Premature consumable wear in Ohmic sensing machine torches.
Lincoln Electric Cutting Systems has experienced premature consumable wear or electrolysis in machine torches that use both a negative ground path (cathode) and positive shield cap (anode) when sodium nitrite is present as a corrosion inhibitor in CNC plasma water tables. Electrolysis occurs when water containing sodium nitrite is introduced to the torch via splashing or submersion into the water table
As a result Lincoln Electric Cutting Systems has removed a feature originally built into the Ohmic sensing of ACCUMOVE to mitigate this chemical reaction via the addition of a relay. The additional relay will be provided to ACCOMOVE 2 and ACCUMOVE 3 machines delivered before December 15, 2015 free of charge.
