Typically, your welding machine should be maintained and calibrated every 12 months for standard grade equipment and every 6 months for precision grade equipment. Welding machine compliance testing” refers to the process of periodically inspecting and testing a welding machine to ensure it meets safety and performance standards, usually including electrical safety checks, current and voltage accuracy verification, and functionality assessments, all conducted according to relevant industry regulations and standards like IEC 60974-4, typically done annually or based on usage conditions and manufacturer recommendations. 

• What is tested:

  • Electrical safety: Insulation resistance, earth continuity, leakage current 
  • Welding parameters: Voltage, current, wire feed speed accuracy 
  • Functionality checks: Proper operation of switches, controls, alarms 
  • Visual inspection: Checking for damage, wear, loose connections
