In Tucker CleanJet TH539, the gas weld head has an attached cleaning device that spot-cleans the surface with plasma just prior to welding, leaving behind a prepared surface ready for welding.
Tucker CleanJet is based on a Tucker gas weld head with an additional plasma torch. In welding position, the Tucker CleanJet torch ejects to prepare for plasma cleaning. After a circa two-second cleaning period, the surface has been prepared ready for welding. The torch automatically retracts while the head moves to the front position for welding.
