What tool is used to clean a dirty torch tip orifice?

The tool specifically designed for cleaning a dirty torch tip orifice is broaching wire. This tool is typically a thin, flexible wire that can be fed through the orifice of the torch tip to remove any accumulated slag, spatter, or other debris that may impede the proper function of the torch.

Using broaching wire is particularly effective because it can reach the narrow openings and remove blockages without damaging the tip itself. This is crucial as maintaining a clean orifice ensures a stable and precise gas flow, which is essential for achieving optimal welding performance.

While wire cleaners and chemical cleaners can assist in cleaning various welding tools and equipment, they are not tailored specifically for the unique requirements of torch tip orifice cleaning. A reamer, on the other hand, is generally used for larger diameter openings and might not provide the precision needed in this situation.
