AMI Model 207 / 207A Orbital Welding Power Supply
Model 207 / 207A
For twenty-five years the 207 was the system of choice for the biggest mechanical contractors in the country. Thumbwheel-simple next to today’s touchscreens, and still welding tube in plants that were built before half the crew was born.

On our bench
What we see fail on a 207: main board and pot faults, contactors, thumbwheel and switch wear, high-frequency start problems, gas solenoids, coolant leaks, and cables that have been walked on for thirty years. Almost all of it is repairable, and every one of them can be brought back into calibration.

Repair, rebuild, parts and on-site calibration — anywhere in North America.
