Excessive Spatter (Contamination/Magnetism)

Contaminated/Magnetically Charged System

Fronius · TPS i Welding Machine

What does Excessive Spatter (Contamination/Magnetism) mean?

Excessive welding spatter is occurring, which may be caused by contamination or magnetic charging of the shielding gas, wirefeeder, welding torch, or workpiece. These conditions can destabilize the arc and droplet transfer.

Common Causes

  • Shielding gas is contaminated.
  • Wirefeeder is contaminated.
  • Welding torch or workpiece is contaminated or magnetically charged.

Repair Steps & Checklist

  1. 1

    Perform an R/L alignment (resistance/inductance) to optimize the welding circuit.

  2. 2

    Adjust the arc length parameter for better arc stability.

  3. 3

    Inspect the shielding gas supply, wirefeed path, welding torch position, and workpiece for any contamination or magnetic charging.
