M-500 Single Torch External Welding System

Lightweight, ambidextrous system with advanced auto control features


CRC Evans’ (CRCE) M-500 Single Torch External Welding System delivers exceptional arc visibility, high-speed travel, and intuitive single-action installation. Onboard voltage and current sensing and adjustable head allows rapid head angle changes. The M-500 provides reliable and consistent weld quality enabling high production rates and helping to reduce operational time and cost.

The auto head angle and head travel angle (leading or lagging) changes with the welding parameter’s screen. This enables a position setting for tip changes and maintenance. Based on tilt, the head travel angle can be automatically changed during welding. Ambidextrous design allows the operator to reverse travel direction, tilt readings and head angle via a single clockwise or counterclockwise parameter.

Built-in data logging takes snapshots of critical welding data at specified interval storing key data 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 driver and latching system allows seamless, single action installation to the band. A high-speed travel motor automatically returns it to a user-defined “home” position after finishing a pass. This eliminates manual re-latching errors and the need for fully automated tilt sensor calibration which further increases efficiency.
