Default Building a welder

Seems like this is a fabrication type project. Being the poor broke individual that i am I figured I would have a go at building my own welder. Found a few good links in the net so the research has begun.

Just figured I would tap the brain power of GL4x4 and see if anyone has ever done such a project.

In the research I have done it appears that microwave transformers are the way to go.

seems to me that by the time you buy/scavenge components together to have a functioning welder, you would have as much money and time into it as you would to buy a decent used welder, with better settings and easily replaceable parts.

but if you do decide to build your own, good luck and dont electrocute yourself. id be interested to see what you come up with. subscribed.

I'm just looking into a simple stick/arc welder.

I am also researching a used machine also weighing the cost.

The building of the welder is more of a "lets see if I can do it" sort of project.

I'll post more as I figure out the parts.

I'd imagine even a harbor freight welder would perform better then what you could build and also be cheaper.

if you want to build this to actually use it, then save your money and buy one

if you want to build it because you enjoy building things like this and want to see if you can build a functioning welder, then have fun and post pics


seems to me you can also do this with a modified alternator and a small gas engine...I seem to remember a popular science article on it, or something along those lines.

you can buy a Lincoln Buzz Box for less than $100 in most cases, but building would be cool if you were into that sort of thing.

Unfortunatly I haven't been able to do much more research on the home built welder, but i did come across something else the caught my eye (yes I probably am add. HA HA)

Gas welding. The set up is super cheap and you don't need electricty. Very mobile. Whated a guy do some fencing this weekend, makes great welds. I understand this may not be the way to go when stickin thicker material together, but for the small stuff I want to do this is perfect.

Just buy one off craigslist and spend your time learning how to use it.

I'm no expert welder, but I can fumble my way through it. Owned a millermatic 140 for a few years. loved it. Built about 20 bbq pits with it.

Again I'm not a master but I can get by.

Just because I am curious about the gas welding, anyone recommend a good outfit? Harbor frieght has one for about 180 bucks (not including tanks of course).

When buying one of these what are the important features. I understand the concept, set pressure from tanks, wet flow at torch tip, weld away. What makes one set up better then the next?

Gas welding is fine, plus you will be able to braze body panels and other thin material with it. I would imagine that just like everything else the cheaper the price the lower the quality of the regulators, handles and tips. Plus with gas welders there are different stlyes of handles so a cheap one probably wouldn't have the same mounting style as one from a good set. That being said i learned on one from Harbor Freight and it did fine, but for the cost you can get a cheap 110 volt wire feed that will be easiert to set up and use.

Also, the micro wave parts for a welder are used for the high frequency needed for tig welding, not a buzz box. Make yourself a lead jock if you go that route!

if your going to try and build your own just hook up 2 or 3 battries together with a couple jumper cables and there ya go, a stick welder.

I have my eye on the harrbor freight one. Will this set up take better quality parts if i chose to upgrade down the road?

Newb question. What exactly is a lead jock?

price the gas bottles you may get sticker shock!!! A arch welder will be cheaper in the long run. If it comes with those little bottle 20cf? they only last about 30 minutes.

It's what you's want to wear if your homemade microwave welder is not sheilded electrically. Unless you like your nuts roasted!

Seriously though, if you want to experiment, sign up for a welding class at your local community college. I took a couple here in Muskegon and they are cheap and you'll get to try gas, stick, MIG, and TIG.

Myself, I'd go with the stick first, you can weld thin to very thick with one, they just take a little more practice than a MIG. If your dead set on building one, try mounting an old Ford alternator (it must be the stle with a seperate regulator) on your rig, you'll find lots of write ups about it. That way you've built your own welder and it's already on board your rig.
