5) INSTALLATION
5.1) Connection to a power source, feed rollers and nozzles.
1) Fix the welding cable connected to the terminal + of the power source in the
the rear panel.
2) Fix the negative clamp to the terminal power source.
3) Fix the hose of the gas pressure regulator in the connection of the solenoid input valve, in the rear of the
wire feeder, when using wires which requires gas protection.
4) Install the welding gun ( see note in section 2).
5) Install the wire.
6) Install the feed rollers according to the wire diameter to be used (see table 5.1)
TABLE 5.1
Wire diameter ( mm )
0.80 - 1.00
1.20 - 1.60
1.60 - 2.40
2.80 - 3.20
7) Install the inlet nozzle, the intermediate nozzle and the outlet nozzle according to the wire diameter
to be used (see table 5.2)

5.2) Dip switches position.
The dip switches are located on the control PCB mounted in inside upper compartment of the wire
feeder cabinet. See table for switch positions and description.

Factory Setting - Constant Current Operation
("Voltage Control Mode")
In this operation mode the Tubmatic feeder is ready for connection to a " Constant Current "
power source which typically provides a high open circuit voltage and low short circuit current
which makes arc starting difficult. Therefore, "slow run-in" of the wire is automatically enabled
if OCV exceeds 33 volts to provide good and reliable arc starting. The arc length during
welding is determined by a combination of the wire feed speed knob position (Tubmatic
feeder front panel) and the weld "Current" setting on the CC power source. When a good
welding condition is achieved, the arc length will be maintained by changes in wire feed
speed provided by arc voltage control. Variables causing changes in arc voltage, for example,
wire "stick-out", wire density or shielding variations, will cause the wire feed speed to
compensate to maintain the arc length preset.
