Have you tried autogenous welding?

I’m excited to see where this goes, really hope we get a lot of entries!

Nice cart Jeff!

Don't know anything about Rapidarc but it looks interesting. Care to share any more success/troubleshooting/issues you have had with it?

Welcome Rick. What tig welder did you get?

Happen to have any updates on this? It is situations like this that I started running a gas mixer and bottles of single gas. That way I am not locked down to any one mix of gas. Very likely this wire requires a spray transfer and can't get there with 75/25.

Jeff Loffert A fellow Alaskan! I suggest going with the 30a rather than the 15a. If you ever use it on an engine drive welder, 30' isn't as long as it seems it should be. Or if you poke it outside a garage door or something, 15' is short. The other advantage of the 30a is if the cord ever gets damaged, a guy has extra cable there to be able to chop down and repair and still have a chance at leaving some length.

That machine has the benefit of not needing the wire feeder ($$$) to use the push pull setup, but that comes with the extra hassle of swapping the spools for sure. A spoolmatic 30a is around $2000 (15a is shorter aand a few hundred less.), the XR-alumapro lite push pull gun is around $2500. So the spool gun is also the cheaper option. My experience tells me that the spool gun is often the best place to start. I also look at it this way...If I have a spool gun, I may be able to go out and do a job I couldn't have before, and sometimes one off jobs are more than enough to completely pay for assets for that job (like an engine drive welder you can run the spool gun off of...for example) that now allow you to do more of that work in the future.

On that machine you can utilize the pulse features with the 30a spool gun like mine, as well. You won't need that control box I showed on the end of my spool gun either, it is a direct hookup to your machine with the 10 pin cord.

😬😬

I have been wanting to try this.
