HG3000 AC and DC welding machine field calibrator


The HG-3000 AC and DC welding machine field calibrator (hereinafter referred to as the calibrator) is a calibration equipment designed for the current and voltage meters on various electric welding machines. Because the voltage or ammeter meter of the welding machine is difficult to disassemble and assemble, and the current and voltage accuracy of the welding machine directly affect the welding quality of the welding machine, the calibration of the voltage and ammeter is very important.

  • Product description
  • I. Overview
    The HG-3000 AC and DC welding machine field calibrator (hereinafter referred to as the calibrator) is a calibration equipment designed for the current and voltage meters on various electric welding machines. Because the voltage or ammeter meter of the welding machine is difficult to disassemble and assemble, and the current and voltage accuracy of the welding machine directly affect the welding quality of the welding machine, the calibration of the voltage and ammeter is very important. This calibrator designed by our company for electric welding machines is very convenient and safe to use. There is no need to disassemble and assemble the electric welding machine. It can be inspected directly on site. The accuracy and stability are very high. It is an ideal calibration equipment for electric welding machines.

    2. Technical characteristics
    2.1 This calibrator is a six-and-a-half-digit display, highly stable, safe and reliable on-site measurement instrument. It adopts LCD color LCD digital display and can display AC and DC current, voltage, gear, output value, etc. on the same screen.
    2.2 This calibrator uses advanced circuits and high-precision integrated circuit chips dedicated to instrumentation to ensure the measurement accuracy and reliability of the calibrator.
    2.3 The measuring range of this calibrator is wide. Especially when large current is input, the instrument will generate heat, so the material selection is very important. Our company uses samplers imported from abroad. When the current is large, the thermal stability of this instrument is very good. .
    2.4 This calibrator adopts a variety of software and hardware anti-interference measures and digital compensation technology to ensure that the instrument is not affected by harsh environments when used on site.
    2.5 This calibrator can perform online on-site calibration of voltmeters or ammeters on welding machines below level 0.2. It is lightweight and easy to carry.

    4. How to use
    4.1 Preheat the instrument for 10 minutes before using it, and turn on the power of the welding machine while preheating.
    4.2 After preheating, connect the positive and negative output lines of the welding machine to the positive and negative input lines of the on-site calibrator.
    4.3 Slowly adjust the output potentiometer of the welding machine clockwise so that the output current or voltage of the welding machine goes from zero to the maximum value. During the adjustment process, digitally compare the current or voltage indication on the calibrator with the meter indication on the welding machine. Yes, based on the difference, check whether the accuracy of the welding machine is within the specified error range.
    4.4 The welding machine can be calibrated and repaired based on the measurement results to avoid affecting the welding quality of the welding machine.
