How Can I Clean the Spatter Disc/Gas Diffuser?

As on a gas nozzle, the buildup of spatter on the gas diffuser/spatter disc will also inhibit the flow of gas. The gas diffuser/spatter disc is held into the front of the torch by the by the support tube which is held in place by the collet nut (if you are using a slip-in tip) or by the threaded contact tip. This gas diffuser/spatter disc disperses the shielding gas required for MIG or gas-shielded flux-cored welding. On a regular basis, remove the gas cup, tip (collet), and support tube and check the diffuser to ensure that it’s not clogged. If there is spatter in the diffuser, use a razor blade to clean, a small wire to clean holes or a rag to just wipe it clean.
