cha-ching...quarter rolls into empty box.
So just a day or two ago I was given some 1" (25.4mm) square steel tubing and then later that day my backwoods fab friend (he makes firewood splitters these days) comes in with a tiny little stick "welder" and a handful of 1/16" welding rod (so effing cute). The thing has two settings: low and high with "high" being 70 amps, that's it. I say, "That must be a switcher" and he doesn't get, but I don't attempt to explain (he's 70-ish and learned his wiring back then). But I have plenty of experience with "switching" power supplies in the radio field, to wit: they're small cheap light and VERY VERY RF noisy. A horrible bad thing for radio. But it _is_ the current rage and how you get a ton of DC amps w/o a big heavy transformer. (pun effing intended)
He plugs the shrunken "welder" in, attempts to strike an arc and it goes something like this: Sput SPutter fiZZ sTick sputTLE, pause, CUSS FUSS mumble spit grumble. SO seeing my chance and noting that it runs offa 110 (as I happen to have some new steel to play with) I say "Yo, let me go try it out."
And he quickly agrees, glad to be shed of it.
Today as the blustery chill of morning kept me from roaming far, I burned about half the rod supply that came with the little tiny welder - with two whole settings. IF the metal is very clean and you keep nipping the end of the rod and you damn near keep the tip buried in the puddle and a gnat doesn't fart too close to the arc, THEN it'll work somewhat. Forget low power, almost impossible to start and no penetration 'tall. It could be an old/contaminated rod thing, but it absolutely will not never, ever, nohow re-strike on a rod without nipping the end. No id on the rod, but that was the most impossible to run combination I've ever laid hands on.
I made my project (no you can't see it), but could have brazed it faster--or gas welded it with coat-hanger for cripes sake! Hoping to get more of the free metal, but don't want to run my gases low before next bike or two.
Forgot how nasty stick welding is...shop needs a clean up anyway.
So if'n you see a pocket-sized welder and think "Wow, that's cheap and cute and I always wanted to learn to weld"...fugget about it--really, I can't imagine how frustrating that thing would be to a noob. If you don't think I know what I'm laying down here, try to find one at a yard-sale or CL. That part should be very easy. MOF, I feel confident that Bobby will sell you this one for 50 bucks plus shipping.

In hindsight, I should have tried some fresher, albeit "oversized" rod with it. meh...
