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

The IS-300CR 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.

The unit features flexible weld profiles allowing for three pulses in each weld cycle. Each weld segment may be programmed with upslope and down-slope and up to 19 pulsations. You can also change the control mode for each weld segment.

IS-300CR is a great choice for small and medium scale applications where closed-loop feedback control and fast response times are required like wire termination, switch assemblies, battery tabs, foils, and tang welds.

IS-300CR may be used in conjunction with one of our many weld heads as a single operator benchtop unit and is 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.
