1. What is the primary problem of having excessive stickout? CORRECT ANSWER: Increased wire speed Explanation: Excessive stickout increases electrical resistance, which in turn leads to higher wire temperature and can cause the wire to feed faster than desired, potentially destabilizing the arc and reducing penetration. 2. What will happen when your voltage is set excessively low and your wire is set excessively high? CORRECT ANSWER: Spatter Explanation: Low voltage combined with high wi...
