Micro Arc Welding Checkers & Monitors

Reliable Micro Arc Welding requires process monitoring and checking at the highest level. MacGregor Welding Systems offers different welding monitoring and testing devices that enable the user to control monitoring criteria, such as welding current, welding voltage, electrode penetration and electrode force.


Digital Welding Force Gauge

The WFG series digital force gauge is a state-of-the-art technology in electrode force measurement. Designed specifically for opposed and parallel gap weld head force measurement, these units combine robust ergonomic design with electronic precision, offering single-handed operation in a durable and easy-to-use unit.


  • External trigger input to capture electrode force at the moment a weld is triggered.
  • Audible indication of errors, including overload, high and low force conditions.
  • Automatic and manual tare functions.
  • Automatic power off - PP3 battery operation.
  • User selectable measurement units.
  • Data HOLD feature.
  • RS-232 data port for data capture and calibration.
  • Operator mode, using set point and upper & lower percentage limits for force validation.
