Starting The Welding Process; Switching Off - Leister FUSION 1 Mode D'emploi

Overheating protection
If the drive is overheated due to external influences or if the melting temperature of the material in the screw is
too low,
the internal temperature protection will switch the drive off. Er 0400 will appear on the display (11). Disconnect
the FUSION 1 from the line supply and allow it to cool down.

5.3 Starting the welding process

If necessary, mount the appropriate welding shoe (8) (see Chapter 5.6, "Replacing the welding shoe").
• Once the operating temperature has been reached, welding can start. To do this, press the on/off drive switch
(15). Always operate the FUSION 1 with the welding rod inserted.
• Insert the welding rod (Chapter 5.1, "Welding rod") into one of the welding rod openings (2) and allow some
material to escape.
CAUTION: Never insert the welding rod into both welding rod openings at the same time.
• The welding rod must be clean and dry when it is inserted.
• The output can be changed on the basis of the rod geometry and choice of material using the output regula-
tion potentiometer (3). The set speed appears in a bar graph on the display (11).
• Pause the delivery of material using the on/off drive switch (15).
• Point the prewarming nozzle (17) at the area to be welded.
• Prewarm the area to be welded with oscillating movements.
• Place the FUSION 1 on the prepared area to be welded and press the on/off drive switch (15).
• Create and analyze a sample weld.
• Adjust the hot-air temperature as necessary using the air temperature potentiometer (10) and the output
volume as necessary using the output regulation potentiometer (3).
• The welding rod is automatically drawn through the welding rod opening (2) after starting.
It must be possible to insert the rod without resistance.

5.4 Switching off

• Press the on/off drive switch (15).
• Remove the welding material from the welding shoe so the welding shoe is not damaged the next time the
device is started.
• The FUSION 1 may now be stored on its side.
Use a fireproof support
The hot air flow must not be pointed at
people, animals, or objects
• Set the air temperature potentiometer (10) to "0". Allow the device to cool down.
• Switch off the hot-air blower switch (12).
