4-4 Adjustment of welding current
(1) Adjust welding current with the welding current regulator.
[Caution] : If two different welders are run simultaneously as connected to a common base metal in
different polarity, the voltage between holders rises to a level produced by addition of
voltages from two welders and electric shock may arise. Therefore, such a situation that
one worker holds two holders of two different welders should be avoided absolutely.
[Caution]
: When a common base metal is welded in different polarity using two different welders, make
sure to separately connect grounding cables on the base metal side. If a common
grounding cable is used and if its grounding is incomplete, troubles may arise to welders.
(2) The current regulating range is as indicated below. Select a current value that is appropriate for the
work contents.
Applicable electrode
Current range 30-185 A
Welding electrode Ø2.0-Ø4.0
(3) Arc force regurator
This machine is equipped with an “ Arc force regurator ” , the welding characteristic can be sdjusted
with the function. It ‘s useful when you want to change welding characteristic for peculiar welding.
(a) HARD
Its short circuit current is about 100A added welding currnet. It’s easy to start arc and the power
of arc strong in this mode. Particulary it’s suitable for welding with high cellulostic welding rod.
[NOTE] : As it’s short circuit current is restricted by a limited circuit to to protect circuit board . The
maximum short circuit current is approx. 230A.
(b) STANDARD
Its short circuit current is about 50A added welding current. It’s easy to start arc and the stability
of arc is superior in this mode. It’s suitable for many kinds of weliding rod.
(c) SOFT
Its short circuit current is almost same as large as the welding current. The arc is stable in this
mode by its stable cyrrent characteristic.
