A Field Expedient Welder, Only MacGyver Could Love.

If you needed to weld something in a pinch, what’s the minimum complement of equipment you could get away with? In [Professor Bardal’s] case, it’s a couple of motorcycle batteries and a roll of flux-core wire, and not much else.

I suspect this one is going to elicit quite a few comments, not least by the welding fans who no doubt will be triggered by just about everything in the video, especially by characterizing this as MIG welding [it’s FCAW or flux-core arc welding].

But it bears some superficial similarities to MIG, at least insofar as there’s a consumable wire electrode through which a high-current DC supply flows, creating enough heat to melt it and the base metal.

In this case, the current is provided by a pair of 12-volt motorcycle batteries hooked together in series. There’s also a torch of sorts — a short length of copper capillary tubing with a 1-mm inside diameter clamped in the jaws of a stick welder stinger, or a pair of locking pliers if you’re really in a pinch. The torch is connected to the negative terminal on the battery with a jumper cable, and the positive terminal is connected to the workpiece.

To create the weld, a piece of 0.8-mm flux-core welding wire is threaded through the capillary and into the joint, and fed by hand as it’s consumed. It’s awkward and awful, but it works. Of course, there’s no control over amperage as there would be with a legit welding machine, which would make it hard to adapt this method to different materials. Weld quality appears poor, too. But I suspect that if you were in a position to need a welder like this, you wouldn’t really care about any of that.

Point and squirt welders are at Lidl UK again £69.99.

Really simple gasless MIG welder. A good way to get into simple craft welding.

Average work day full of fixing other peoples’ mistakes 🙃

Just thought I would show the first weld I ever did and photographed back in 2021. It was probably a week of two into my welding program give or take.

2F stick weld with 6010 on mild steel

I’m a welder and just started my A level schooling which is sort of the top level of education in welding where I’m from. This is one of my first welds in the course. Its not beautiful, but we’re getting there 🧑‍🏭

Oh, and for anyone who cares, this is a 2G tig weld on mild steel

One dump run, three slash* runs for myself, one slash run for my neighbor, and I brought over the welder and fixed a dangerous railing after that. Sadly I didn't get a "before" shot of the railing, but it was barely holding together and would have collapsed under any weight (lots of sharp edges too). Not my cleanest work, but it's very sturdy at least.

After all that, I'm pooped. Just barely managed to beat the rain too!

*slash is a term (maybe just local?) for branches removed/fallen from trees. It's a fire hazard and we have strict rules about cleaning it up.

A 1994 Dodge Dakota, shot from the back with the tailgate down. The bed contains a welder, some hand tools and protective gear, and a tank of welding gas (don't worry, it was fully strapped in before I left). In the background, a garage is partially visible to the left, and trees take up most of the area in front of the truck.

A metal railing and staircase. The railing has been recently rewelded and painted with fresh black paint. In the background are some scattered pine trees and an open field (septic field). A section of fence and part of the garage building are visible.

What are you going to chip with this chipping #hammer that came with the #welder??? #Ants? Is it just #notional?

I love the word notional. In design reviews when people look at you funny or you get a bad vibe just follow up with "but ofcourse the design is just notional for now!"... ahhh! Yeah! I get it!

Got the battery box problem sorted out, tacked it to the frame then removed the wheels and hard welded the battery box frame and other elements that I had tack welded previously. After that I cleaned up the welds and I then made a grain-free but gluten-full pizza for the crew's lunch.

A great day of fabrication and welding!

We made the mounts for the wheels and got the componets tack welded to the frame and itself. We also made the mounting points for the shocks from angle iron. #fabrication #fabricating #fabricator #welding #welder

Live action CGI of me welding. And, yes, I do my own stunts.

Me in the background with torch in hand, Steve is the cyclops AND the brains behind the build itself. I am only the hands with the occasional good idea.

I really like the tacks that I did on these corner pieces. The layout is very attractive. And they just pop when wire brushed.

Did some practice welding before getting to welding the face joints on the frame. Started by tacking the angle iron to the frame to help stabilize the joints while they are welded. Mitigates the movement of the metal from the heat. Then I tacked the 1" tubing and then did beads all around on both faces. Capped the ends of the long 1x2 with flat bar. Followed up by grinding the welds flush to the tubing. #welding #welder #fabrication #fabricator #beetlebike

Found this in an abandoned cabin in the woods near my house. The piece that allowed the candle holder to mount to the bracket was broken off. My friend ground down the threads on the hex bolt and I tack welded it to the candle holder. Needs fine tuning to level it out but it will do just fine.
