Danger! Unplug the tool before opening it, as live compo-
nents and connections are exposed.
Incorrect use of hot air tools can present a fire and explo-
sion hazard, particularly in the proximity of flammable
materials and explosive gases.
The tool must be operated under supervision.
Heat can ignite flammable materials which are not in view.
For personal protection, we strongly recommend the tool
to be connected to an RCCB (Residual Current Circuit
Breaker) before using it on construction sites.
The rated voltage stated on the tool must correspond with
the mains voltage.
Danger of getting burned! Do not touch the end of the
heater tube and nozzle when they are hot. Let the tool
cool down. Do not point the hot air flow in the direction of
people or animals.
Protect the tool from damp and wet.

WARNING
CAUTION
Connect tool to a receptacle with protective earth terminal.
Any disconnection of the protective conductor in or outsi-
de the tool is dangerous!
Only use extension lead with protective conductor.
Laser radiation! Do not look into the beam, Laser Class 2.

Drive/pressure roller
•Drive speed → continuously adjustable and electronically controlled. The
control circuit is configured such that the desired welding speed remains
constant during any voltage fluctuations. The drive/pressure roller (8) is
configured as a pendulum roller.
•Welding pressure → the welding pressure is brought to bear on the material
by means of the machine’s weight and the extra weight (3) via the
drive/pressure roller (8).
•Heating system → the hot wedge temperature is continuously adjustable and
electronically controlled. Depending on the material, the hot wedge position
can be sent to any required horizontal position.

Hot wedge welding position
•Depending on the material thickness, pre-adjust the position of the hot wedge
(6) in relation to the drive/pressure roller (8) in accordance with Fig 2, Page 4.
•Procedure
– Loosen fixing screw (20)
– Using adjusting screw (21), adjust the position of the hot wedge in relation to
the drive/pressure roller. (One complete turn = 1.25 mm)
– Push holding arm (15) up to the stop in the direction of the hot wedge.
– Tighten fixing screw (20).
-Tracking correction of the drive/pressure roller
•Tracking control should be carried out using the track
adjustment screw (22), see functional directions on the
lifting device (12).
•Carry out test run.

WELDING LEISTER Uniplan Wedge
Weld preparation
•Spread the weld material on a clean and level surface.
•The material to be welded must be dry and clean between the overlaps.
•The overlap width should be set as follows:
– Heating wedge 20 mm = overlap width 23 mm
– Heating wedge 30 mm = overlap width 31 mm
•The material must be stretched out tightly and fixed.
Preparing for use
•Hook extra weight (3) onto base plate (4).
•Swing hot wedge (6) upwards using swivel lever (19) and engage, (Fig. A).
•Set guide roller (25) to position "Inaktiv" (inactive) by means of guide roller
knob (24) and guide roller lever (23), (Fig. B).
•Operate lifting device (12) by means of lifting device lever (18) so that
drive/pressure roller (8) and drive roller (10) are at no-load, (Fig. C).
•Raise pinch roller (9), (Fig. D).
•Drive/pressure roller (8) should be positioned parallel to the edge of guide
roller (25). See Page 5 for drive/pressure roller (8) track correction.
•Connect tool to mains. Mains voltage must correspond with tool voltage.
•Switch tool on using main switch (16).
•The upper and lower surfaces of the hot wedge (6)
must be cleaned after each weld run, using a fine
brass wire brush (Fig. E)

OPERATION LEISTER Uniplan Wedge

Tool positioning
•Place automatic welder onto the overlap of material to be welded.
•Guide cover (26) or laser guide (optional extra) should be lined up with over-
lap edge of the material to be welded (Fig. E).
•Drive/pressure roller (8) should protrude over overlap edge of the material to
be welded by about 2 mm (Fig. E).
•If welding takes place with guide roller (25) in position, then set guide roller
lever (23) to "aktiv" (active) and engage (Fig. F).
•Operate lifting device (12) by means of lifting device lever (18) so that the
automatic welder is ready to move (Fig. G).

Welding process
•Set welding parameters, see Pages 4 and 5.
• Allow welding temperature to be reached, Display 3, see Page 6.
•Position hot wedge (6) using swivel lever (19) between the materials to be wel-
ded (Fig. H).
The welding process will start automatically via automatic drive.
•Carry out test weld in accordance with the material manufacturer's welding
instructions and national guidelines or regulations.
•Check welding process. If necessary, correct welding parameters, see Pages
4 and 5.
•After weld run, swing hot wedge (6) out and up to the stop using swivel lever
(19), raise up and engage (Fig. A).
The welding process will stop automatically.
•Operate the lifting device (12) by means of lifting device lever (18) so that
drive/pressure roller (8) and drive roller (10) are at no-load (Fig. C).
• The upper and lower surfaces of the hot wedge (6) must be cleaned after
each weld run, using a fine brass wire brush (Fig. E).
•Switch off tool at main switch (16).
•Disconnect tool from mains.
