I'll give that some thought. I could probably provide samples of carbon and 304 stainless steel cut with plasma, carbon steel and possibly cast iron cut with oxy-acetylene, and weld spatter spherules from carbon steel and 304 stainless. Perhaps slag from SMAW welds of various metals (these will cont...

Boy, are you in for a surprise.

Tell me that bullshit in twenty years, when you've finally realized just how much you don't know yet.

In extreme cold, gas engines start easier. In hazardous locations, diesels are preferred (including your truck, which you already have covered). If you're going to rig up, buy the most versatile machine you can afford. Look at what you can do, and what you'd like to do in five to ten years. A rig is...

6013 and 6011 are both AC rods. (Both will run OK on a DC machine, electrode positive.) 6010 is a DC rod.

I'm not a fan of harbor freight products if you rely on your tools for your income. However, I have nothing against buying from them for hobby or practice needs.

In your suggested repair, you will get more ultimate strength welding the sides INSTEAD of the areas you've indicated. Welding the sides gives you strength in tension. Welding across the web introduces two HAZs, and without welding the sides allows a lot of flex in the joint. Repairing the holes isn...

Yeah yeah, I get that - but why's there never any chunks of coal in the slag? I'm assuming the slag was 'made' in the furnace, and not brought in on the truck that delivered the loads of coal. Is it because all the coal is burned off before the slag had a chance to accumulate? There's still coal in...

Gotcha.

Up a bit late, rather than really early.

Nice work on the drawings! I have a similar freeware cad program, but I have yet to experiment with it.

Thanks for the language lesson, too. I believe I understood it completely.

I had it close in my head, but, in the English custom, I wasn't pronouncing the second "e".

Coal is sedimentary in nature. Layer upon layer of organic material accumulating in swamps and bogs, easily inundated by floods, tsunamis, etc. There are a lot of things in coal that are not carbon, especially low grades ( cheap) so the "clinkers" can have all sorts of mineral content in t...

...In Norwegian it's called "tralle" (welding cart = sveisetralle), so I guess that's why "trolley" was the first word that came to mind. Ståle Sveisetralle.jpg Can you give me a reasonable phonetic spelling to pronounce that (sveisetralle)? I love to learn new words! I'm guessi...

I realize this is an old post, but it's a good question. Strip the flowmeter from a regulator/flowmeter (They're usually set to 60 or 75 psi, so you're dealing with inrush from this pressure) and place it in line between the solenoid and the stinger. Or, Install the flowmeter component on an adjusta...

Wobulate, I just noticed the time stamp on your last reply. What time zone are you in? I thought I was an early riser!

(This reply is duplicated on the TIG forum.) You would think so, but no, not really. The molecular motion (heat) that keeps it a gas keeps it pretty well diffused. CO2 is heavier than Ar, of course, so there is a variation in the ratio between the top and bottom of the cylinder, but as soon as you b...

I mentioned the flowmeter because another poster was having a similar (but worse) problem. Simply introducing the rod into the gas flow drew air into the puddle and immediately oxidized the puddle. He tried another flowmeter, and voila, problem solved. In calm air, it takes very little gas flow to p...

(I pasted a copy of this reply to your duplicate question on the MIG forum.) You would think so, but no, not really. The molecular motion (heat) that keeps it a gas keeps it pretty well diffused.

This probably doesn't apply, but I encountered yesterday and thought I'd mention it. A fellow was making a simple repair on 1/4" Al, and was having trouble. He was using a Miller Syncrowave 250DX. I finally noticed, while he had the machine set on AC, He'd left it on "HF Start", inste...

All new to the forum, so I should warn you that my native language is Norwegian (which potentially could cause misspellings and unintentional poor orthography).

English is a second language to you?

I don't believe it. You write English far better than most speak it.

So you're using a regulator set, instead of a regulator/flowmeter? It sounds like my guess about gas flow was pretty much on target. (And it was a guess!) What's your city/state? I have access to dozens of used flowmeter sets, and could send you one for the postage. You'll use a lot less gas when yo...

I've used saws like this, both wet and dry, and was impressed with both.

The blades are not inexpensive for either. Let the tool do the work. Don't get impatient and push the saw.

You'll be pleased with the quality of the cut.

... When I finished the bead there was an indentation in it at the very tip. Is that correct. I was welding two pieces together. Thanks, Bill Perfectly normal. What you do here is called "buttoning off/up". When you reach the end of your weld, stop, pause and let the color of your puddle ...

I taught myself to weld when I was thirteen, and have been learning ever since, so I can't speak to the experience of formal training. The welding "bug" bit me early, and it kind of got into my blood. I've tried many different jobs, in very different career paths, and I've always come back...

How much gas flow? With too much, it's possible pushing the rod into the flow is creating turbulence and mixing air in at the weld, even drawing it along the backside of the rod. In calm air, 10-15 cfh is plenty whether you're using a gas lens or collet body. The only time I've needed more than 30 c...

Lookin for the maxstar 150 or 200. Where did you see em for 800? All the ones I seen were around 1000. Probably half "where", half "when". I was on an industrial job, and because of the volume of consumables and gasses we were buying, They were offering the hands some sweet deal...

How portable? Miller makes a 120/240v. DC inverter. If I remember, it weighs under 20 lbs., and comes with a shoulder strap. It'll handle around 150A @ 20% duty (again, I'm going from memory, your mileage may vary). I used one @ 90A on 2" Sch 10 SS, several welds, and it never shut down from he...

BUZZMAN4177, I hate to ask what's probably an obvious question, but you're using AC high-frequency (and you know it's working), 100% argon? Are you certain of the alloy of your base metal? With the cleaning you describe, the gas flow, and the fact your puddle forms normally, something doesn't add up...
