TungStuds Performance
The TungStuds are welded on in a grid pattern
The space between the TungStuds become embedded
with mineral debris (Rock-Box-Effect)
Extensive wear protection

Welding Process
TungStuds are quickly welded on
Can also be used on uneven surfaces
When TungStuds are worn, simply replace them
Individual TungStuds can also be replaced
Resistant to wear thanks to tungsten carbide core
Less maintenance work means higher productivity
Cost reduction through less downtime
Minimal spare parts expenditure

Ceramic Ferrule
The ceramic ferrule concentrates the arc
Eliminates the air in the welding area through a metal-
fume-atmosphere
Shaping of the welding bead

Contact Pin
Tungsten Carbide
Steel Body
Aluminium Contact Pin
Aluminium is needed to ignite the welding process
Aluminium stills the melting pool
Aluminium binds nitrogen and eliminates pores
