    Default Trailblazer 302 and Aluminium TIG???

    Hello all, my first post. Been reading on here for a while and decided to join in!
    I have a 2008 Trailblazer 302 an Id like to know if I can do aluminium tig with it, with or without any attachments. Im looking to go the cheapest route possible as it wont get used often.

    Use the machine in AC and hook up an HF251D1 high freq box, pedal, torch and argon and you'll be tig'ing aluminum with your Trailblazer.

    Sure, but you'll have a real unstable arc that'll wonder everywhere.

    You need the continuous high frequency to run it in AC for tig'ing aluminum. That's what the HF251 box provides, as well as a gas valve that operates via the remote, which is nicer than a manual gas valve on the torch.

    Alternatively, you can just buy a portable inverter tig, like a Dynasty 200 or Thermal Arc 185 or Diversion and plug it into the Trailblazer's 240v outlet. I use my TA185 with my Bobcat to tig aluminum from the truck and it works very well.
