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: – Guide roller (21) must run in the joint.
– The welding bead must be visible. Adjust welding
parameters using the potentiometers (16), (17)
and (18) if necessary.
• Wall switch-off (9)
When contact with the wall, is made drive and heater are switched off automati-
cally.
• 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.
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 auto-
matic 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.
