Calibration unit MCU 1000

Calibration unit MCU 1000

For the calibration of welding units according to DIN EN 1090, IEC 60974, EN 50504, DVS 3009. The periodical calibration of welding units is a requirement to guarantee reproducible welding results and a production according to certificated welding specifications (WPS).

Applicable for MIG/MAG, TIG, MMA and Plasma welding!

The calibration unit is universal applicable for the calibration of all standard arc welding units from any brand. The welding unit is connected to the automatic step-switched load resistor (max. 1000 A). With an external sensor unit the wire feed speed and the gas flow of MIG/MAG units can be monitored. An analysis and documentation software is supplied with the calibration unit. It allows a comfortable documentation of the measurement. A pc or notebook is required and not included. Because of the compact dimensions and the weight the unit is ideally suited for mobile use in service.

Calibration unit composed of:

1.Load resistor 1000 A
2.External sensor for wire feed speed and gas flow


-Display for a comfortable adjustment and illustration of parameters and measured data.
-Solid Aluminum case for a mobile use in service.


-High duty cycle due to active cooling of the load resistor with fans.
-Automatically controlled step-switch.
-HF safe design for the calibration of TIG units.
-External control via pc software.
-Measurement of welding current and welding voltage (+/- 1.0 % accuracy) .
-Measurement of environmental parameters (temperature, supply voltage 1phase/3phase) .
-Automatic over-heat switch-off.
-Connection for the external sensor for measurement of wire feed speed and gas flow.

Range of measurement:

-Welding current (0-1000 A)
-Welding voltage (0-100V)
-Wire feed speed (0-30 m/min)
-Gas flow (0-20 l/min)
-Supply voltage
-Temperature (0-50°C)
