as a slave (P10 = 2)
Wire feed units with key switches (optional, - See 5.16 Protecting welding parameters from
unauthorised access chapter) must be configured as masters (P10 = 1).
The wire feed configured as the master is active after the welding machine is switched on. There
are no other functional differences between the wire feeds.
