Heavy Duty Projection Welders

Designed to produce high welding forces without deflection, T. J. Snow’s heavy duty press- type resistance welders are available in a variety of set-ups including (but not limited to)— Spot (with arms), Projection (with platens) and Combination Spot and Projection (arms & platens). Standard AC transformer sizes range from 50-500 KVA, with larger capacities and custom options available. MFDC and Three Phase Frequency Converter power supplies are also available.
