The IS series mid-frequency inverter resistance weld controls feature closed-loop current, voltage, and power feedback, fast response times, and a wide range of output power – 0.050-160 kA in 4 ranges – making them ideal for small or large, single or mixed part manufacturing.

Packaged in a NEMA enclosure, the new units come standard with a rotary handle and internal circuit breaker. It has a “triple pulse” weld capability which provides flexible weld profiles allowing for three pulses in each cycle. Each weld segment can be programmed with upslope and downslope and may contain up to 19 pulses.

Users can also change the control mode for each weld segment. The fully-featured model boasts advanced force and displacement features unique to the unit including initial part thickness check, weld to displacement, and the ability to set final displacement limits.

Three models are available: IS-800CR with a max output of 40 kA, IS-1400CR with a max output of 80 kA and IS-2200CR with a max output of 160 kA.

IS Series inverters are well-suited for integration into semi or fully automated resistance welding systems.  AMADA MIYACHI specializes in designing and building fully integrated, semi-automated and fully automated resistance spot welding machines.  See our Integrated Systems brochure for more information.
