For the first time in the history of Fronius
we have especially gone into the Demands for the uses
of the gas –watercooled applications, in the development
of the Welding Torches.
…to get the very most out of both Variations.
(The Wear Parts and the Welding Torches are optimally matched to the Welding Power.)
…to get the best possible standing time for the Wear Parts and the
Welding torches.

Why spiky contatct tips?
17
/Low absorption of radiant heat
by new top-contact tip geometry
/Up to 70 °lower temperature
on the wear parts
/Therefore longer lifetime
