8. Pull the trigger to create an arc. The creation of an arc means that the device started conveying
wire.
9. If the weld nugget is large enough, slowly move the burner along the path you wish to weld.
10. The burner emitting an unusually loud buzzing noise and a tear forming at its tip indicate that
the wire feed speed setting is too low and should be increased. Irregular sounds and spatter on
the other hand indicate that the wire feed speed setting is too high. When operating with an
ideal wire feed speed, a steady noise should be heard. A porous welding seam indicates a lack
of gas supply.
11. Check the name plate for information concerning the duty cycle of the device. The percentage
values describe the period of use within a cycle of 10 min. 60 % for example indicates a period
of use of 6 min and a rest period of 4 min. In case of the welder being overloaded, the device
will automatically stop operating to prevent its components from being damaged. In case the
device should automatically shut down, give it enough time to cool down. Leaving it turned on
during the cooling period will allow the internal fan to speed the process up.
Maintenance
Caution:
Only qualified technical personnel may perform repair and in-depth maintenance work on this
