13. File the tip of the filler wire smooth.
Sharp edges on the filler wire tip may damage the wire liner.
14. Guide the filler wire through the inlet tube (A) and middle wire guide tube (B) to the outlet, which feeds the filler
wire to the welding gun. Push the filler wire by hand inside the gun so that the wire reaches the wire liner (about 20
cm).
15. Close the pressure arms so that the filler wire is locked between the feed rolls. Ensure that the filler wire sits in the
feed roll grooves.
16. Lower the pressure handle on the feed rolls.
17. Adjust the pressure of the feed rolls with the pressure adjustment wheels. The pressure is the same for both feed
roll pairs.
The graduated scales on the pressure handle indicate the pressure applied to the feed rolls. Adjust the pressure of the
feed rolls according to the table below.
Filler wire material
Fe/Ss solid
Metal and flux cored
Self-shielded
Aluminium
Excessive pressure flattens the filler wire and may damage coated or cored filler wires. Excessive pressure also unne-
cessarily wears the feed rolls and increases gearbox load.
