M-500 Single Torch External Welding System

Lightweight, ambidextrous system with advanced auto control features


The CRC Evans M-500 single torch external welding system is rugged, lightweight and capable of a range of applications outside traditional pipeline welding.

The M-500 delivers exceptional arc visibility, high-speed travel, and intuitive single-action installation. The onboard voltage and current sensing and adjustable head allows rapid angle changes for consistent weld quality and high production rates. Wire can be onboard or offboard

Built-in data logging collects critical welding data at specified intervals including tilt angle, torch oscillation bpm and width, tracking parameters (volts, amps, impedance), heat in joules per unit distance, travel speed and travel accumulated distance. An assumed rate of 25,000 samples per second accommodates short-term variations in individual voltage and current readings.

The M-500’s single action driver and latching system allows seamless installation to the band. The high-speed travel motor automatically returns the system to a user-defined position after finishing a pass, helping to reduce manual re-latching error. The fully automated tilt sensor calibration further increases efficiency
