OPERATING MANUAL
4. OPERATION
4.1 Loading the ller wire
4.1.1 Mounting and locking the wire spool
LOCKED OPEN
• Release locking nails of wire spool hub by
turning locking knob a quarter round.
• Mount the spool at its place. Note rotating
direction of spool!
• Lock the spool with locking knob, locking nails
of hub remain to outside position and will lock
the spool.
4.1.2 Adjusting the spool brake
Brake force is adjusted through the hole behind the
locking clip. Remove the locking clip by hand, and adjust
the tension and pressure to the friction pads mounted
inside with a screw driver. See diagram and location A.
A
The load applied varies depending on the size and weight
of the ller wire and spool, but also on the wire feed
speed. The heavier the wire spool and the faster the feed
speed, the greater the need to increase the braking load.
Adjust the pressure, secure the locking clip, set the wire
feed speed and check that the braking force is enough
to ensure the ller wire does not spill from the spool on
overrun.
Too much or unnecessary loads can impact welding
quality, load and wear to the wire feed system.
4.1.3 Adjusting the pressure arms
Adjust the drive pressure to the ller wire with the thumb
screws mounted over the pressure arms. Notice the graduated scales indicating load. The load applied should be
sucient to overcome a light braking force applied by
hand to the ller wire, as it exits the welding gun contact
tip.
For smaller diameter and soft ller wires, less feed pressure is required. It should be possible to apply a light
breaking force to the ller wire by hand, as it exits the gun
contact tip. But slightly more wire ow restriction should
render the drives rolls to slip slightly over the ller wire
without deforming the wire.
Excessive pressure causes attening of the ller wire
and damage to coated or cored ller wires. It also causes
undue wear of the feed rolls and increases gearbox load, so
reducing service life.

X3 MIG Welder© Kemppi Oy 2018 1814
OPERATING MANUAL
4.1.4 Feeding the filler wire
Ensure that the groove of the feed roll matches the diameter of ller wire used. Release
the wire end from the spool and cut o any deformed section. Be careful the wire does
not spill from the spool sides
1. Connect the welding gun and tighten the collar.
2. Straighten about 20 cm of ller wire and ensure the tip has no sharp edges. File if
necessary, as a sharp wire edge may damage the wire gun liner – particularly softer
plastic liners.
3. Present the ller wire tip to the back of the wire feed rolls and press the wire inch
switch on the wire feed panel. Feed the wire to the gun contact tip and prepare to
weld.
4. Press the Wire Inch button and allow the ller wire to feed through the gun cable to
the contact tip.
