   It has higher applicable power, delivering more effective amps, which in turn means an extremely fast operation.   The direct current means that the finished welds are electro polished with a smoother reflective finish and delivers a passive layer offering the most corrosive resistance, as proven in University testing.   Importantly the direct current reduces micro pitting problems and contamination created with alternating current electrochemical cleaners that employ a brush.   And finally MIG welds can be cleaned quickly and easily.   Furthermore there are three carbon fibre brush options so all joint geometry can be cleaned with speed and precision.   Sandvik Materials Technology also tested the TIG CHAMP BRUSH DC Plus and concluded that “the electro cleaning can improve the corrosion resistance to a level above that of the original parent metal”.   The unique brushes and the patented fluctuating wave shakes atoms loose for a speedier clean.   The resulting finish meets ASTM A380 Practice for Cleaning, descaling, and Passivation of Stainless Steel.   On top of this it’s a simple setting free operation so operator errors are eliminated.   The AWI  concluded ‘the best method of post weld finishing stainless steel is electro polishing, it increases density of the chromium and creates a microscopically smoother surface” and it can only be achieved with a DC portable machine   Stainless steel weld cleaning is no longer labour intensive, and the weld will no longer be a potential corrosion point.   Get a competitive edge with more corrosive resistant finished work, save time and labour and provide a safer working environment with the TIG CHAMP BRUSH DC Plus.
