Anybody have any experience with these?

My supplier has got them on discount from €240 to €140 so im thinking of getting them. I used to have the huawei freebuds pro2 they lasted me a whopping 4 years. Airpods barely last a couple months. Im thinking of trying these out. They are rated as dust resistant so on paper they are pretty compelling.

I need some questions answered about joining a union

I’ve been welding in shops for about 10 years. I’m not certified, but it’s at the point where I’m needing a lot more money than I’ve been making in shops. I’ve mostly done mig welding, but I have done some stick. Would I need to get certified before joining or with the experience that I have, could I find a union and join and get to work? I appreciate all feedback. Thanks

I think ima need a new career

I’ve been fabricating for a couple years. But I think ima need to go back to school and use my head a bit more than my hands. When I was in hs I originally wanted to go for robotic engineering. I have background in cad, machining, tig, mig solid and dual shield. I preferred not to get a career behind a desk but I think it’s my best option going forward. What higher education or careers have yall pursued after welding/fab?

Buying a tig welder for a friend

Hey r/welding, I am looking to buy a TIG welder for a friend. This person has some experience welding and need a welder that can do 1/4" aluminum. Afraid he doesn't speak English so shopping for one is a nightmare and I have no experience in welding.

From what I have seen so far from this sub: torch has to be at least 250 amp for welding aluminum, the higher the better. We are living in Canada so we have access to 120v outlets. We are also looking for an aluminum spooler as he is used to have one before. We are hoping to grab one under 1k CAD and we can it from US if we need to.

What are your recommendations? Would we need any other supplies to use it?

How to get into pipe welding

I’m going to be moving states soon, I would love to get my foot in the door welding pipe. I’ve got almost 10 years of welding/fab experience with aluminum, stainless & carbon in both tig and mig with about 3 years of stick experience. So what’s the best way to get into a place where I don’t have experience in the specific field where they’re only hiring welders with pipe experience? I know union is an easy answer but I would prefer to work for a good company over union. Should I do a pipe course at a tech school even though I am very comfortable welding? I currently hold 6 certs at my current job doing heavy structural.

Wire size - what happens if it’s too small?

110v CO2/argon MIG. Hobbyist.

Got a recommendation on here to run 025 instead of 035 (I figured bigger is better) on thinner stuff (mostly around 16g tube).

I’ve noticed everything seems much more controlled with the smaller wire.

Question is, what happens if I try to weld #3 rebar to my piece? Usually just making doodads to use around the house (firewood holders, etc) so nothing structural. Do I just get less penetration/poor fusion?

Beginner in St Louis

When I say beginner I mean...GREEN. I have a 110 and a 220. 110bis an old Craftsman 100AC infinite Amp Arc Welder. The 220 is a Chicago Electric 225 amp arc welder. Couldn't wait to try my 225! Ground an od bedframe bare to get a good ground. Laid flat. Plugged it in cranked it to 160 output amperage. Grabbed a 6013 ....got down to metal. Sticking everywhere....my weld was not pretty...to embarrassed to show here. My question. #1 Can somebody explain the difference of what 60 amps does versus 225 amps. #2 what is a common item to use as practice metal. #3. What rod would you recommend for being a beginner!

There’s a shaded part on both sides of the dark area. Is this going to cause me problems? I’ve never seen a helmet like this.

Is there a list of all CWB tickets anywhere?

So on the 10th I'm doing my SMAW flat ticket, which I am both excited and nervous for because of the xray (stupid spatter balls). However thats besides the point....I've tried looking up a list of all the tickets the CWB tests for out of curiosity, but couldnt find anything. So is there a list anywhere of all of the tickets you can get, and if so does anyone have it?

Thanks!

Consumables / tools / accessories for a new TIG welder?

I just ordered a PrimeWeld TIG225X for my home shop after falling in love with TIG in my buddy's garage. I know I'll need argon, electrodes, filler rod, wire brushes, and other odds and ends - I have a good helmet, gloves, etc. already. What else should I consider? The welder itself comes with a CK torch and a pedal, so I think I will be okay there for now.

