Aluminum tig welding

We have V310 T technologically advanced AC/DC Miller dynasty series 700 tig welding machine that is used to weld aluminum outdrive on boats.
The flat rates to tig welding aluminum boat lower units is $90.00.

Trish can do 400 / 800 / Cobra upper gearcase tig welding do to frozen water or we have new units for years 1977 to 1993.

Outdrives with broken skeg or lower unit aluminum top fin in most cases the sterndrive can be left together.
With our new high frequency arc, square wave, fast freezing puddle and deep penetration there is a lower amount of heat generated.
