Table4-4-1: Sub-menu parameter for MIG/P-MIG
Note!
P11-P14 is available on double pulse function; P20-P21 is available on twin wire
welding mode.
- P01 Burn back time
If too long time, the wire will burn back too much with too large melting ball at the end of
wire; if too short time,the wire will stick with the workpiece.
- P02 Slow wire feeding
With too quick feeding speed, the wire will be easily exploding with failed arc-starting; if
the feeding speed is slower than the melting speed, the long arc will cause conductive tip
burned.
- P03 Gas pre-flow time
Longer time will cause waste of gas and low efficiency; shorter time will cause air hole
during arc-starting.
- P04 Gas post-flow time
Longer time will cause waste of gas; shorter time will cause air hole during crater filler
period.
- P05 Initial period
Special 4-step mode and set the percentage between initial period and pre-set
parameters. When adjust the initial period, press F2 and then adjust dial (1), make
correction of the arc length of the initial period. Press F2 again to exit.
- P06 Crater filler period
4-sept or special 4-stepmode, set the percentage between crater filler period and preset
parameters. When adjust the crater filler, press F2 and then adjust dial (1), make
correction of arc length of the crater filler. Press F2 again to exit.
- P07 Transition period
During the special 4-step mode, the time cost from starting current to normal welding
