MAINTENANCE AND USE MANUAL
the following illustrations show an example of how to bind together two pieces to be welded directly
on the master model.
Fig. 19: adjust the spot-welding power by rotating the
dial (A) on the frontal display of the Quasar.
Fig. 20: Position the elements (X) to be welded on the
model (Y).
Connect the earth by attaching the clip (E) to one of
the elements (X).
Before beginning model preparation
tasks it is necessary to clean the surfaces
of parts to be welded thoroughly by
sanding or using a rubber.
Fig. 21: Grip the handpiece (B) and rest the electrode (C)
on the zones to be joined together; pressing the pedal (D)
generates a discharge lasting a few tenths of a second.
the tip melts and produces a metal point that joins and
locks together the two parts to be welded.
Three points will generally be enough to lock the two parts to be welded
together. The presence of ARGON (F-G-H) eliminates the risk of oxidation.
Fig. 22: Fix also the solder with one or two points, then
apply a little flux of a type appropriate for the alloy used.
The use of flux in liquid or paste form is
recommended.
