Arc Welding Transformer


Arc Welding Transformer

Powercon offers FMT series of forced air-cooled manual arc welding transformers. These are specially designed to meet today’s demand at sites and workshops as well. The optimally designed taper moving core system ensures superior dynamic characteristics resulting in a smooth and soft arc with minimum spatter. Compact, sturdy and really portable these sets are manufactured with Class ‘H’ insulation for long trouble-free service life. These are extremely operator-friendly, and more so since both the current scale and the current control handle are located on the front panel. Due to the two large wheels at the rear, castor/stay at the front, the transformer can be steered to any position effortlessly. The company offers Arc Welding Transformer, Thyristorised Welding Rectifiers, Arc Welding Transformer, Arc Welding Transformer, etc.
