Adjustable arcforcing :
Shortly before the electrode threatens to stick, the arcforcing device sets
an increased current designed to prevent the electrode from sticking. The
value of the current increase depends on the setting of the arcforce
potentiometer. Excellent welding results are achieved with all difficult types
of electrode by arcforcing.
"Far left" position:
Low arcforcing
Þ
smoother arc,
low current increase before the short-
circuit. Used with stick electrodes
enveloped with rutile.
"Centre" position:
Medium arcforcing
Þ
normal arc,
medium current increase before the
Short-circuit. Used for alkaline coated
stick electrodes.
"Far right" position:
High arcforcing
Þ
hard arc,
high current increase before the short-
circuit. Used with cellulose stick electrodes.
Functional specification Antistick:
If the stick electrode sticks in spite of the arcforcing device, the machine
automatically switches over to the minimum current within about 1 sec, so
that the annealment of the electrode is prevented.
If the antistick device has responded, check the welding current setting and
if necessary correct it.
