Adjustments
Before adjusting components, pull plug from power supply.
18
20
Fine adjustment Pressure
Turn adjusting screw (23) anticlockwise to reduce the
pressure down to 30 % of the maximum welding pressure.
22
For thinner or softer materials reduce the pressure.
19
Pressure roller alignment (Drive rollers)
Loosen screw (19). By turning screws (18) you can adjust
the angle of the upper pressure roller. This adjusts the posi-
tion to the lower pressure roller. Carry out a test weld to
21
check the position is correct. The weld pressure should be
23
the same from the left side to the right side. Attention in the
relaxed position the rollers are not parallel. Adjustment is
necessary for HDPE > 0.5 mm. Tighten screw (19) to lock
the position.
Wedge position adjustment
Loosen screws (24). Place 2 pieces of the material to be
welded between the pressure rollers and close the tension
lever (6). Move the wedge with light pressure between the
material towards the pressure rollers. Wedge should be at
right angle to pressure rollers. Tighten screw (24).
25
Hold down rollers (only for geo2)
Loosen screw (21), place 2 pieces of the material to be
welded between the pressure rollers and upper and lower
hold down rollers. Close the tension lever (6). By turning
screw (20) position the upper hold down roller (21) so
24
that there is light pressure on the wedge from the upper
and lower hold down rollers (25).
Attention: For optimal welding results the material should
have maximum contact to the upper and lower side of the
wedge during the welding process.

Replacing pressure rollers (8)
Depending on welding material choose the right pressu-
re rollers (8) steel or silicone (both in combination also
possible). Unscrew locking screw-pin (26). Replace upper
and/or lower pressure rollers (8) and reinsert locking
screw-pin (26).

Attention:
Square-end of fl exible wire (27) must be inserted carefully.
