TECNA Press-type
Spot Welders
Equipped with a built-in TE101 Dual Schedule Microprocessor Type Welding Control with Dual current, dual weld time, upslope and pulsation, TECNA press spot welders are robust and versatile. Constructed with a rugged welded steel frame, the stationary, single phase unit designed by TECNA is air operated and water cooled, available in dual voltage 220v/480v.
Features of TECNA Press Spot Welders
