Like muffler fluid, the battery powered welder has gone from a joke to reality recently.
Not a plasma cutter, but same power class, and certainly able to heat a padlock shank to melting. https://www.dewalt.com/product/0447800880/esab-renegade-volt...
Damn, didn't know that existed but it makes sense with how much power lithium ion can deliver.
I'll have to keep my eye out for the Home Depot buy a battery and get a free tool deal on those.
Heh, I'll have to watch for that sale.
4x12AH batteries, that's gonna be over $1200.
I doubt you could charge them faster than the welder can run them down, so you might want three sets and two gang chargers if you want production anything like a plug-in machine.
Matt's Off Road Recovery uses one to stick broken Humvee steering rods back together about once every four or five episodes.
But people have been welding with batteries for ages. The most primitive welder is a car battery and a couple of wire leads. Tons of videos of it on YouTube.
Yeah, fair enough. Two car batteries in series is even better. Not easy on the batteries, but it will get the jeep out of the bush.
You can also make your own stick electrodes from coathanger wire tightly wrapped in paper.
I couldn't tell you how many pairs of sunglasses you should parallel to protect yourself...
This rig, on the other hand, is something you could pack into just about any plant and fix something with without raising any eyebrows. If you have $5,000 to spend, that is. Super handy for small jobs in hard to access places.
Hearing about it did ruin the "cordless welder" jokes my coworkers used to share.
Reminds me how the Sinclair C5 failed because the inventor couldn't source a 15 mile long power lead.
Shouldn't the sunglasses be in series?
Batteries in series, typical stick welding voltage is ~27v. You might be able to light up on one battery, but you will quickly learn why it's called "stick" welding.
I wouldn't arc weld with any number of pairs of sunglasses, that was firmly tongue-in-cheek; but yes you are right, stacked glasses would be series.
Also, if you try this, before pulling the battery from the non-broken jeep, drive it to the top of a hill so you can bump start it later when the battery is too dead to turn the engine over.
