Operation
Operating condition
• Before putting into operation, check power supply cord (2) and connector as well as extension cable for electrical
and mechanical damage.
• Check the nozzle setting:
the nozzle must maintain a distance from the base material and the welding rod of about 2-3 mm.
• When welding linoleum, lower the cover on to the welding nozzle (4) (see Detail A: page 16).
Connect tool to rated voltage.

FI
400 Rated voltage stated on the device must correspond to line/mains voltage.
Extract hot-air blower in case of power breakdown.
Operating Instructions
• Perform a test welding according to the welding instructions of the material manufacturer and the national
standards or guidelines. Check the test welding. Adapt the welding temperature (welding parameters) as
required.
Tool positioning
• Swivel hot air blower (3) up to the stop using swivel lever (19).
• Position the automatic welding machine over the joint to be welded.
• Insert the welding rod through the welding rod guide tube (19), pull it under the welding rod pressure
roller (6) and place it in the joint.
• The Guide roller (20) must run in the welding joint.
Welding parameters
• Set potentiometer for welding speed (14) to the required value.
• Set potentiometer for air temperature (16) to the required value.
• Turn on the air blower switch (15), set the two stage switch for airflow (17) at setting 3 and heat up for
about 5 minutes.
• Important: low voltage.
If the maximum temperature is not reached, reduce the airflow by means of the manual air valve (11) and the
two stage switch for air flow (17).
• The contact pressure is effected through the weight of the automatic hot air welding machine itself.
Welding procedure
• Swivel hot air blower (3) up to the stop using swivel lever (18) and at the same time turn on the drive
switch (13) (The welding process starts).
• Supervise the welding process:
– Guide roller (20) must run in the joint.
– The welding bead must be visible. If necessary adjust the welding parameters using the potentiometer (14).
• Wall switch-off (9)
When contact is made with the wall, the drive and heater are switched off automatically.
• When welding is finished, swing up the hot air blower (3) to the stop by means of swivel lever (18).
• Switch off the drive switch (13). Cut off the welding rod. Re-position the automatic welding machine as
necessary.
• After completing work, set potentiometer for air temperature (16) to zero so that hot air blower (3) cools
down. Then turn off the air blower switch (15).
