Also, if you're welding sheet metal, you'll have an easier time using .025/.023 wire and getting some welding spoons, if the setup permits. Chill blocks, just pieces of aluminum or copper/brass placed next to the weld, might not be a bad idea either. This is TIG welding stainless, but it...

Diamond burr in a Dremel tool. S/F....Ken M

Well, it's got a 3yr warranty and a trial period, so you're not risking much to try it. IME, the Chicom stuff is OK if it's not dead on arrival due to handling or crap assembly. If you're not using it for commercial purposes, I think most people are willing to trade dealer/retailer support for...

What was it doing or not doing? Any pictures by any chance? What are you welding? (material and thickness) S/F....Ken M PS: I forgot to mention, but in case anyone doesn't know, you pretty much always want to run a 'push' angle with the spool gun, 'drag' almost universally fails. If you...

OK, some pointers, hope they help. I assume you're going to use strictly for aluminum or do you also plan to do stainless(get separate liners if you can)? You need pure 100% argon, no other mix will work (with the possible exception of some helium mixes, let's not go there...) Black soot/smut...

IR 2135, about $260 on sale right now. I currently have 3(one at home, one in my toolbox at the shop, one in my toolbag for the truck), had one get stolen while down in the Chitcago ghetto. If that does't take it off, go straight to the 1" drive on a 1/2" airline, a 3/4" will usually just be...

Not to be excessively critical, but what sort of joint were you welding? Even with good joint prep, (beveled, multi-pass), 1/4" is probably not going to pass an open face/open root bend test with only 135amps. Can it be strong enough for it's use? Maybe, good joint design is often more...

If you're just doing automotive and hobby work, I don't think you'll see any advantage to the Miller 211 over the Lincoln. If you are planning on doing a lot of welding on higher outputs, the Miller will be an advantage. S/F....Ken M

Thermal Arc got bought by ESAB and is now Tweco. Miller makes a good welder; however you are paying a premium for the name and dealer network. That network is important if you're doing this commercially and time=money. Everything breaks and getting a rental unit delivered can be a lifesaver...

The Handler 210 is a good transformer unit. In theory, infinite voltage adjustment is better. In the real world, you'd probably have to work to notice it. If anything, you might want lower settings if you're doing thin sheet metal. Transformer units tend to be more durable than inverter...

Well, you can get a spoolgun and use that, it does support it, but I do not have one. I have a Python push-pull gun for my PM300 when I need to weld a lot of aluminum, but I usually just AC TIG with my Syncro 250. 210amps with a spoolgun should be good for 3/16" aluminum. You can weld...

Well, that depends on the joint and the prep. I'd be perfectly comfortable doing 1/8 and 3/16" lap joints all day long using either process. With a 45degree bevel, doing 3/8" multiple pass is no problem. I put those to a bend test all day long. But being honest, 150-160 amps is all you need...

Tweco 211i or Lincoln 210MP. Both about 1000'ish, both dual voltage, both can also do SMAW and lift TIG-DC. The Tweco can run 12" spools, the Lincoln only fits 8" IIRC. http://www.weldingsuppliesfromioc.com/tweco-fabricator-211i-mig-tig-stick-welder-pkg-w1004201-with-w4014603 $1100 with the...

Yeah, it's the intangibles you get burned on, plastic feed assemblies, smaller unsealed feed motors and marginal electrical connections. S/F....Ken M

What do you have for electrical wiring? If you have at least 60 amp 230v, consider a used Syncro or Lincoln Square wave. If less, since you want to do aluminum consider a HTP 221. 40 more amps than the Diversion and not that much more money. Aluminum eats power. S/F.....Ken M

What's the welded base material? The most common TIG filler for mild steel is going to be ER70-S2, which is also suitable for most welding of 4130, such as on some chassis components and roll cages. You can get ER70-S6, which has more cleaning agents, for dirtier metals, but that's a crutch...

Call 'em. They don't list everything. S/F.....Ken M

SSC controls makes great pedals for the Everlast stuff. That's the way to go, especially with the 185, since you have to pay more for the Chi-com pedal. S/F....Ken M

Hobart 140 is good choice for hobby users. Filled 55cf argon/C25 bottle are around $100 and make good portable kit. Bout the same size as a 80CF SCUBA tank. Give you about 2hrs of arc time per fill. Make sure those 120v outlets are at least 20amp circuits and plug directly to the outlet...
