  • Tig welding with my Bobcat

    I'm looking to get my Bobcat welder set up to tig weld on. Will an high frequency box help with a/c welding? I really don't want to buy a whole other unit jus to a/c tig. I see lots of newer high frequency boxes on ebay for sale . Any help will be greatly appreciated.

      Even with an HF-251 HF box ... the Bobcat makes a pretty marginal AC TIG machine....

      does not have the ability to run a pedal or contactor... Scratch start only....NO 14pin connector... like a Trailblazer

      Would suggest if you are serious about TIG... that you invest in a dedicated... full featured machine like a Dynasty...
      .

          The Bobcat does NOT have the 14pin control connector required for remote amperage and contactor control...

          BUT the Trailblazer does... so it can use the remote capabilities of an HF-251 as well as pedal

          Unfortunately... Miller no longer makes an AC/DC Trailblazer.... a used TB301 or TB302 would work...

          However...a dedicated TIG machine is still a better bet

            I have welded aluminum on AC a GREAT DEAL with a Bobcat. It's ok. Bobcats are a wonderful generator. The arc itself is sufficient to give satisfactory results. The torch will always be LIVE. You will need a gas valve on your torch. You will have to set your amps on the machine quite frequently. It is a very basic setup at best, and very cumbersome to implement.

            When you master this and move to a better machine you will be much happier for sure.

            If you were to buy a small Dynasty such as a 200 or 210, or even a 280, and run that off of your machine, you would be very impressed with the results VS the arc off of the Bobcat itself (or a Trailblazer for that matter)
