FAQ - WeldAid
FAQ FREQUENTLY ASKED QUESTIONS Solving a variety of typical problems with MIG/Wire Welding. Grinding the spatter is an effective traditional solution, but is expensive, time consuming, and fatiguing. The easiest, most-effective solution is the use of anti-spatters. There are two types: Solvent-based and water-based. Solvent-based are the easiest to use, though water-based are more effective
Conversely, if the liner is too small, the wire won’t feed properly, also leading to wire feeding problems. Lastly, depending on the welding process and the wire, a different shielding gas may be needed to avoid poor weld quality and/or defects that require rework.
