Fixing MIG Spatter from Voltage Issues

Excessive MIG spatter from voltage issues occurs when arc voltage is too low (stubbing, short-circuit) or too high (irregular transfer). The solution requires finding the optimal voltage window for your wire feed speed and gas combination.

Voltage Optimization Steps

  1. Start with manufacturer recommendations. Use voltage charts for your wire diameter and gas type as baseline.
  2. Adjust for transfer mode. Spray transfer requires higher voltage than short-circuit for same wire feed speed.
  3. Fine-tune in 0.5V increments. Small adjustments have significant impact on spatter levels.
  4. Match to wire feed speed. Voltage must increase proportionally with wire feed speed increases.

CORGON® 18

Low Spatter

Why CORGON 18 reduces spatter: The optimized 18% CO2 content provides smoother arc characteristics and wider voltage windows compared to pure CO2, reducing spatter across parameter ranges.
