Setup of HF 251d-1 on Trailblazer 302d

[Mwelch3d]

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.

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?

And try the 251 on a different machine.
