So somebody at my work place threw away a 2450 hood, it didn’t have its lens or anything, Just the shell & headband. Is it possible to buy the whole auto-darkening assembly to slap into the skeleton? I’m an intermediate welder in Industrial Maintenance, looking to get my own or build this hood up for my personal one.

Thanks for any help in advance.

Unrelated question, but how would someone go about making sure said burn doesn’t bet infected. I know said burn is smaller but that’s gonna leave a deep scar?

Prime weld 225 ac tig, 154A, 85Hz, 30%ac balance, #5 cup with 3/32 cerated tungsten, 13cfh argon.

Bottom is about 1/4" thick vs 0.100 top tubing. Penetration is really lousy, hard to control the puddle, and this white precipitation coming up more than I'm used to. I'm fairly new welding so some user error is built in. Both materials are 6061 using 4043 filler.

Looking forward to learning and your assistance.

I understand they each have different properties but my specific question is when it comes to welding frames on vehicles. Now i understand that mig is the preferred method these days but lets talk old school for a second. I read a lot of different forums online and in some of them you have old timers stating that they have welded everything from heavy equipment to full chassis using only 6011 with no problem. In other places i read that 6011 should be avoided like the plague when doing chassis work. How is it that some swear by it and others cringe at it? I understand that 7018 has higher tensil strength and is used in structural welding but why are opinions so swayed??

I was beveling pipe today. Used an angle grinder for about 6 hours today pretty much nonstop. My upper back feels as if it’s vibrating for the last 5 hours. Could this possibly be related or is there a bigger issue?

Hey, im currently doing plasma cutting and mig/arch welding on 1mm steel plates for art purposes. The plates are bending a lot so i was wondering what thickness steel plates i need to avoid bending for next time i make an order? The plates double in price if you add an extra millimeter which is the reason i have been using 1mm so far. Thanks in advance

How's it going, I'm going in for a aerospace for tig Welding. Anyone who works in the field of aerospace welding. Could you tell me your day to day? Obviously, it will be a bit different, but is there a common practice? Is there a certain thing common in this field? Is there anything I should look out for? Is this a specific line of work I can get into, as I'm a young welder Just doing stainless tig fab. Is this something go from aerospace to aerospace or a 1 off job? I have a job offer. The offer they gave was studying under there master welder who's been there for a while. My tig fab matched, the employer said. Is it a lot of fab? What Procedures. And what are the common things I might get certified in? Any information will be great.

Been learning TIG for a few days now, I feel like this fillet joint is my best so far other than getting my tungsten stuck at the end

Unsure what every symbol underneath amps and Volts stand for and was thinking this would be the best place to ask?

I own a very small farm in Eastern Canada. I regularly have to weld farm equipment that breaks, but the price of the metal I get from local sellers is exorbitant. Since my equipment is on average 50 years old, the metal I use to repair it absolutely does not need to be new. To your knowledge, is there a way to obtain metal at a better price?

Anybody use one yet? How’s the little light and the electronic screen menu selector thingy? And how’s the auto shade work for you? It seems the lenses are a different size than the old ones????

I have my first competition coming up on thursday and the competition mostly consists of T Joints and one Butt

Hi I was wondering if underwater welding is as dangerous as everyone say? Is it worth it?

I know what I’m trying to do and can do all the steps well. I just can’t seems to get a solid shootable coupon to save my life.

I’m just looking to hear that I’m not alone in fucking this up so many times.

Thank you.

Aluminum pleco tig welding

Any recommendations? I’m talking about 5/6 inch beard if not that then 4 inches

I think I did this one 316L weld good, but I noticed later that rods box includes some 309L rods.. I am 99% sure I didn't use them because they were thinner, but in case I am wrong will I find out after the X-ray?

Looking for a welder that is:

• capable of MIG/TIG out of the box, included gas regulator and tig gun preferred
• can weld aluminum
• will hopefully last and continue to do a sufficiently okay-ish job that I don't feel the constant burning need to upgrade for several years of small intermittent projects
• won't spontaneously burst into flames or electrocute me

I'm all for buy once cry once, but I'm not a welder, and this isn't that to me. I'm a tinkerer, and I just don't have a budget for a real professional welding setup. I'd like to spend under $300 if possible (not including the gas bottle or consumables), or under $500 if it can also function as a plasma cutter (not including compressor). I know there are tons of cheapo welders out there on amazon etc, but I'm not sure what I should look for to get the best value when making compromises for those bottom tier prices. Are there any in that price range with a decent enough reputation?

EDIT: wow, speaking of rolling the dice, I guess nobody on the sub today is interested in being helpful.

Look, I know $300 is too cheap for a good welder. I'm not asking for a good welder. I'm asking what is the bare minimum that can accomplish the job, because I don't have budget to spend on a welder I'm just using to shave yaks.

I searched the sub before I posted. I know everyone is going to recommend $1000+ units. And if I wanted a quality unit and had $1000 to blow on it I'd already have no shortage of good advice to go by. I also know that people on this sub have in some situations in the past said things like "you don't need a good welder, just buy any crap on amazon." What I want to know is, what makes crap on amazon a welder and not a boat anchor with a paint job.

SO let me rephrase: I want to buy the cheapest possible device that can structurally fuse two pieces of metal together. I prefer aluminum for most of my projects so I would like to know what is the cheapest way to do that. I want some level of control above stick welding. I want gas shielding so I don't have to deal with tons of slag. I want to have the option of both TIG and MIG so I have the opportunity to learn both of them and the ability to choose the more appropriate process for different metals and situations. I don't care if its awkward or tedious to use, as long as it does the job... besides, challenging machines are better for learning on IMO anyway because they teach reliance on technique, and if/when I decide I really need something better, I'll have a reason for it and an idea of what I want in a better machine. I also don't mind modding/upgrading machines to fix their shortcomings myself. However since it's my FIRST welder, I don't want to start with one that doesn't work at all, so upgrading is ok, fixing a broken one is not. Not this time.

I would like it all in one machine if possible, to save money and space... but if I need to get separate machines that's fine, it just means the budget per machine is going to be even smaller.

So if you're going to be condescending maybe at least you can start by ELI5 what is needed to stick two pieces of aluminum together and we can go from there.

Acetalyn bottle I was given, can’t open it until I find one that fits. Lowes was a bust.
