    Default Dedicated wheels fror grinding electrodes

    How important is it to use the grinding wheel for tungsten only ?

    I am using the wheel for drill bits also.
    Am not preasure welding pipe, only playing around with home projects , so losing a percent or two of strength is not a big deal.

    Also the owners manual suggests diamond wheels, the cheap aluminum oxide wheel seams to work fine. Is this a bad idea ?

    Thanks

    Default dedicated wheel

    It is very critical when you are doing code welding, but if you are like me, i do minor aluminum repair, boats etc.,thin sheet metal and such you should be fine. I bought me a small cheap bench grinder and it is only used specifically for grinding electrodes,the tungsten grinders are very expensive . Although it mite not be a good practice but it works for me!

    shade tree welder is right you must use one wheel of your tungsten and use it for that purpose only. cuts down on many arc stating and weld bead problems.

    Sounds crazy, but a flap wheel or a sanding disk makes a pretty good sharpener on a disc grinder. and you can dedicate it to just that. Hopes this helps, Paul

    Default Grinding Tungsten

    Take the advice of the pros - dedicate a griding wheel to your tungsten. I went to Harbor Freight and bought a $19.95 grinder for that purpose. If I ever get to the point of second guessing experienced welders - I follow their suggestions.
