*** A series of tips I sent him...
Wireless foot Pedal - I might consider buying one of these. My foot pedal cord is really annoying. I'm already managing the torch cable and ground cable, it seems like I'm frequently having to bend over and reposition the foot pedal and cable, one less cable would be great.
TIG Mistake Eraser - One thing you will love about TIG is if you mess up, dip your tungsten and flame out, lay an ugly bead, forget to put your ground clamp on (face palm) hahaha I have made all the rookie mistakes. Whatever mistake you can weld right back over the top of your mistake, wet it out, dab a bit of welding rod and its like it never happened. See these beads, each of those beads had sizeable tack welds but you would never know it. I put those beads down after maybe 1 hour of practice TIG is that easy at least with my machine.
Shrinkage/Movement - Metal will move, shrink, warp towards the heat and this is especially true with TIG. With the machine making TIG welding so easy I think you will find managing and designing for the metal moving to be the biggest challenge. I was talking to a pipefitter about this and he said that's the difference between a 2nd year welder and a master welder, they know how the metal is going to move and adjust for this before they weld. These pro's will setup the parts intentionally out of square knowing the heat is going to draw them back into square as they weld. I saw one video where the guy was using a can of compressed air to cool the joint to pull it into square so there are tricks and techniques. But managing the movement extends all the way back to your design even. See the pic above, there is a design flaw that resulted in about a 1/16 inch pull out of flat, had I designed it just a bit different it would not have been an issue. And I had methodically tacked welded this up to limit movement and it was fine, and its very heavy 3/16 inch wall 3x3 tubing, but the full beads pulled it out of flat.
Welding Helmet - I started with a $99 auto darkening helmet but it had limited viewing area and no matter how tight I adjusted it it kept falling off. So I purchased a Millar Digital Infinity helmet, it has a huge viewing area and a new design head gear that was a big improvement. A skull cap helps further with the helmet slipping and protects your scalp.

UV Light - FYI these TIG welders put out serious UV you have to keep everything covered up including buttoning the top button of your welding jacket. They will give you quite a sunburn.

Word of advice regarding welding forums since I'm providing links to them...there isn't a bigger group of opinionated and frequently rude people on the web, don't take it personal when these people start in that's just how welders roll.
Also there are a bunch of knuckleheads who run to the forum to bash their machine and the company when sometimes the issue is user error. Here's an example regarding Everlast...there are quite a few threads on issues with Everlast failing to strike an arc. I myself had this problem with my machine, you hit the switch no arc forms and the machine throws an error code. So is the machine malfunctioning or is it that the users tungsten is contaminated or the area they are trying to strike an arc on is contaminated e.g. oxidized? In my case it was the latter not the machine.
IMPORTANT! When I first got the machine I had a buddy come over who had some welding experience. At first we didn't have any problem, but of course the several tungsten's I had ground were all brand new. It was only after we had dipped them in the puddle and started regrinding them that we ran into the issue of failing to strike an arc. It seemed random at first but wasn't, I figured it out in short order. You grind these tungsten's electrodes to a pencil point but not to a needle point, close but not that sharp. On some of these tungstens I had not ground the contamination off the very tip of the tungsten, you are talking maybe .010 to .015 diameter of the tip but it was still there. I noticed this when the machine failed to strike an arc on a tungsten I had just re-ground. I happened to look at the tip and saw that it was still black not shiny. So I swiped the end with some 600 grit sandpaper and bang she struck an arc no problem. We confirmed this several more times and once we made sure to grind off the tip when re-grinding we had no further issues. There was a couple of times when things went wrong during welding and the shielding gas didn't have a chance to keep the part clean, well same deal it doesn't like to strike an arc on contaminated material. I moved to a clean area of the scrap we were running practice beads on and it struck an arc no problem. So I hit the contaminated area quick with a wire brush, bingo. So TIG likes clean electrodes and clean materials, and clean filler rod for that matter. Maybe the Everlast is more picky about this than other machines I don't know but if I just keep things clean I never have an issue striking an arc.

