Before beginning model preparation
tasks it is necessary to clean the surfaces
of parts to be welded thoroughly by
sanding or using a rubber.
The use of flux in liquid or paste form is
recommended.
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.
