>>3007260The common Victor outfits you mentioned are excellent and the soft parts of their regulators are compatible with both fuel gases. (I collect and rebuild OA gear per factory manuals because torches are like firearms, having subtle but important ergonomic differences.)Victor LP and acetylene regulators differ by output pressure gauge and diaphragm spring so if one buys the acetylene regulator they can use it with a BBQ or other LP jug which has the same internal CGA-510 valve threads. R-rated hoses survive fine but T-rated hoses are technically correct for LP. I only buy used Victor gear (it's repairable in the field for eternity and I prefer the classic SR regulator series) so when I replace old hose I buy T which is a bit less likely to dry out like an old tire sidewall. Uniweld make equal quality Victor style torches (they specialize in making compatible and mixed-feature gas equipment as original patents are LONG expired).
Any tips for passing a weld test for a job? I'm having trouble controlling my heat input on thin gague plate doing t-joints. They dial the amps above 120 and tell me to keep it there, but I can't seem to control the pedal well enough to not burn through the piece.
>>3007492what process?how thin is thin?
>>3007346>noooooooo you cant weld rebar haha 120v 6010 tie wire go brrrrr
>>3008511Lol. Based.
Anyone have experience with Fronius welding machines? I have very recently been placed in charge of the welding sector of a large shop that exclusively uses them for all automated welding processes (TPS 2700 and 320i models specifically). I want to hear anything and everything from anons that have used them i.e. complaints, compliments, common quirks, etc. I feel like I'm constantly fixing one thing or another with them, although that could definitely be due to operator retardation. We have a day shift and a swing shift so I'm not there 24/7 to ensure that people aren't fucking shit up while I'm not looking; it's hard to tell if certain issues are inherent to the design of the 320s or the age of the 2700s.
>>3008765The primary failure that I've come across is the coolant pump failing and most of the time its due to not filling it up regularly. Someone can run the machine dry one day and then realize they've run it dry and top it off and then the next guy comes in and notices the torch is hot and not realize its because the pump isn't working and add more coolant. Then a third guy shows up and the torch handle starts leaking and you send it in for repairs and the mechanic has to fix a broken torch and a machine. If you add some coolant to every machine once a month it should fix all those problems. If you're worried about losing time, the machine are typically designed so you can just open up a spout at the back and pout coolant in while the machine is still running. Also Fronius coolant is literally just water and ethanol, aka vodka..
>>3008770This is extremely helpful, thank you. I've had to go around to multiple machines because they randomly stop mid-weld because of a "No H20" error despite the res being full (I topped off every machine as soon as I took over). Power-cycling fixes it for the day and I cleared all the lines so that tells me that prior to starting this shit they were probably running dry for awhile and the pumps are on borrowed time.
>>3008771Yeah probably coolant refill issue.Don't rely on the operators to top them off, they'll always be too focused on the welding job to think about the machine and since you're working shifts it spreads out the blame since everyone can always blame the other shifts. Paying someone a little bit extra to spend every first monday of the month refilling the machines and get into arguments with the welders will probably save you a huge amount of time and money. Narrows down the list of suspects a lot if you keep having the issue.
How popular is it in the United States?
>>3009681i have 3 rogues and 3 firepower branded machines plus 2 old thermal arc inverters that i guess count plus a tweco branded lorch thats now sold as a warrior 300im pretty happy with most except the lorch because of its faggy ass safety features and it was all far cheaper than big blue although my old xmt gets more hours than all the rest combined i have a love/hate relationship with esab wire. their dual shield runs beautifully right out of the box smoother than lincoln or triple7 but picks up moisture and worm tracks in a day sitting in the feeder if the humidity is even slightly up
I scored a couple 6-ax robots with controllers at auction. Anyone know the most /diy/ way to get them to become tig welding robots? All I want to do is weld around circular objects like pipes and flanges
>>3009720https://www.youtube.com/@Swarvar/videosno robot needed
>>3009720can i have one
Rate my weld. It was my first time. Nobody ever taught me. It failed on the first load (1 ton)
>>3010455
>>3010455What the fuck am I even looking at?
Any of you shop faggots have any advice on how to dial in mig? All I have ever really done is stick with the occasional fucking around with innersheild whenever I get the chance. Im an actual man who works in the field, not the gay fabshop.
I made this at work out of 2 inch flat bar a bit ago when I was bored.
I have a weld test later. Ill need to do a vertical fillet with a root and cap.Send help.
>>3010766Just don't forget to give your coupon plenty of time to cool off. Last thing you want is for it to warp or crack.
How do I make good jigs? I'm new to this and just sold my first item I made. It's really difficult welding it up though, I'd say half the time is spent aligning the pieces together and tacking so is there a secret to fabbing a good jig?maybe I should just stop being a fucking chud and use my milling machine I got at an auction to drill perfectly spaced holes then make a mini fixture table.
>>3011166Depends on exactly what you are making the jig for. If it's something you plan on cranking out 100's or 1000's of then a dedicated jig for that one item is the way to go.
>>3011192Yeah, I want to crank out 100's of these things, making them is real simple too but hopefully a jig will make my 2 hours of welding and struggling to get shit aligned turn into 3 minutes on the welder and 3 minutes prepping them up.Think I'm going to straight up weld C-clamps to a plate and ghetto rig the shit out of this thing.
>>3011221de sta co clampsbetter to have pads to create the support plane with openings for corners and weld points to keep shit from getting under that throwing position offthats all the free design info im gonna give
>>3011227Oh I have these too, thanks I'll dig them up and get to working on a fixture.
