Voltage Calibration
Voltage is a critical welding parameter and an essential variable across all major national and international standards. Even small shifts in voltage can alter weld properties and introduce unacceptable discontinuities. Accurate voltage indication on the welding machine is therefore fundamental to producing consistent, compliant, high‑quality welds.
Current Calibration
Welding current is also an essential variable referenced in every recognised welding standard. Variations in current directly influence weld penetration, bead shape, and overall joint integrity. Ensuring the machine displays true current output is vital for maintaining repeatable, code‑compliant weld quality.
Gas Flow Calibration
Shielding gas flow rate is another essential variable controlled by welding standards. Incorrect gas flow can lead to porosity, oxidation, and other weld defects. Verifying that the machine delivers and displays the correct gas flow rate is essential to achieving stable arc performance and producing sound welds.