I'll probably do mild steel at 16 ga. to 1/8 for now, possibly branching out to stainless in the same weights somewhat soon. I don't have solid plans for aluminum, but I'd guess I will get there eventually.

Getting started at a hobby/minor DIY level - where to weld?

Not sure if this fits the best flair - there's loads of reviews and advice on equipment but I don't see a lot of "where" to weld.

My use would be mostly light DIY and hobby level stuff - like grinding off and fixing a cracked weld on cheap purchased stuff (e.g. 300lb limit hitch tray, mulch guard on mower deck, folding table/chair, light duty wire shelving with broken welds, etc) - I've had SO much stuff I have had to throw away because

The 2 most obvious places (to me) would be in my 2-car garage (maybe move the gas cans out of the area first) on the cement floor or in the driveway outside the garage. That would also put me close to where I can plug into a 50A 240V power source (14-50 non-GFCI non-AFCI outlets that were installed by an electrician for future EV charging, easily adapted to 6-50 for welding).

How far away from stuff should I make sure to be so slag doesn't fly and damage anything (even cosmetically)? Will the slag stain or damage the cement floor of the garage? Drywall proximity to not set the house on fire? Should I put down a welding fire blanket to work on covering the floor?

To a similar end, I assume a standard ABC type fire extinguisher would be the most appropriate thing to have nearby in case something does catch fire?

I'm probably being paranoid, but I would prefer to err on the side of assuming its a problem until I learn otherwise with the safety aspect.

Would this be safe to go 130mph+ after getting it welded?

I don’t think it’s that bad of a crack so I feel like getting it welded right could get it right back to normal but I’m not a professional.

Going from a 10-15ft welding lead to 30ft? What do I need to know?

Hi all, I would like to be able to leave my welder stationary and get a longer welding cable/ground and work all over my shop without having to drag my welder around. My welder is a Primeweld MIG 285 with I believe a 10ft welding lead (it might be 15, I have not measured). I would like to upgrade it to 30ft. My question is, what do I need to know about doing this? Will I have to change the settings in the machine? Can welding machines even support longer leads? Im assuming it'll be harder on the gears inside the machine because it will have to push that much more wire, is there anything I need to do to mitigate that? Im not an expert welder by any means and any advice is welcome

Miller 251, worth fixing?

So my buddy got an old Miller 251 that was broken and I am wondering if it is worth putting the money into it to fix it up. It is throwing a code for circuit board bad. If it is worth fixing where could I send the board for repair or find a replacement? I am in Canada BTW. I can't visually see anything burnt on the board or anything.

Amateur welder with a dumb question.

Hey everyone! College student here about a semester away from getting his associates in Welding Technology. Absolutely having a blast and this isn’t a field I would have ever thought would be for me but I seriously can’t wait to graduate and start running beads as an actual source of income. Until then, I’m pretty much limited to the shop time they provide us, which is one day a week 8-5. I’m looking for a small welder of my own to do little side projects and throw things together that I might need around the house(tables, shelves, monitor stands, etc.

I’ve been looking at this Lincoln Weld Pak 90i FC for something easy that doesn’t require me to pick up gas bottles. It also uses 110-120v input which is perfect for me. I live in a townhouse style apartment and my back porch has two traditional outlets.

I’m well aware this is an extremely low-power welder, I’m not looking to throw together a building or anything, just want to run beads for fun. I’m just unsure if my apartment’s breaker could even handle it. I’m 95% sure those outlets run on a 15A breaker which is shared with everything in my living room. The only other option for dedicated power inputs would be a 20A 120v for my refrigerator, and a 60A 240v dryer connection. Both of these would be highly impractical to move just to run a project.

Basically my question is this, is a 15a circuit adequate for this machine? I’m not looking to spend 300 dollars for a fancy breaker tripper that I can’t use. And I can’t really find any definitive answer online regarding its input requirements other than the 110v plug. Figured I’d ask actual industry professionals for advice, and much thanks in advance.

5s has ruined manufacturing

Does anyone else think 5s and similar things have ruined manufacturing was it different back in the day iv only been in for about 8 years but it seems most places prioritize pointless cleaning over production
