IS Series

Mid-Frequency Inverter Weld Controls

The IS Series - Mid-Frequency Inverter Weld Controls feature closed-loop current, voltage, and power feedback, fast response times, and a wide range of output power - 0.050-80 kA in 4 ranges. This makes them ideal for small or large, single or mixed part manufacturing.

Six different weld control models allow the user to select the best mode for the application: primary limit, primary and secondary RMS, power RMS, voltage conrole or pulse percent.

Packaged in a NEMA enclosure, the new units come as standard with a rotary handle and internal circuit breaker. It has a â€œtriple pulseâ€ weld capability which provides flexible weld profiles and enables three pulses in each cycle. Each weld segment can be programmed with upslope and downslope and may contain up to 19 pulses.

Key Features:

800 A or 1400 A primary output
Six feedback modes
Built-in current, voltage, power, time and pulse monitor
Optional displacement monitoring and proportional regulator control
Primary short-circuit protection

Triple-pulse weld profile: W1, W2, W3, up to 19 pulsations per weld segment
Pre-weld check process tool
I/O check screen
Cascade option: 5 and 7-way cascade
RS232 or RS485 communications
NEMA style enclosures
