6.
FUSE = If the machine is exposed to an excessive work load, the fuse
will blow. It can be unscrewed and replaced.
FUSE
7.
CURRENT - main current adjustment.
8.
BASE CURRENT - low current. This function acta only at switched on
pulsation It is used for switching the current between main current
(CURRENT) and low current during pulsation welding.
9.
DOWN SLOPE - automatic, stepless decrease of the electric current
intensity at the decay of the electric arc in order to avoid fusions. This
function is adjusted within "second" intervals.
10.
PULSE DUTY CYCLE = This adjusts the duty cycle of the pulsed
current.
11.
POWER SUPPLY INDICATOR - after switching on the machine, this
control lamp lights-up.

12.
PULSE FQ - this function means the frequency in time unit
(for impulse welding)
13.
PRE FLOW = Gas pre-flow time adjustable in seconds intervals.
PF
14.
PEAK CURRENT = Adjusts the height of the current peak.
15.
POST TIME - gas access time after the decay of the electric arcis
adjusted in second intervals. The adjusting function for this time value
is significant for the fused fusion weld which has to be cooled and pro-
tected against oxidation after finishing the welding process.
16.
CLEAN WD - adjustment of the positive and negative current in order
to achieve appropriate fusion penetration of the fusion weld. This func-
tion is applicable only for aluminum welding.
