It appears to be AC only, 30-180 amps, so similar to a lincoln "tombstone" except it says craftsman on it. I'm sure it perfectly servicible (there is nothing to break), but since its fairly limited capacity and only AC output, its fairly limited in what it can do, and that limits the market...

I have seen procedures for stainless MIG, but i'd agree with Dr Clyde, 1/16" is pretty thin for MIG. Gas wise I would use 98% Argon, 2% O2.

You would measure 20A on both L1 and L2. The current is flowing from L1 to L2 during one half of the cycle, and reverse during the other half.

First off I think its a cool idea and applaude you guys for taking the leap and putting something out there. I agree that its great to have an American company making tools, even if the machining is accomplished overseas, you still control specifications and QA. This is way in the weeds, and...

Agreed - in certian conditions copper will take on a greenish patina, but thats all I would expect unless its exposed to a highly acidic atmosphere.

As many have said, being a mechanic and having an engineering degree are not mutually exclusive. So I don't lose your attention, I am a mechanical engineer and overhaul certian ships painted grey and black that don't need gas. They are hands-down the coolest pieces of machinery in the entire...

I would suspect its normal, unless its on all the time. I have a heat pump system as well. Because the heat pump "moves" heat from outside to inside, your outside unit gets really cold during operation, and can accumulate a lot of ice if its humid outside. When it ices up, the heat pump will...

Has the transfer switch already been installed, or will be installed? You'd already have the power off to do the transfer switch. Otherwise, you need a way to isolate line power to the transfer switch so you can wire up your indicator light. Main breaker upstream of transfer switch?

I think you've got it in the right spot in the third picture of your OP. I have something of a thing for mid-century fluorescent lamps, and they almost all use what's called a "switch start" instead of a capacitor type or electronic starter. They are great because there is almost nothing to...

east_tm_emc beat me to it, but I would check into the voltage issue very carefully before you get too far. We can probably tell you what you are into with a picture of the tag on the generator head. I agree, almost certianly a well-built unit, but that was the first thing I thought of when he...

Ok... you guys have converted me. I started writing this post to say y'all were out to lunch and the numbers didn't make any sense. But now that i've done the numbers, I stand corrected: For the T8s fluorescents: 50 ten watt bulbs = 500W power consumption. At $0.11 kW/hr, thats $0.055 per...

Whenever this topic comes up, all of the objections focus on two key points. I'm pointing out some stuff that should be obvious, but for those without a lot of electrical knowledge, its not always so obvious. 1. More often than not, the suggested hook-up is with a cord with male plugs on both...

I'll give this a shot... You've got the right idea on the breaker, its a double breaker with the two handles tied together rated for 60A. I would say that since the manufacturer has spec'ed that as the overcurrent protection for your heater, that's the right thing to do. I agree its a little...

I am an engineer as well, I agree with what most have said, which is "you need an engineer" The multi-level part should be fairly straight forward. We had essentially what you are looking for in our old house where the actual garage was supported by poured in place concrete walls on two sides...

Bunch of folks have mentioned two things here that are true: 1. I would not be concerned about shorting the welder as long as you are careful with the duty cycle, which will be listed in the manual. A stick or TIG welder is, by design, a "constant current" device, so its always going to output...

The problem with this setup is that the interlock is designed to only allow you to use one source of power at a time, so when you are on generator power, the shop panel is isolated from the house, therefore no power back to the house. But, you'll be sitting pretty in the shop :rocker: The only...

IMO, for the applications the OP lists, cordless drills have compleatly replaced corded drills. I also agree the OP needs a drill, not an impact driver. I like my impact, but its a specialized tool that really only meets its fully potential in trained hands. And with how inexpensive the M12...

I could be mistaken about the 250, I should caveat that I'm basing my information on a thread I read over on the WeldingWeb forum that is almost 2 years old, where someone thought $800 was a good deal on a Millermatic 250. If you can get a hold of the serial number, this chart...

I'm going to agree with zkling on the Econotig... too limited on power. You should be able to find a used Syncrowave for $1000 that is a vastly superior machine. If the second is a Millermatic 250, thats a MIG only machine. If you are tying to TIG, you're out of luck. Its also an older model...

That setup sberry just posted is almost exactly like what we use at work for pressure tests on all sorts of stuff, anywhere from 15 psi all the way up to 4500 psi. I believe our procedure calls for a relief valve set 10% above the test pressure. Nearly all of our tests are "no leakage...
