    I use only ss brushes and as far as the tungsten goes I have never had a problem. Where I worked everyone ground their tungsten the same way and I don't recall anyone complaining of tungsten sputtering or the arc wandering. I still tig in my garage today and grind my tungsten the same way. I mostly tig because wheelchairs and sparks dont seem to get along but still stick weld from time to time.

    Default tungsten

    Tsalagi I never have had a prolem with the arc wandering or sputtering and where I worked for 28 years everyone ground their tungsten the same way. It was the only way we were ever taught. As far as the wire brushes I use only ss for everything. We sharpened tungsten to a pretty good point and went to work and only had tungsten inclusion in the weld if you stuck it and failed to grind it out properly. Rarely seen tungsten flake off.

    Thanks

    Where I worked we always grind across the tungsten. I We just roll it around the grinding wheel the way you would roll a Q-Tip in your fingers. This was the way we were taught and we used it on nuclear pipe on submarines and all other pipe. I guess everyone has a way to suit their needs. I hope this clarifies how it worked for us.

    Thank you

    thats odd, this is the first time i have herd of it being an exceptable methode to grind acrost the tungsten?? i supose it may not be as critical as one would be lead to believe, just the same i think i'll stick to grinding in the direction of the tungsten, its how i lerned.

    Default tungsten grinding

    Back when I first started to tig weld I didn't have anyone tell me the right or wrong way to grind the tungsten. I started out grinding across the grain and did so for quite some time until I was told otherwise, Me personally I couldn't find a difference in the welding or arc either way it was ground. Dave

    anyone here use the white powdered crystals for sharpening to a razor point. I bought some and it seems to work excellent and quickly with little waste. Just have to + the electrode to heat it up red hot and dip , it then turns to liquid and sizzles off the contaminated Tg and sharpens to a perfect needle point no matter what shape it was in before the dip.

    i havent tryed it personaly, but want to some time, just keep forgetting to get some when at the LWS.
    i have herd it makes a nice point but you do need to wach it to keep it from eating up too much.
    i always wonderd how do you heat the tungsten to use the dip??? just have a long stick out and spark an arc??? but that would seem to contaminate it in the air??? how hot dose it need to be and how do you heat it??? all this info is probly on the jar, i just never remember to look.
    thanks for the help

    they do cover the grind direction isu though, if they set up a $2000= grinder to grind with the direction of the tungsten towrd the point, it must be the best way to do it. only thing i can see this guy saying grind sideways for is it might be safer from a kickback point of view ?? but i suspect its a typo, again a letter to the editor would be in order if ya ask me.might even get ya a free subscription renewal out of it.
    I was actually going to start a thread about grinders one of these days, but this one seems to be on topic, so I'll ask here. I have read up on the PII and PIII grinders, and also the DGP series, and had to ask, are they worth it? I've heard a couple ppl mention they have them, and I believe they were happy with them, someone even upgraded from the II to the III, if I remember correctly.

    Is the opinion that these are worthwhile, as they are fairly automated, and take care of the dust as well, or are they more for a production shop environment?
