III. Genuine Parts Procurement & Technical Support
During the use of water-cooled welding torches, consumables such as contact tips, nozzles, O-rings, and wire liners are easily worn out. Regularly replacing them with genuine original consumables can significantly reduce wire feeding resistance, prevent water and gas leaks, and improve welding quality. We guarantee to provide 100% genuine original parts and keep ample stock.
