IS-300A - Inverter Spot Welder
Mid-Frequency Inverter Resistance Welding Control
The IS-300A - Inverter Spot Welder is small enough to fit on a bench, which is ideal for customers and integrators who require high output, but have limited production space.

The IS-300A - Inverter Spot Welder offers a range of new and improved features including six control modes (primary limit, primary and secondary root mean square (RMS), secondary constant power, secondary voltage control, and fixed pulse) and 0.050 kA - 20 kA of power in 3 ranges. The low current ranges are ideal for small or fine applications.
