Operational condition
• Check the nozzle’s basic setting. (Detail A)
• Automatic drive
Automatic drive is adjusted as required, depending on nozzle position by means
of switch pin (26) and set screw (27).

According to the application, the guide roller (25) is set to "active" (operational) or
"deactive" (non-operational) by means of guide roller knob (24) and guide roller
lever (23) (see Details B and C). The guide roller (25) causes the automatic welding
machine to carry out a straight run to the edge of the welding seam.

In case the maximum temperature is not reached, reduce air volume by means of
manuel air vane (14) and potentiometer for air flow (20).
Tool positioning
• Swivel hot air blower (3) using swivel lever (22) up to the stop.
• Operate lifting device (11) by means of lifting device lever (16) so that
drive/pressure roller (6) and drive roller (9) are at no-load.
• If welding is being carried out by means of guide roller (25), lock guide roller lever
(23) into support bracket (12) (see Detail B).
• Position automatic welding machine into the overlap of the material to be welded.
The outside edge of drive/pressure roller (6) and guide roller (25) must line up with
the overlap edge of the material to be welded.
