They are exposed to heat, weld spatter and radiation and have to go to their limit every day: consumables of MIG/MAG welding torches. The gas nozzle, contact tip, gas diffusor and contact tip holder are very close to the process during welding and must reliably perform their respective tasks. The demand on material, processing and process reliability for these wear parts are extremely high.Gas nozzles, contact tips & co. are mass-produced goods, so the offer on the market is correspondingly versatile. For many users who buy consumables for their welding torches, the price is decisive. If the quality of the weld seam does not meet the expectations or the welding torch does not work as desired, this may be due to the cheap quality of the wear parts. There are great differences not only in the material used, but also in the processing that influence the welding result. It makes sense to buy gas nozzles, contact tips, gas diffusors and contact tip holders from a quality supplier. Ideally from the respective welding torch manufacturer, because original torches and original wear parts are a perfect match and ensure the best performance.
