Cougartron weld cleaners are designed for everyday workshop use and are extremely effective with removal of discoloration, heat tints, and oxides on stainless steel surfaces after TIG and MIG welding.

Cougartron weld cleaning machines are built to provide excellent results with cleaning, passivation and electropolishing – without dangerous grinding dust and hazardous fumes from the pickling paste.

We offer portable electrolytic marking / etching machines for stainless steel, mild steel, copper, zinc, brass, aluminum, and titanium.

The systems are lightweight and ideal for smaller production environments. They also come packed in practical carrying cases for easy off- and on-site use.

Use our machines to easily mark and etch logos, product names, part codes, and serial numbers.

Suitable for dark/black and white etching & marking.

Purge ‘n’ weld bungs are designed to create a perfect seal during back purging and will improve your weld quality. 

The bungs are built from quality silicone to withstand high temperatures in close proximity to the weld and are supplied with a diffuser for the best gas coverage.

The best approach is to actively clean and passivate only the part of the surface that was actually affected by the welding process. This in all cases includes the actual weld and the heat-affected zone.

Unlike grinding, this cleaning method will successfully remove all dirt and discoloration from the welds. This is especially important for successful restoration of the passive layer.
