WELDING CURRENT REGULATOR
Position welding current adjusting knob
(T) in correspondance of the chasen
current value, so as
necessary amperage, taking into acount
the diameter and the type of the electrode.
For technical data see page M52
SWITCH REDUCTION SCALE
For small electrodes (up to Ø 3.25-130A
and 4-200A) it is recommended to use the
reduction
accurate regulation of the welding current (lever
position at 200A).
When using electrodes of a diameter greater than 3.25 and/
or 4 set the welding scale knob to max. position.
ARC FORCE SELECTOR
This welder is equipped with base current
for improved welding with cellulose
electrodes. The base current functions
when the arc force selector is turned on.
Remote control connection
The optional PHG1 remote control is used to control the
current or voltage at a distance. When the switch is "ON"
(pointing toward the remote control connector), the current/
voltage is regulated by the remote control. When the switch is
"OFF" the current/voltage is regulated by the front panel
potentiometer.

Welding cable connections
For direct current electrode positive, connect work cable to
negative (-) terminal and electrode holder to positive (+)
terminal. For direct current electrode negative, reverse cable
connections.

Make sure that the ground clamp makes a good connection
and is near the welding posítion.

Auxiliary power outlets and thermal circuit
breaker
The unit is equipped with 4 auxiliary output sockets – one
three phase and three single phase. The voltages depend on
the version selected. The three-phase socket requires no
protection as the asynchronous alternator protects itself. The
single-phase sockets are supplied with thermal circuit breakers.
The 32A socket and the two 16A sockets have a push button
type thermal circuit breaker that pops out when overloaded.
After it has been activated it needs a short time to cool down
out then can be re-inserted. If the thermal circuit breakers
continue to pop out check that the load is not too large for the
output of the socket.

Ground fault interrupter
The ground fault interrupter protects the operator from injury
in the event of a ground fault. If it is activated, raise the plastic
cover and push the lever up to reset.
Instruments
Standard instruments include a fuel level gauge, an operating
hour counter and a voltmeter for the auxiliary power which
shows the three phase voltage (400V). If the voltmeter does
not show any voltage check that the GFI (ground fault
interrupter) is inserted. The voltage shown will vary depending
on the load and the welding current being drawn. At no load
and when not welding, the voltage can be as high as 440V.
The auxiliary power cannot be used when it drops below
360V.
Optionally an ammeter and a voltmeter for the welding output
are available.
