I just spoke with Jeff at USA weld this morning and what a great guy! he helped me decide what accessories to get and actually talked me out of several things that I wouldn't have needed. this thing looks really well made and for the price it's the best bang for the buck that I could find!
darin amann I hope you told him you saw the video. They are the best company out there in the class bar none

I sure did!
Sweet thanks for the answers. I put a down payment on mine last week!
Hi Jim. I start to practice sanitary pipe welding. The only issue that I'm having is that in the exits I'm leaving a pinhole. I'm using my htp invertig 221 in 4t mode with a momentary switch
Hello Harvey. This is a problem that weldors have faced forever! The problem usually is that as you are welding a closed space, the pressure builds up inside and the molten metal cannot create a strong enough seal so as you finish the weld, and the metal begins to solidify, the pressure internally will always find a way to escape (hence a pinhole or in the worst case a blowout). You must find a way to purge (assuming stainless) the interior of the pipe while allowing a method for the pressure to be relieved. This usually is in the form of a separate argon hose flooding the interior of the pipe while leaving a small space for the pressure to escape. Think of taping the end of the pipe closed with a small hole in the tape to allow for expansion. Good Luck, it will work, just need to take some simple precautions.
@@JHV166 thank you so much for the help 🤝🏼
@@sgr5287 best of luck. Keep studying\. I HIGHLY Recommend you pick up a copy of "METALS AND HOW TO WELD THEM" YOu can get it on AMAZON and with a little searching, there is even a copy available online for free (EPUB_//
does the htp cooler for this machine have a small radiator and fan too or is it just the tank and pump? does it come on when the machine comes on or do you have to turn it on separate?
I also heard the torches are ck which would mean you can get parts everyware. Could you confirm that?

Starts by pulling numbers right out of his ass. This machine will handle 99% of what you are going to do in your shop. I guess he can reads minds. I did preheat for 2 hours yesterday so I could weld some 5" plate in multi pass at my home shop.
