Selection & Setup Notes

500 A is a heavy-duty source. Always run it with a water-cooled torch and the MSW-20L chiller, plus the DJC-01 torch guard to protect the torch body.

Standards & Further Reading

External reference: ISO 9013 — Thermal cutting classification — ISO 9013 defines the quality classes for thermal cut surfaces (perpendicularity, bevel, dross).

Frequently Asked Questions

Is water cooling mandatory at 500 A?

Yes. At this current an air-cooled neck overheats within minutes; water cooling is a prerequisite for continuous operation.
