Verify via Official Channels
Purchase through the brand's official website or authorized dealers, request a valid purchase invoice, and cross-check the machine's serial number against the brand's official database to avoid refurbished units with tampered serial numbers.
Inspect Machine Markings
Genuine equipment features clearly printed, standardized nameplate specifications and intact 3C certification marks; the build quality is precise, free of burrs or signs of tampering on screws. Counterfeits often exhibit exaggerated specifications and blurry markings.
Verify Performance and After-Sales Support
Genuine units qualify for free inspections at official service centers and come with full warranty coverage. Counterfeits lack official after-sales support, and test welds reveal arc stability and weld bead formation that fall far short of genuine standards.
Check Accessories and Craftsmanship
Standard accessories-such as the welding torch, tungsten electrode, and gas hose-bear the brand's exclusive logo and exhibit high-quality workmanship. Counterfeits typically use cheap, generic parts with poor gas-tightness, leading to issues like gas leaks and ineffective shielding.
