Start
Two alternatives can be chosen: Direct start or Scratch start .
S
Direct start means that travel starts when the arc ignites.
S
Scratch start means that travel starts at the same time as wire feed. Scrape
start is used when welding rusty or dirty material.
STOP WELDING
Crater fill
and Burnback time can be set.
Crater fill times between 10 and 3000 ms (0.01 -- 3 sec.) can be selected.
The crater fill function is used to finish the weld without leaving a crater. Crater fill
starts when the welding stop key is pressed, and continues for the preset crater
fill time. This function is most useful when MIG/MAG welding.
Burnback times between 10 and 3000 ms (0.01 -- 3 sec.) can be selected.
The burnback time starts after the crater fill sequence has ended. Correct choice of
the burnback time prevents:
-- the wire sticking to the work piece
-- the wire sticking to the nozzle
