WARNING!
Arc welding and cutting can be injurious to yourself and others. Take precautions
when welding and cutting.
ELECTRIC SHOCK - Can kill
•Install and ground the unit in accordance with instruction manual.
•Do not touch live electrical parts or electrodes with bare skin, wet gloves or
wet clothing.
•Insulate yourself from work and ground.

•Welders should use the following procedures to minimize exposure to
EMF:
○ Route the electrode and work cables together on the same side of
your body. Secure them with tape when possible. Do not place your
body between the torch and work cables. Never coil the torch or
work cable around your body. Keep welding power source and
cables as far away from your body as possible.
○ Connect the work cable to the workpiece as close as possible to the
area being welded.
FUMES AND GASES - Can be dangerous to health
•Keep your head out of the fumes.
•Use ventilation, extraction at the arc, or both, to take fumes and gases
away from your breathing zone and the general area.
ARC RAYS - Can injure eyes and burn skin

5.1Fitting the liner
Fit the correct wire guide liner for the application, as needed to suit the wire type and
diameter. See chapter "MAINTENANCE" section "Spiral liner / PTFE liner".
NOTE!
For information on how to install new liners and about correct assembly
procedure, see the chapter entitled “Maintenance”
Spiral liner = for steel wires
PTFE−liner = for aluminium, copper, nickel and stainless steel wires
5.2Assembling the swan neck
The following figures indicate how to assemble the different welding torch types.
Regular maintenance is important for safe and reliable operation.
Welding torch
Cleaning and replacement of the welding torch’s wear parts should take place at regular
intervals in order to achieve trouble−free wire feed. Blow the wire guide clean regularly and
clean the contact tip.

servicing the equipment.
6.2Cable assembly
Check that all the nuts are tight.
Replace the liner if it is worn or dirty.
Replace damaged, deformed or worn parts.
6.3Cleaning the wire feed
Disconnect the torch cable assembly from the equipment and lay it out straight.
Unscrew the nut and pull out the wire guide liner. Remove other parts from the swan neck.
Blow compressed air through the wire conduit from both ends in order to remove wire
shavings.
Insert the liner into the wire conduit and screw the nut back on.
NOTE!
New liners must be cut to the correct length. Follow the following tips and
suggestions:
6.4Spiral liner / PTFE liner
1.Unscrew all the fittings from the swan neck.
2.Unscrew the union nut on the central plug.
3.Remove the old liner, and then push the guide spiral liner through the hose as far as it
will go.
Make sure the cable is stretched out more or less straight.
4.Tighten the union nut by hand.
5.Cut the overhang off the spiral at the swan neck and remove the guide spiral liner
again.
6.For a smooth transition to the contact tip, grind the end of the spiral to an angle of
approx. 40°. Deburr the cutting edge.
7.Push the sharpened guide spiral liner through the hose to the holder nipple.
