The Tecfeed 250i suitcase wire feeder made by Technical Arc is robustly constructed in a reinforced moulded case to give a fully enclosed wire feed unit which is sealed against the elements.  By using a wire feeder, MIG welding is possible.  Designed to run off virtually any constant current or constant voltage power source, including MMA, MIG, TIG and engine driven welder generators.

Widely used by welders doing extensive hard facing, the Tecfeed is rugged enough to be used in even the harshest on site environments.  Technical Arc have even driven a small car over the case to check its durability.  The wire feeder requires no additional supplies, only welding cable connections and can run positive or negative polarity, giving outstanding performance with solid or flux cored wires.  This model is fitted with a heavy duty contactor with a good safety margin to allow welding up to 250A.


Burnback control, wire inching and 2T/4T controls are located inside the unit.
