  • Miller tig welder model hf-250-1 high frequency arc starter

    Could I set up to tig weld aluminum with this off a bobcat 225 ? Would it be a good way to do it or not worth it ? Probably could buy it for 500 . I don’t have a torch or bottle or anything for tig would have to buy that separate.

    Possible, yes. Practical, no.
    Unless there is something I have forgotten, you would not have any provision for a pedal or thumb control for your amperage. Not really a big problem for mild or stainless steel. However, it will be a problem with aluminum.

      You could, but you won't have any current control, which makes it a lot harder - the bobcat has no connection for a foot pedal. If your hf-250-1 unit isn't equipped with a contactor, you'll have to break the arc by lifting the tungsten. $500 seems a bit high for an older arc starter.

          I’ve done what you had planned, only I added an on-off switch to the torch. It would get you by in a pinch, but that’s about it. The advice given above is sound and the advice given to me was I’d be better off running another welder off the genset.

            Yes there are a lot of cheap AC/DC tig welders I’m just a hobbyist wouldn’t use it much.
