The WeldBrush product arose from the need to solve a weld cleaning problem on highly processed engraved panels for McDonald Restaurants. The original process was invented in Italy some decades earlier, but utilised a bulky fabric over a flat electrode which was slow and awkward. A faster solution was needed.


Bill Bunting who, as an industrial designer, knew of the electrical properties of conductive fibres and quickly created the first conductive brush for weld cleaning. As pressure from other businesses wanting access to the brush grew, Bill Bunting created a company with a design associate and an “electronic” engineer to manufacture this brush based weld cleaning machine. This business became Ensitech. However, the partnership failed and Bill Bunting moved on to continue producing and selling his further developed original weld cleaning machines under Keztek and WeldBrush brand names.





With a program of steady product development over many years the WeldBrush has maintained its position as the most versatile, powerful, compact, robust, preferred weld cleaning machine standing out from a very solid field of competitors.
