wire feed unit to be moved easily over the floor or work table.
A wire feed unit and turnable or carriage can also be fitted with a support device and
suspended over the work place.
All the settings are controlled by the PUA1 setting
box.

5.1 Termination resistance
The termination resistance must be connected to the ends of the CAN bus to prevent
communication problems.
The controller has a built--in terminator, but the power source and wire feed unit do
not.
The terminator should be fitted as follows depending on how the units are
connected:
1. Controller con n ected to wire feed unit.
The termination resistance must be con-
nected to the rear of the power source.
(Already connected this way on delivery).
2. Controller connected to power source.
The termination resistance
must be connected to the front
of the wire feed unit.
6 MAINTENANCE
Regularly maintenance is important for r eliable and safe operations.
S Cleaning and replacement of the wire feed mechanism’s wear parts should take
place periodically to ensure trouble free wire feed.
Note that an excessive pressure setting can result in abnormal wear on the pres-
sure roller, feed roller and wire liner.
S Torch
Regularly blow the wire liner and clean the gas shroud.
