Formerly known as IS-300CR. Small enough to fit on a bench, the IS-300CA 300 amp MFDC welder is ideal for customers and integrators who require high output, but have limited production space.

The IS-300CA 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 .050-20 kA of power in 3 ranges. The low current ranges are ideal for small or fine applications.

  • 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
