Changing the contact tip when welding is important for several key reasons, especially in MIG/MAG (GMAW) welding where the tip wears out over time. Here’s why it matters: 1. Consistent Wire Feed and Arc Stability A worn tip has an enlarged bore, allowing the wire to wander or make poor contact. This causes an unstable arc, spatter, and inconsistent weld quality. A fresh tip keeps the wire centered and the electrical contact consistent. 2. Proper Current Transfer The contact tip is where welding