Final thoughts on tungsten. They come in various alloys, I have been using the Airgas brand (Radnor) purple tungsten which they recommended. They said local shops have been telling them those have been working well on both stainless and steel. I have had no issues with them. They come in a few different diameters, 1/16, 3/32, and 1/8. I have been using the 3/32 with good results on say .090 to .180 thick stock. You would go with the 1/16 for thinner stock at lower amperages and 1/8 for thicker stock at higher amperages. Similarly filler rods come in a few diameters. I have been using 1/16 with but its too thin for the 3x3 3/16 inch wall tubing I have been welding, in that poof and you have used up the rod, fillet welds on that tubing take a lot of filler. If you don't feed in enough filler, fast enough it will melt it off the side of the tubing above the weld bead, they have a term for that but I don't recall what it is. So I'm moving up to 3/32 rod and 1/8 rod. The 1/8 may be too thick in that it melts too slow at the amperage I'm using we'll see. Finally the filler comes in different alloys, I have been using 308 for stainless but they sell 316 also but I think they said its more difficult to work with. For aluminum I have no clue I have yet to even attempt TIG welding aluminum.
Metal Moving - I did tack weld that stand with substantial tacks, moving around to different joints not letting any one joint get too hot. And that would have worked fine for when I did the full beads, the metal moving was a design error on my part. That stand has 4 legs, I cut two short legs 12 inches in length and for the other two legs I just used a single length 24 inches long and welded the two short legs to that, this was the design error. If you weld the end of the tubing you get minimal movement, but if you weld in the middle of the tubing watch out, no matter how many tacks you use its going to bow towards the heat. I found this to be true not only on some flat 3/8 thick cold rolled steel but incredibly on this heavy 3x3 3/16 wall stainless tubing. I thought no way the heat could bend it but it did. It bent that tubing about 1/16 out of flat, I ended up having to shim one of the casters to compensate. Had I cut all 4 feet to 12 inches and welded them to the end of the center pole the movement would have been minimal.
Clearly I need to learn more here because when they weld up frames, bicycles, motorcycle, race car frames they are welding tubing in the center all the time so I clearly don't know the technique for doing that without bowing the tubing towards the heat. If you watch welding videos you will see that they use blocks of aluminum and other methods of wicking the heat away. Bottom line there is more to this welding stuff than first meets the eye. UPDATE: I saw on an episode of How its Made they were welding up bicycle frames out of aluminum tubing, here's how the dealt with the welds pulling stuff out of alignment...they heated the entire frame up in an oven to anneal it to make it soft, then knocked it back into square with soft blow hammers and stuff, then heat treated it again to strengthen it. So metal moving, that's going to be a learning curve.
The switch on the torch is the bomb for tacking, no way I'd use the foot pedal for that. Another example of advantage TIG over MIG. When I was tacking with the MIG after each tack I had to snip the end of the MIG wire clean and to length before I could make the next tack weld. That's why they sell those MIG welding wire cutters. Man I had those snipped off ends flying all over the place which WILL by the way puncture a tire, I never had an issue but my brother had gotten some flat tires from MIG wire cutoffs, the steel MIG wire is pretty stiff. With TIG you can just go to town tacking like crazy, just like soldering.
I had wired up a 30 amp 220 twist lock outlet for my Lincoln 210MP and have been using that for the Everlast with no issues. I have not run it at max amperage but I have had it cranked up pretty high with no issues, welding 3/8 thick cold rolled steel. Both Lowes and Home Depot carry the outlets, cord plug ends, and power cord. I cut the clothes dryer style plug off my Everlast cord and installed a twist lock. I considered making a short adaptor cord with a dryer plug end on one end and a twist lock on the other but decided that was silly. I used 10 gauge 300 volt flex cord, a 25 foot length. Nothing even gets warm let alone hot. These inverters are not like the amp sucking old buzz box transformer style welders. If ever the day comes when I need a 40 amp circuit I'll cross that bridge when I come to it. Perhaps when welding thick aluminum I don't know.
