IS-1400CA Mid Frequency Inverter Weld Control

Formerly known as IS-1400CR

The IS-1400CA MFDC welder features closed-loop current, voltage, and power feedback, fast response times, and max output of 80kA making it ideal for small or large, single or mixed part manufacturing.

Built in the USA and packaged in a NEMA enclosure, the IS-1400CA comes 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.
