5 INSTALLATION
The installation must be carried out by a professional.
CAUTION
This product is intended for industrial use. In a domestic environment this product may
cause radio interference. It is the user's responsibility to take adequate precautions.
5.1 Connections
S Connect the welding gun to the feed unit's EURO connection.
S Connect the red water hose to the red-marked quick coupling and the blue water
hose to the blue-marked quick connection on the wire feed unit/power source.
S Lubricate the O-ring on the gas nipple in the central connector so that the O-ring
is properly positioned and prevents any gas leakage.
S Connect the welding gun's control contact to the feed unit/power source's
23-pole Burndy socket.
Certain wire feed units/power sources (e.g. AristoFeed or ESABMig C420) require a
connection kit to be installed in the feed unit/power source (see relevant instruction
manual and accessories on page 16.)
The welding current is totally dependent on and regulated by the wire feed speed.
The potentiometer for the wire feed speed is mounted on the welding gun handle. To
regulate the wire feed speed, turn the potentiometer clockwise, which increases the
feed speed.
Three versions of the welding gun feed rollers are available for the following wire
diameters: 0.8, 1.0 and 1.2 mm.
When choosing contact tip, see separate table on page 16.
