The Nozzle Cleaning and Spray Unit effectively removes burrs that form during the welding process, eliminating residues that accumulate on the nozzle and nozzle holder in the welding zone. This improves the flow of gas leaving the nozzle and prevents potential welding defects during the welding process. With the addition of the spray unit, the amount of spatter on the nozzle, flow nozzle and nozzle holder is reduced, resulting in more efficient and cleaner welds.
