My Hybrid welder works (a Mig welder running off of 24v)
Ill work up a write up after I get back from my current trip on the dusy. Here are some pictures of the welds that I did. Its bascially what a ready welder is but without the price tag. My cost (not including the old welder) was just about $35 in parts, the rest I had laying around. Below is the list of what you would need if you were to start from scratch.
1. Harbor freight 90 amp welder This was my first welder, but it had outlived its usefulness as I got a better machine. Frequently on sale for $90
2. PWM (Pulse Width Modulation) motor speed control ($25)
3. Jumper Cables ($15)
4. Plastic Home Depot tool Box ($8)
5. Battery Disconnect Switch ($4)
24v .030 flux core wire
Also did some with 24v and .035 flux core wire but no pics of that, It seemed to transfer the heat even better into the metal.
The Top Picture is 100% off of the battery welder, with no wirebrush
The Second picutre, only the 2 horizontal welds are from the welder, wirebrushed just to get the brown stuff off. Looks like I am getting good penetration from the welder. It welds much better than the 90a harbor freight special ever did.
Now here is to hoping I will never need the thing
