Welding Procedure - Leister VARIMAT V2 Instructions D'utilisation

Device positioning
• Lift automatic hot-air welding machine applying pressure onto guide bar (27) and move to weld position
• Take welding plate (34) from holder and position according to Illustration E
WARNING: The welding plate (34) may only be removed from the holder and positioned if the welding
nozzle (9) has cooled down.
• Release the transport roller (16) by lifting it with the guide bar (27)
• Push the transport roller (16) to the left until it stops by applying light pressure to the shift spring (19)
• Swivel the guide roller (18) down
• The guide roller (18) should be set parallel to the edge of the pendulum roller (12) (see illustration F)
• Do a test run
• To correct the tracking, adjust the adjustment screw for tracking (13) (see illustration G and H, and the function
notes on the automatic hot-air welding machine)

Welding procedure

Perform a test welding according to the welding instructions of the material manufacturer and the
national standards or guidelines. Approve the test welding.
• Set welding parameters drive, heating and blower (chapter 1, Work mode)
• Welding temperature must be reached (heating up time approx. 3 - 5 min)
• Pull locking lever (11), lower hot-air blower (8) and move in welding nozzle (9) between the overlapping
sheets as far as the limit stop; drive motor starts automatically
No automatic start, see Drive sensor adjustment section
• Machine can be started manually with the controls (4) Drive
• The automatic hot-air welding machine is guided along the overlap at the guide bar (27). Guide the automatic
hot-air welding machines without pressure onto the guide bar (27) during welding. Pressure on the guide
bar (27) can lead to welding errors. Observe position of the guide roller (18)
• After the welding pull locking lever (11), move out hot-air blower (8) as far as the limit stop and swivel up
to the latching point
• After finishing the welding work, use e-Drive
In this way, the welding nozzle (9) is cooled down and the blower automatically switches off after approx.
4 minutes (section 1.8, Cooling down)
• Turn off main switch (3)
120
Disconnect power supply cord (1) form the line/mains.
