zapped by the tig

admin

Problem... Holding the TIG torch in my right hand, if I have that hand on the workpiece when I trigger the arc it will give me an electric shock sometimes. Does anyone know why?The machine is a Miller syncro running an 18 series water cooled torch and is controlled by a trigger on the torch handle

Reply:In theory, water containing ions, a minor leak, carbon deposit, or a damaged torch could be your problem. I think Jim, or whoever he is is right. Make sure you have good work lead connection at every point it terminates. My table has no thin spot I can easily clamp to. Sometimes the "ground" lead pops off. Then I get zapped. If your table is steel it may build up a layer of oxidation impeding continuity to the work. I suppose hitting the pedal before getting the tungsten close to the work might encourage it. If you sweat in your gloves switch to Ove Glove, and wash them occasionally. Salt build up in leather from dried sweat makes them conductive. One guy I know says the secret to keeping your feet warm in winter is spray on anti perspirant. He uses it to keep his feet dry, thus warm.An optimist is usually wrong, and when the unexpected happens is unprepared. A pessimist is usually right, when wrong, is delighted, and well prepared.
