Operation

Tool positioning

• Swivel hot air blower (3), using swivel lever (19) up to the stop.
• Operate lifting device (26) by means of lifting device lever (13) so that welding rod pressure roller (6) and
drive roller (7) are at no-load.
• Position automatic welding machine over the joint to be welded.
• Insert welding rod through welding rod guide tube (20) and pull under the welding rod pressure roller (6)
and place it in the joint.
• The guide roller (21) must run in the welding joint.
• Activate lifting device (26) by means of lifting device lever (13) so that the automatic welding machine is ready
to start.

Welding parameters

• Set potentiometer for welding speed (16) to required value.
• Set potentiometer for air flow (17) to required value.
• Set potentiometer for air temperature (18) to required value.
• The pressure derives from the actual weight of the automatic hot air welding machine.

Welding procedure

• Swivel hot air blower (3) up to the stop using swivel lever (19). The welding process starts automatically via
automatic drive.
• If necessary, the tool can be started manually by means of the drive switch (15).
• Check the welding process:
• Wall switch-off (9)
When contact with the wall, is made drive and heater are switched off automatically.
• After finishing welding swing up the hot air blower (3) to the stop using swivel lever (19). The welding process
stops automatically.
• After completing welding work, set potentiometer for air temperature (18) to zero so that hot air blower (3)
cools down.
• Switch off the tool at the main switch (14).
• Disconnect the tool from the mains.
