Globular Transfer Troubleshooting: Avoiding Unstable Transfer
Globular transfer occurs when voltage is too high for short-circuit mode but current is below spray transfer threshold, creating large irregular droplets with excessive spatter. Avoid this unstable transfer mode by adjusting parameters to achieve either stable short-circuit or spray transfer characteristics.
Globular Transfer Correction
- Parameter Adjustment. Either reduce voltage for short-circuit mode or increase current above spray threshold (typically 180A+ for 1.2mm wire).
- Gas Selection Impact. High CO2 content gases promote globular transfer. Use CORGON® S5 or reduce CO2 percentage for better control.
- Wire Speed Optimization. Adjust wire feed speed to match desired transfer mode - don't operate in the globular transition zone.
CORGON® S8
Spray Transfer OptimizedWhy CORGON® S8 eliminates globular transfer: The optimized 8% CO₂ content lowers the spray transfer threshold current, enabling smooth spray transfer at lower amperages where globular transfer would otherwise occur with higher CO₂ mixes. Certified to ISO 14175 (M20-ArC-8) for consistent composition control [ISO 14175:2008].
Setup for stable transfer: Use CORGON® S8 at 15-18 L/min, adjust wire feed speed above spray threshold (typically 160A+ vs 180A+ with 18% CO₂). The lower CO₂ content provides a wider stable spray transfer operating window.
