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.

alternator protects itself. The single-phase sockets
are supplied with thermal circuit breakers.
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.