>>3007502Using a petal sounds like TIGyou might wanna try clamping a few brass bars to your work as a heat sink, also dont be such a lead foot
>>3011315How hard is tig? I have only ever done stick and a little mig. Is it just pushing puddles around, just like everything else?
>>3011318The best way to l;earn TIG is to learn gas welding first its a similar process, you have a rod in one hand and a gas or TIG torch in the other, your moving the puddle with one hand and dipping the rod in with the other.Its easier to understand when you see it done.
>>3011320So it's basically brazing. That doesn't seem too difficult once you get a feel for speed and temperature. What does the pedal do?
>>3011322The TIG peddle adjust the amps/heatYou set your welder first and and with the peddle you can fine tune your amps, sometimes the peddles can be a bit touchy
You can weld almost anything with TIG mild steel stainless steel aluminum, I even made a small bag out of dimes once
>>3011409Can't weld anything big or structural. Real men use stick or an LN-25 with inner shield.
>>3011461Tell that to my Great Aunt Rosie
>>3011496Her name isn't Rosie the welder, retard.
>>3011496That isn't even Rosie the riveter. This is. Your image is based on a moral poster that was only displayed inside Westinghouse facilities. She wasn't named Rosie and didn't even have a rivet gun in the image.
>>3011513I remember some of the macho welders, too macho to wear leathers, welded in short sleeves cuz it was hot outside , ended up getting the equivalent of a REAL bad sunburn from the ark.welding is a dangerous profession safety always comes first, take pride the quality of you work not the unnecessary risk you take safety is cheaper then law suits and health problems Mr macho pride does not buy groceries
>>3011528What's that got to do with throwing rivets? It's not welding.
>>3011595joining pieces of structural steel together both have advantages and disadvantages
>>3010479Your machine should have specifications listed on the inside of the hood or in the manual. It will say what settings you need for what thickness. Set it to that then adjust to your own preferences if it doesn’t feel right. Also just fucking google “X thickness in Y position with Z welder Settings”
>>3011318TIG isn't hard but there's basically an infinite skill ceiling, especially if you care about aesthetics. I've probably spent 13 years TIG welding and there's always more techniques that I can learn to get nicer looking results.
Is there something I can use in my torch cooler that will actually stop rust? I am tempted to use automatic transmisison fluid this time around.
>>3011909wtf are you using now? ive had cantesco coolant in a homemade cooler for years without any maintenance and its still fine
>>3011909yeah, pure ethanolhttps://www.laballey.com/products/ethyl-alcohol-pure-200-proof-undenatured-acs-usp-grade
>>3011926>flash point 49°>readily absorbs water>torch coolant lollmfao even at least its kosher and halal
>>3011925Organic acid engine coolant, the kind with no silicates or phosphates. I was using an old fuel pump and it corroded the steel shell of it and the rust particles clogged the pump.>>3011926Seems a bit flammable for the task
I have been looking for an excuse to buy a welder for years but I don't have any real use case that justifies the purchase, so help me out:I heard you can jumpstart/charge a battery with a welding machine but i also see a lot of "it's dangerous" and "not true you'll blow it up""Dangerous" is fine in my book as long as it's actually a doable thing I'm about to buy an analog trickle charger without all the safety mumbo jumbo so i can desulfate completely dead batteries and it's goign to cost me ~130, looking on FB marketplace and in pawn shops i could buy a welding machine for that much...if i can charge / desulfate batteries with a welder ill buy one since it'll make more sense to have a welder AND a battery charger vs just a battery chargerCall me retarded or tell me this is a good excuse to get a welder, ty
>>3011960A welding machine is for welding. If you want to jump and charge batteries, buy a battery charger.
>>3012047>welding machine is for weldingits my power supply and ill do with it whatever the fuck i wantjust put 20 hrs on my electric over hydraulic manlift bucket truck trimming trees using a 400a multi process inverter lorch welder to run the 12v system instead of buying 6 batteries because ima cheapfuck hillbilly set it to 13v/0 impedance constant voltage for wire welding and let er eathad a stone dead old core battery in series to keep the open circuit voltage down and it got to boiling pretty good and actually revived it enough to run the hyd pump for a few minutes on its own after a couple hour sessions of tree work on the welder
somebody take a fucking video of what a 4x miller looks like when striking an archow the hell is there not a single one on the internet yet
>>3012381Just get a Vulcan from harbor freight for like $150
Any resource to advise on best method/settings for specific tasks? Seems like the kind of stuff an app would be perfectly fit for Picunrel
>>3007346Hey, how is your health after welding for few years? I was thinking of doing a course and maybe finding some job since i live in shithole nowhere, my chemistry degree is useless anyway, there is like one lab hiring but they pay less than a cashier.
>>3012792It depends on what you are welding and for how long. Hex chromium is no joke.If i know that i am going to be welding hard face, in a poorly ventilated space, or for more than like 30min, i use my PAPR hood.
>>3012792It's fine if you use proper PPE and ventilation. I'd never do any welding professionally if it didn't have something like pic related. Obviously long term effects are an issue but we're talking shit that'll show up in your 60s and 70s. If you're switching careers from a white collar work you'll just figure out how to get out of welding as well, it's not a job people stay in. Figure out how to operate CNC machines, do CAD work, manage logistics and general office work for the shop. There's loads of options to get you out of welding.
>>3012781Nvm, just found a bunch online
