5.4.1 SELECTION OF START TYPE
Some wire types and sizes may be easier to start weld-
ing if the wire feed speed is kept slow until a welding
arc is established. This start method is called "slow
run-in" and may be selected when SEL START TYPE
appears. The other selection is "normal". This gives
starts with the wire feed speed used during welding.
Refer to Table 5-7 for SEL START TYPE guidance.
5.4.2 SETTING BURNBACK TIME
The burnback time makes it possible to control the
length of wire protruding out from the torch after the
weld is stopped. If the wire length is too short and
tends to burn up into the contact tip, the burnback time
must be decreased. If the wire is too long and tends to
stick to the weld pool, the burnback time must be in-
creased. Refer to Table 5-7 for burnback time adjust-
ments.
