Welding Gas Connection; Water Cooler Connection (Fig.11) (Optional Arrangement); Foot Pedal Connection; Instructions Of Use - Helvi COMPACT 220AC/DC Manual De Instrucciones

• The power cable contains power voltage
(230 Vac); it therefore must be periodically
inspected and replaced when deteriorated.
Warning: The yellow/green cable must
be fixed to the earth pin. In case of power
cable ruptures this has to be the last one
to yield. This will ensure that the genera-
tor is grounded.

WELDING GAS CONNECTION

The protection gas of the electric arc on these
generators is only used during welding with
infusible electrode (TIG). It is not required du-
ring welding with coated electrodes (MMA).
Warning: The gas cylinder must be fixed
in place with a safety belt.
• Do not forget to slightly open and then close
the tap of the cylinder to eliminate any impu-
rities.
• Assemble the pressure regulator on the
cylinder, after making sure that the gas flow
regulation knob is loose.
• Make sure the connector is tightened before
opening the cylinder tap.
• Assemble the connection on the gas tube of
the generator and the gas tube to the exit of
the pressure regulator.
• Slowly open the cylinder tap. During wel-
ding, gas flow is a function of the parameters
and accessories of the welding. The regula-
tion range is normally between 5 and 15 liters
per meter.
Note: Additional information on how to work
safely with gas, please carefully read the
PROTECTION GAS paragraph of this docu-
ment.
WATER COOLER CONNECTION (FIG.11)
(optional arrangement)
• Locate the plate
for the water cooler
connection inside
the generator, on
the bottom back
left side.
• Connect the po-
wer cable and the
pressostat cable as
shown in the label
affixed close to the
connection plate.

FOOT PEDAL CONNECTION

• Connect the foot pedal 14 pin plug to the
rear panel of the machine into socket B.
• To activate the foot pedal select button 8
on the front panel of the machine. As soon as
the remote control is activated on the pedal,
the machine can work only in 2T mode. The
arc striking is done pressing on the pedal.
Current adjustment is done using the pedal,
from its minimum value to Iw that was preset
on the front panel before activating the remo-
te control.
