MIG030-120 is designed for AMICO ELECTRIC welding machines: MIG-160/180/200, MTS-165/185/205, MIG-140GS/200GS, MTS-200DP/250DP. Includes 100-pieces of 0.030-inch Tips, 10-pieces of Gas Diffusers, and 10-pieces of Gas Nozzles. Tip: The tip is made of high-quality #59 Copper, which is resistant to high temperature, corrosion, and has strong thermal and electrical conductivity. This ensures that the current is evenly transmitted throughout the wire at all times. The smooth center hole has low resistance, which reduces the friction during wire feeding, making wire feeding more stable. Diffuser: The diffuser is made of high-quality professional grade brass, which makes it extremely durable. The scientific production technology behind the diffuser makes welding easier and efficient. When replacing the wire reel, the tip does not have to be removed; the welding wire can be passed out directly. Nozzle: The nozzle is made of high-quality #59 Copper. It has excellent strength, provides good protection for the welding torch, and ensures that the protective air flow smooth. This creates a cleaner and more defined weld.
