Why anti-spatter paste Düsofix?
With gas-shielded metal arc welding, weld spatter inevitably occurs. This can result when igniting the arc, in the event of short circuits or even when metal droplets from the wire do not hit the weld pool or splash out of the weld pool again. These can spread in all directions. Welding particles not only get on the workpiece and the clamping elements – if they are in use – but also on the front end of the torch itself. Gas nozzle, contact tip and gas diffusor are wear parts that are closest to the process and are therefore directly exposed to the hot particles.

Residues on gas nozzle & co.
A gas nozzle already has a very smooth surface, but this alone does not prevent weld spatter from burning into the gas nozzle and the other wear parts inside it and disrupting the gas flow. An anti-spatter agent especially for gas nozzles & co. largely counteracts the sticking of weld spatter. Without the use of an anti-spatter agent, weld spatter sticks and disrupts the laminar shielding gas flow. As a result, the arc is not adequately protected from ambient air due to insufficient gas flow, which can lead to pore inclusions. This means reworking the weld seam or even scrap if reworking is not possible.

If welding particles settle directly on the front of the contact tip and thus build up a spatter bridge to the inside of the gas nozzle, this can lead to an undesirable current transfer from the gas nozzle to the workpiece. Splashes at the tip of the gas nozzle can also significantly disrupt a smooth wire feed. Depending on the extent of the malfunction, this can even lead to so-called wire sticking. In this case, the only solution is interrupting the welding process and replacing the contact tip.

Ideal for the welder’s tough daily routine
The anti-spatter paste Düsofix is filled into a metal can and has a very good stand thanks to its practical shape. It is also securely positioned in tough working conditions and where the work materials are not handled with care. Dents do not affect the can and have no influence on the anti-spatter agent itself.
