9. TWECO MIG TORCH (Cat No: 10-6105 where supplied)
9.1 Introduction
The Tweco MIG Torch and cable has the potential to be the greatest source of problems for the
Vikings. The TWECO 250A gun fitted to the Viking offers robust construction, unparalleled
reliability and easy replacement of consumable parts. The TWECO 250A has an operating
capacity in excess of the capacity of the Vikings and can be expected to give trouble free service.
TWECO MIG Torches may be fitted to many different types of MIG welding Power Supplies so
that your whole shop can be converted to TWECO. Not only will this give greater reliability (and
hence greater productivity), but it will reduce stockholdings of consumable parts. See your
THERMAL DYNAMICS distributor for details.
