Resistance Spot Welding Power Supplies

Mid-Frequency Inverter Resistance Welding Power Supplies - ISA Series

The ISA range of inverter resistance welding power supplies provides the highest level of control available today in what we call 'large scale' resistance spot welding. All models are intelligently packaged in NEMA-style enclosures and are designed to deliver robust performance in even the harshest of production environments. The ISA models can deliver 500, 1000, 2000 and 4000 amps of primary welding current, respectively.
