I know absolutely nothing about welding. Can I use this to weld replacement footings for a rusted our wrought iron fence railing? Which type of weld works best for iron repair? Doesn't have to be anything fancy just a solid repair.https://a.co/d/5HeueIl
>>2865424You could braze it instead of welding.Most parts rust extra hard at the weld point… even stainless steel… and brazing is made of brass so inherently less rust there.
If you never welded before you would need to practice a bit. Stick welding: Cheapest, you're gonna need some practice for holding the stick and setting amperage. Good thing is you only need the sticks.MIG/MAG is easier, but you'll need gas and regulators and will have to fix the gay ass wire motor from time time. You literary just set the Amperage and press the pistol.And always wear face protection and at least long arm clothes
>>2865437That would be fine. How much does the brazing stuff cost?
>>2865440This model is "gasless" is that just a meme?
>>2865424> Can I use this to weld replacement footingsYes, in general if you are welding dirty ass shit, you'll want to weld with stick (MMA), those are also the cheapest welders. Might want to get more expensive electrodes, some types are much easier to use than others. Will take some learning to get into it.>>2865443This welder can do 3 types of welding, MMA (stick), MIG (pistol with automatic wire feed, easy, fast, needs CO2 or Argon gas for shielding) and TIG (best for fine welds and accurate control, needs CO2 or Argon gas for shielding). I think for the price they are probably lying about the amperage of this welder, it probably only goes to like 80-90 while displaying 140A. I have a similar unit and it does the same thing. It can still weld, just keep in mind that when you read on the Internet that an electrode of specific size needs 90A, it might need 140A on this type of chinkshit welder.
>>2865441Brazing is also the cheapest option.Temperature is only 500 degrees C (for comparison welding… torch welding anyway… is over 2000 deg C).anyway, you just need MAP and O2 tanks, you can get mini ones for around $10. You might be able to do it with propane and O2 as well, and the torch head and other junk. They sell low-end kits.
>>2865424>Can I use this to weld replacement footings for a rusted our wrought iron fence railing?No. Well, not exactly, but it won't be easy. Iron is a pain to weld, and the welds are pretty weak. That's part of why iron has been mostly replaced by steel nowadays.But then again, iron wouldn't "rust out", so chances are you're talking about steel anyways.>Which type of weld works best for iron repair?Stick. Just set the voltage accordingto the stick you're using, hook it up and start.MIG / MAG is a pain to set up, especially on cheaper welders. To much power and it'll burn holes, too little and it won't hold properly. Wire too fast, and it'll punch holes, too little and it won't form a clean weld. Any dirt on the material, and it'll form massive beads of molten steel at the tip of the pistol, which won't connect with the piece until all the dirt has burned off, and will destroy the nozzle if you get the distance even slightly wrong. Also, gas is expensive. Only benefit is that it can weld thin sheet metal, which stick welding can't.WIG / TIG is even worse. Doesn't destroy the nozzles, but you need to be careful so the electrode doesn't touch the molten steel, or you have to regrind it, and keeping up a steady supply of wire with your left hand is hard too learn.Acetylen is pretty nice, and a better alternative too stick welding, but way harder to learn.
>>2865462Odds are OP isn't really dealing with wrought iron as that's nearly out of production since long ago.>> Acetylen is pretty nice, and a better alternative too stick welding, but way harder to learn.Better for what SPECIFIC use case? Not structural or pipe welding. I fucking love gas welding but it's not optimal for everything.Were that actually the general case OA welding would not have been superseded. The path of wisdom is own a torch outfit whatever you do (mechanics especially benefit after they practice washing off stuck nuts etc) plus a small MIG (which can of course run FCAW too so no rush to score oxy and acetylene cylinders which I always buy used).Gas welding, brazing, soldering, torch bending, torch cutting, gouging and more only require a bit of practice (as in hours, not minutes but that's all welding too). Moderns seem to fear torches but not so long ago they were standard in most auto shops and many home gamers have OA sets (which I grab for couch money at their estate sales).
>>2865424wrought iron is the purest iron, easiest to weld, normally for cosmetic welds you can go with 6013 rod, tolerant of rust and fairly easy to use, not the strongest there is
>>2865424Cheap MIG gasless welder should work fine anon. Check FB marketplace see if anyone is selling it for cheaper. If you're just looking to do a quick job without caring about learning to weld just do multiple tack weld the joint all the way around. I wouldnt fuck around with anything that requires gas too much of a headache for a small job.Watch a youtube tutorial about it and you should be set
>>2866232Based. Thank you anon.
