Setting the wire feed pressure
Start by making sure that the wire moves smoothly through the wire guide. Then
set the pressure of the wire feeder’s pressure rollers. It is important that the
pressure is not too great.
Fig 1 Fig 2
To check that the feed pressure is set correctly, you can feed out the wire against
an insolated object, e.g. a piece of wood.
When you hold the pistol approx. 5 mm from the piece of wood (fig. 1) the feed
rollers should slip.
If you hold the pistol approx. 50 mm from the piece of wood, the wire should be
fed out and bend (fig. 2).
7 MAINTENANCE
Note:
All warranty undertakings given b y the supplier cease to apply if the customer
attempts to rectify any faults on the machine during the warranty period.
Regularly maintenance is important for reliable 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.
S Note that an excessive pressure setting can result in abnormal wear on the pres-
sure roller, feed roller and wire liner.

readjustment is required, follow the instructions
below. Adjust the brake hub so that wire is slightly
slack when wire feed stops.
S Adjusting the braking torque:
S Turn the red handle to the locked position.
S Insert a screwdriver into the springs in the hub.
Turn the springs clockwise to reduce the braking torque
Turn the springs anticlockwise to increase the braking torque. NB: Turn both
springs through the same amount.
