We have Messer profile cutting machine. It is in operation for last few years. Recently we are facing problem. The solenoid valve coil connected to gas console (Hiperther make)burns out with in few hours continuous. This solenoid valve is used for control to air, O2, N2 combination. The solenoid valve operates at 110V AC. (make Norgren)
We have cleaned air /gas manifold, removed all pipes and checked seals (soloneid valve seat) checked voltage supplied & current. Current specification is 0.2 A, where as current recorded is 0.8 A. Could not find out reson for high current.
Any one can help to resolve the problem
