Looks like I'm late for the party. Congrats on the Everlast 160sth purchase. I've been going back and forth trying to decide between the Everlast 140st and the Everlast 160sth since December! I *thought* I had decided on the 140st until I read this thread. LOL :laughing:
I can sympathize, having been in your exact shoes for about a week before I made my decision. The 140ST is substantially cheaper than the 160STH. One thing to think about is that the 20 extra amps of the 160 will make a difference with some 1/8" 70XX rods, many of which are nominally rated to run at 110-165 amps. The Blackstone 7018 that I have says 90-155 on the box, so there's some variance between brands, and of course you don't always have to run the rod at the top end of the range, but I don't think there's any question that the 140 will fall short on some 70XX rods, in some circumstances, whereas the 160 will be able to run any 1/8" rod, in most circumstances.
Of course, what makes the 160STH stand out is the pedal and the HF start, and only you can decide how valuable that is to you. As Shield Arc pointed out to me when I was shopping, X-ray quality welds are made every day with lift-start. Welding in the field, many weldors who have access to a pedal forego it because how are you going to run a pedal laying on your back up underneath a pipe, or hanging off a catwalk, or what have you. At the same time, no one who I talked to said that a pedal was a bad thing, and most/all said that, at the bench, they considered the pedal to be a must. When you think about what it would cost you to get into an Everlast TIG machine, the PA160STH starts to look like a real bargain. It lacks many of the features of the dedicated TIG machines, like pulse, variable balance, and so forth, but I think that's kind of icing on the TIG cake. A pedal, a gas solenoid, and HF start are the bread and butter, IMO.
At roughly the same price as the 160STH, you can get a PA300. The PA300 has far more output than I ever anticipate needing. It can run up to 1/4" rods. Woo hoo! That's nice, but it's kind of pointless for me, because I seldom weld material thicker than 3/8". What makes the PA300 stand out is the adjustable arc force and hot start. Given that it's roughly the same price as the 160STH, you can ask yourself which you'd rather have: HF/pedal TIG or adjustable arc force/hot start (and an extra 140 amps output sure, but like I said, that's kind of pointless for me, and maybe it is for you too). I wasn't sure whether those features really ought to be worth very much. Surely the automatic arc force/hot start on the lower units is fine, right? But others were adamant that those features were more than worth their price compared to, say, the PA200, which doesn't have them. So if I was going to think of myself as a "pure stick" guy, I might choose the 300 over the 160STH. And if I wanted to, I could always go scratch-start TIG.
Of all these units, the PA200 seems a bit like the red-headed stepchild. It's more powerful than the 140 and has a dedicated 6010 port, but it doesn't have the fancy TIG features of the 160STH, nor the adjustability of the PA300. Sure, it's cheaper than the PA300 or the 160STH, but not by
that much (IMO, of course), and it seems like somebody who was considering the PA200 might just as well drop down to the PA140ST and save a few bucks or scrimp a little more and step up to the PA160STH or the PA300. The fact that the PA140ST has lift start and the PA200 doesn't gives the PA140ST a little extra in its favor, to make up its lack of output compared to the PA200.
Even further complicating the issue is the fact that Mark tells me they're coming out with a PA200ST and a PA300ST soon. If I understand correctly, these units will be comparable to the current 200 and 300, but they will have lift start. Now that is pretty sweet. The ability to have the extra output/duty cycle of the 200 without having to give up lift-start? Nice. I don't know what your purchase timeframe is, or when these units are expected to be available, but they may be worth waiting for.
