  • Setup of HF 251d-1 on Trailblazer 302d

    Trying to run HF box on my trailblazer and going by the manual I think I have everything setup but am not getting hot enough to penitrate and start a good puddle. Before I start diagnosing problems at the HF box, I am wondering if anyone has a play by play setup with pics or a video of these two machines specifically.

    Well, that was helpful eh? I wouldn't know where to start. I have the same HF box and have never had an issue with it. Maybe try it on a different machine and see if works better? I'm interested to see if you get it worked out because I'm eyeballing the new trailblazers myself.

      HF box is pristine.

      So I opened the HF box and the inside is clean and all connections are solid. Below is a pic. I'm gonna hook it all up again and take more pics of the setup.

      Still looking for advice.

      Thanks all.Click image for larger version

        If it's not getting hot enough to start a puddle that's a function of the Trailblazer settings and not the HF-251D-1.

        Is your hand or foot control good? If yes, even then the hand/foot control signal only passes thru the HF unit and does nothing to or in the HF unit itself to control weld output.

          Pics of setup.

          I have taken pics of the setup how it is currently configured. We have tried both foot and hand control. Setting the amps on the trailblazer to 180 before welding. When I begin to weld the amps drop down to 100 or less no matter what position the foot pedal is in.

            I don't know about anyone else but I can't tell anything conclusive about your setup from your photos.

            Does everything work properly on the Trailblazer if you scratch start DC TIG?
