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.

Key Features:

300 Amp primary output
Built-in current, voltage, power, time and pulse monitor
Primary short circuit protection
Triple pulse weld profile: W1, W2, W3, up to 19 pulsations per weld segment
I/O check screen
5-way cascade option using MA-650A
Pre-weld check process tool
RS232 or RS485 communications
Compact design
