Vulcan omnipro 220 welder guy from the last thread... Welding cart from filing cabinet has been fully fabricated, just need to find the time to properly paint the file cabinet orange and assemble the final time. Also ended up with another identical Vulcan omnipro 220 that popped up for sale locally barely used for $600. So now I will have to make yet another welding cart...

Building a truck camper and I plan to do MIG Aluminum. I've never welded before in my life and I honestly have no idea how it works. The extent of my understanding is "big, hot torch melts metal to other metal"How much should I spend on a basic beginner set up? How in over my head am I?

If I get a cheap Tig welder from Amazon how long would I need to practice to make some basic aluminium or stainless parts like a light fixture, maybe simple gps mounting bracket or a skid plate? It looks like a fun thing to learn but I’ll be doing it maybe 5-6 times a year for practical stuff so I don’t want to spend a thousand if that’s possible

piggy backing off the omnipro 220 guy. I need a spool gun to repair my outboard but Ive yet to pull the trigger(pun intended) on the vulcan brand one at HB that like 250. Is there a cheaper alternative on amazon? I actually have so much time Ive thought about trying to 3d print one

I've been welding for about a year, and my company has a few positions open for inspection (they train you) and I think I have a decent chance. I was planning on going to inspection eventually anyways. Can't decide if I want to jump the shark and try for it before I'm all that good at welding or stay the course. Should be up for tig training soon but inspection would be a big pay bump.

Last thread I talked about my old century welder that shit the bed and that is why I picked up the Vulcan from HF. Anyways one of you guys mentioned it was probably a bad diode. Finally had some time to tear into it again and looks like you were right. Ordered some new diodes and should be able to get er up and running again for cheap.

Not a welder just visiting this thread. I have some very basic stainless stuff I want to weld together. I plan to get sheets (2mm) laser cut and just need to weld the some inside 90 deg corners. I did SMAW classes in school but it’s been 12 years and wasn’t stainless. Only thing I want to ask is if I get a smaw welder and practice for a few weeks is it achievable or should I go and find a welder guy? Hobby project, it is basically very big storage boxes, does not need millimetre precision

Yeah, I used lots of water.The thing is, I live in fucking Argentina and there's no way im getting a refund or warranty.The base is cataloged as a "Stainless Steel Clad Base" and the Pressure canner is made out of aluminum.I want to weld it back together (Dont know shit about this subject), but I dont know if its a good idea or I'll end up doing cosplay of a drone strike zone.Toughts?

I'm trying to weld two tubes together, butt to butt with one overlapping part of the other like pic rel, and one is made out of 4140 and the other is mild steel due to it being the only material available in the specific size
I have 0 experience welding but I know somebody who does (but their welder no longer works so I need to buy a new one)
what I understand is that I have to heat up the 4140 section (I have a gas forge or a propane torch available to use, am open to rigging something up if the soot would be an issue)
and it can't warp or anything, I'm hoping it wont be an issue anyways since the mild steel tube is 3mm thick and the 4140 tube is significantly thicker but i can never be too safe
>just hire somebody to do it
it's for a gun receiver, not illegal to do myself or with a friend, I just can't pay somebody to do it for me
if its impossible to do with the mild steel tube just tell me, but it would mean a loss of $240 worth of machined metal

Can anyone explain me what the fuck is going on?
I am trying to stick weld EMT conduit, 3/4 or 20 mm idk, thin wall, 1.1 - 1.25 mm at most
6011, a mean bastard of a rod that burns hole in 4 mm steel like nothing, I was able to tack weld this shit.
6013, glorified solder rod, kept burning holes, no matter what amerage I try, not to mention that slag was really annoying to deal with.Neither is good weld but with 6011 at least I got something remotely looking like a weld. 6013 I got slag and holes.
Fucking why? What am I doing wrong?All rods are 3/32 and all are tack welds, because well, u can't run continuous bead on this thin of a metal

Starting a trade program at my local community college in a week, main focus is welding but it includes some manual machining and other fab-related stuff. I used to work at a race shop that built rollcages, did chassis repair/reinforcement, etc. so I've been around MIG and TIG welding and assisted a bunch, but I've never actually run a torch. Any suggestions/advice, or stuff I'm probably gonna want that won't be supplied by the school/will be inadequate? Sounds like PPE is on us, already planning on buying once and crying once with a decent helmet and gloves but not sure what else I'm gonna want.

Howdy and apologies, this isn't exactly a welding question but I didn't want to create a new thread for this and this seemed like it might have been the best spot.I have a bunch of galvanized steel circular punch outs from your standard electrical boxes and I wanted to turn them custom coins for personal use by etching a design into them. An engraving tool didn't quite work so I suggested chemical engraving. I've tried both white vinegar and metiaric acid solutions with a 9volt setup but neither manage to get actual depth, just discoloration in the pattern I've put down.Is there a better chemical to use, or should I get a car battery to up the voltage?Alternatively: what's the feasibility (and if feasible best method) to melt them down to pour? I've seen a sand\clay mold method I think I can replicate if I can get the metal molten.

Practicing for flat stainless flux but I don’t understand the heat thing.
I’ve heard two berry different things. One is that the stainless turning dark purple causes it to go brittle and it will just crumble during a bend test. The other is that the only thing heat does to stainless is cause the chromium to oxidize which will mean it looses its corrosion resistance, but won’t affect destructive testing

Hey everyone, there's a good chance I'll get hired at a salt factory and they asked me if I know how to oxy weld so I said yeah on a bluff. I tig everything all time, sometimes use smaw but never worked with oxy acetylene torches but heard it's similar. How hard is it gonna be to pick up and how do I bullshit my way through it so they don't find out I don't know shit?

First welds either. Machine was set up wrong on the first few passes (was in remote setting mode and ignoring the settings on the machine itself even though the remote wasn't even hooked up) and obviously got a hell of a lot easier after that was fixed.

How do I go about getting the smallest possible weld on a relatively thick metal (6mm or 1/4" in freedom units)? Stick or MIG? Thinner or thicker rod/wire? Crank more amps or just enough to actually fuse things?

Aside from the obvious hole (slag inclusion?), how's this looking for my second day of welding ever? 6013 on mild steel. I stupidly only took pics of 3 sides and missed the best side.

Class #3 of welding, 7018 this time. Had a really hard time starting it without sticking (stupidly I often get it going but then come back in too close too fast and get really stuck) but otherwise pretty easy to weld. Pretty much every blob on there was because I ran out of room for my knuckles when the rods got short and had to shift around. IRL I'd probably just stop with like 3" of rod left but the instructor busted our balls about using the whole rods down to the numbers.

I am trying to get the most out of a tiny 3-1 Chineseium welder. I was told to swap the polarity for better gasless MIG results, but the negative terminal uses a solid aluminum bar screwed down to another large component inside the welder, instead of a thick stranded copper wire, like what was used on the positive side.
Would it be fine to swap the aluminum bar with a thick gauge copper wire?

There's an overwhelming amount of information out there.Thinking about zink/hydrochloric acid/ammonia to make a catalyst then using hydrogen peroxide as an instant agent.

Can a common stick like 6013 be used for (airless) arc gouging? I mean you can blow holes with it if you crank enough amps, but can you use it for a more precise work that way? Fucked up and welded shit wrong and now have to remove a few stitch welds in a tight corner where the angle grinder doesn't reach. Will it work or will I just end up shitting more metal on top of original weld? I know there are special electrodes for that but I have to make do with what I have.
