Fixing Arc Instability from Gas Flow Issues

Arc instability from gas flow issues occurs when flow rates are too high (causing turbulence) or too low (allowing atmospheric contamination). Solution requires optimizing flow rate for the specific application and environmental conditions.

Flow Rate Optimization

  1. Start with baseline flow. Use 12-15 L/min for most MIG applications as starting point.
  2. Adjust for conditions. Increase flow for drafty conditions, decrease if causing turbulence.
  3. Check for leaks. Ensure gas delivery system has no leaks affecting pressure and flow.
  4. Monitor arc behavior. Stable flow produces consistent arc sound and appearance.
