Most Common Causes

  • Loose work clamp, cable, torch, gun, or power connection
  • Worn contact tip, tungsten, liner, or front-end consumable
  • Wire feed or shielding gas inconsistency
  • Incorrect polarity, amperage, voltage, or process setup

Beginner Explanation

What this means in plain English

An unstable arc can feel like popping, surging, cutting out, or wandering. Check the electrical path, consumables, gas, and setup before replacing expensive parts.
