Welding anti-spatter: real advantages for production

In MIG/MAG processes, spatter is inevitable. The problem is not the spatter itself but the adhesion: when it welds onto the part, it requires subsequent grinding, and when it builds up in the torch nozzle, it impairs the shielding-gas flow and generates porosity in the bead.

Anti-spatter creates a barrier between the spatter and the surface. Applied to the part, it allows the spatter to be removed with a brush or spatula, without grinding. Applied to the nozzle and contact tip, it drastically reduces buildup and the frequency of cleaning or replacing these consumables.

The gain is measured in cell time: fewer stops to clean the torch, fewer minutes of finishing per part and fewer consumables replaced per shift. On lines with high welding volume, the return on investment is immediate.

JEFLUB's ARS Lub is an easy-to-apply anti-spatter that protects parts, fixtures and torch consumables. Request a demonstration on your welding line.
