My 125 CF Tank is down to 700 psi, is it time to switch it out?

Theres a Chinese 300$ plasma cutter in pieces in my garage. Friend gave it to me. It looks like a High School electronics project inside. The power supply part of it is bad, and the HF start on it never worked. Funny, it never had a ground wire for the power supply.. Piece of crap. I bought my John ...

Sorry, no pics.. Welded up a busted rusted John Deere mower deck. The welder went a decent way for paying for itself. John Deere eh I think they make them cracked :lol: I bought mine second hand and yep in the last 2 years I've had the deck out of it twice, which is more often than I've changed the...

Thanks guys, I will keep you all updated as things eventually progress. Yes, that TV show "Road Kill" is responsible for all of this, and I did buy that book on Chevy small blocks!

I really want to keep from going off track on this, but my first step in this is not welding related. I think this forum is full of like minded people that can help with advice? I want to rebuild a small block Chevy 305/307/350 on the cheap and mount it to an old Volvo 240 to create a LeMons 24 race...

Not that it matters, but 1018 is usually Cold Rolled. Hot Rolled will have a mill scale, and the dimensions are not as true.

What should I look for to improve upon? Straighter beads, better taper off at the end?

Gentleman, I am happy with my gas lens and welder, thanks for the help. I just did this fusion weld, no real prep has been done other than a fresh bandsaw cut. My electrode is staying shiny, and now I am getting colors!

Hello, I went home after the last trip and did a couple of things. First thing I did was install a higher quality potentiometer in the foot pedal, and tweaked it so the lowest point it turns on, gas is flowing, to protect the tungsten, and I stopped using the stubby cap on my torch. Turns out, the c...

I did not clean the pieces before welding. The zinc coating on the table, that was from when I first got the table and welder, and discovered quickly my error. I welded the pieces on top of a 1" thick aluminum block. In the photo, they were placed for a quick photo after the fact.

Clearly something is leaking. I know for a fact that my feed line has a very slow leak, but I doubt it would cause my discolor. In the mean time however, here is my build log for the locomotive I am building. The pictures show some fusion tack welds I did with my stock 17 setup, and also some crappy...

None of my welds with cold rolled 1018 ever have had the pretty colors. Always a dull gray. I am on the road right now, won't be until Tuesday that I get to try to play with it again. My tig cup has no Neoprene washer, just that white plastic heat sheild

Very odd, WJH. as a noob (still am) I welded with a conventional collet body for a couple weeks, then switched to a gas lens. Overall, better, smoother arc, and eventually I turned my gas flow down just a tad, too. Is your lens good and clean? Kym Brand new, USA made. I only had a few minutes to pl...

In Tampa, FL, I pay about 40$ to swap out a 125 CF tank

I've been enjoying my stock size 17 torch, able to do what I needed with it. Recently I purchased a stubby gas lens kit for it, and discovered that I need to re-learn how to tig weld. First thing I noticed was that the same regulator setting was causing the arc to be "blown" for a lack of ...

If his welder is an inverter, won't a tighter arc = hotter? The opposite of a transformer welder?

Zank, do you serve a niche market, or do you have more work than you possibly can handle in a 40 hour work week? I went to your webpage, very impressive, as is your welding!

So I had another idea along with increasing the frequency... I was wondering if I could add a 2nd frequency setting on the display (e.g. "Hz 2") and this would basically add a second frequency only on the peaks of the generated wave. Here is an example illustrating this: http://www.jattus...

Basically, I see an 8$ micro processor spitting out a PWM signal to control the foot pedal input. Emulating pulsing with the foot pedal with precision. Interesting idea, one could do this with an Arduino and a few extra parts. If it's so simple, why don't you make one yourself..... Yeah, that's wha...

Guys, I am speaking from the "do it yourself" crowd mindset. Never said a home brew system would look anywhere as good as his unit, and certainly not be tested, packaged, engineered, AND supported like his product will be. I want to see his product do well. With that said, a PWM signal wit...

Hello, my name is Bill, and I am a hobbyist welder. I own an Everlast 160sth, and so far have only done TIG welding. Currently building a 1/8th scale diesel locomotive, and I have a small lathe and milling machine, along with a 20 ton press, bandsaw, and other tools. I am pretty good with CAD progra...
