EDM Zap designs and manufactures its own line of EDM power supplies — single and multi axis CNC and custom configurations — engineered for stability, precision, and decades of reliable production.
Over five decades of EDM expertise
Equipment serviced worldwide
Custom Engineered Solutions
Most EDM power supplies on the market are built to a price point. EDM Zap builds them to a performance standard. Our Advantage series CNC and ZNC power supplies are designed, manufactured, and tested at our facility in Montgomery, IL — giving us full control over quality, reliability, and customization.
Every unit is engineered for the demanding realities of production EDM — stable discharge output, minimal electrode wear, and consistent surface finish across long production runs. Whether you’re running 24/7 aerospace components or precision medical parts, the power supply is the heart of your process.
Because we manufacture our own equipment, we also support it better than anyone else. Our technicians understand every circuit, every board, every parameter — which means faster diagnosis, better repairs, and a longer machine life for your investment.
Product Range
Full multi axis CNC-controlled power supply with programmable parameters, automatic arc detection, and digital output monitoring. Designed for high-volume, repeatable production environments.
Manual single axis power supply for sinker EDM operations. Simple, reliable, and built for shops that need straightforward performance without complex programming overhead.
Specialist power supply configurations engineered for nuclear and energy sector applications — built to tighter tolerances with additional documentation and traceability requirements.
Need something the shelf doesn’t offer? We engineer power supplies around your specific machine tool or fixture setup. Custom builds ship fully tested and documented.

"EDM Zap delivered a custom solution that reduced our downtime by 40%. The engineering support was exceptional from day one."
"We've relied on EDM Zap for 20 years. Their calibration team is second to none. When they say precision, they mean it."
What's Included
Consistent voltage and current delivery across the full duty cycle — no output drift, no arc instability, no surprises mid-run.
Built-in arc detection circuitry automatically adjusts power parameters to prevent DC arcing and protect both the electrode and workpiece.
Proprietary discharge waveform technology minimizes electrode consumption — extending tool life and reducing consumable costs across long production runs.
Real-time display of voltage, current, pulse frequency, and duty cycle parameters — giving operators full visibility into machine performance at a glance.
Every unit is designed to be serviced by EDM Zap technicians. Board repairs, component replacement, and recalibration — all handled at our Montgomery, IL facility.
Non-standard machine tool arrangement or non-standard fixture setup? We modify or build from scratch to match your exact requirements.
