Ha, that's fantastic. Your welds are going to look much better after a few hours of practice. To keep stuff from warping away from each other apply a few tack welds (just small welds without filler, like that one you were pointing out at 13:46, but like a 1/16" wide). I was using a coworker's Chinese welder for aluminum (AC capable), and kept on getting instant contamination of my welds. It turned out the gas lens (the pink ceramic thing) was really off center, and the argon flow was actually sucking in air. Might be a good idea to make sure the stuff in your torch is all concentric. I also have the welder we use set up for 4-touch on the finger control: press down to start argon and strike an arc, but only at 1/2 power, let go of the button to go to full power, at the end of the run hold the button to drop back to 1/2 power to let the puddle cool down, then turn off the torch when you let go of the button. My coworker who has been welding for longer than I have been alive uses a helmet like yours, but I am too much of a noob for that and use the auto-darkening one. Might be able to get one on Craigslist for a good price. The wrist strap is a great idea. I forgot to turn off my argon after only a couple of uses and had to drop $100 on a refill. HPLC update: I am back on it now. I got the DAD ADC's 16-bit parallel output hooked into an arduino and am able to send the full spectra at 40Hz (original hardware only supported a max rate of 10Hz). I have also decided to give up on getting the original electronics on everything else to work the way I am wanting them to, so I have decided instead to rip all of the original control hardware out of everything and put in my own electronics. The HPLC will have some modern features by the time I am done with this.
I'm lucky that the refill for me is only about 40$ here. and thanks for the update on the HPLC! I think I'm going to target vacuum experiments before my chemistry experiments.
@RinoaL oh nice. I bought a vacuum oven a while back and modifyed it by welding a 3" pipe out of the top with an ISO-100 flange that holds my turbo pump. It works great for freeze drying as I can pull down to 1mTorr pretty easily, and that's WITH a crack in the oven from the manufacturer (it took me a long time to find that crack). I also have a refrigerated cold trap between the turbo and mechanical pump.
It's really nice to see more of you and as always very interesting to see what you're up to. I've never welded with MIG. Often hear MIG is easier, but stick and TIG feels like the way to go. I prefer stick because it works really well outdoors and it is way cheaper. When I use TIG it is for tacking stuff together, but all my indoors setups are too poorly ventilated to really go at it for long times with the TIG torch. I remember your comments on safety concerns from the house restoration period where you dedicated a video to the subject. But still I hope you stay safe and get the fumes away from you.
I was equally as excited the first tank I bought. You should 3d print one of those cap on/off indicators. I had to modify some files to fit the profile of my cylinders valve. I did loose one partial tank of gas due to leaving it on once.
@@RinoaL I've never used a Vevor (those guys make everything), but it sounds like it has high frequency start (versus scratch start). A lot of machines are using IGBT these days. I have an Everlast 185DV. I think it was the least expensive machine they had that could do AC/DC. I had a cheap Chinese plasma cutter that died. No manual. No schematic. No documentation. I tried to fix it by replacing some obviously burnt parts, but no luck.

You looked happy with your cylinder 😊
love your videos rin! keep up the good work

I think for myself I'll actually make a bracelet that I put on when I open the regulator, however I'm extremely good with discipline so we shall see.
An "A" for effort. Practice will bring it home. Be well.
What fun!! Wanna get a me a TIG too! Thank you for sharing!
Does your TIG do AC or just DC? You need AC for aluminum.
Im not actually sure since the manual is a bit scarce
@@RinoaL Vevor TIG machines are only DC
Yeah Im starting to think it is only dc, but maybe PWM or something.
I had somebody offer me a big machine for $800 but couldnt afford it

I still remember the days of you living on tortinos pepperoni pizza
Basically still am, cant afford good food, stuck with aldi shit
@ very interesting 🤔 as always. I think I’ve been a “fan” of yours for a decade which is crazy to me.
Mig is clean flux core is what you've been using
Most people know it by mig though, and thats how its marketed. MIG just means any wire welder now.
@RinoaL yeah I find that aswell
NICE!
