adjustable AMP car battery charger+ carbon rod= welder? Answered

Is this a good idea?  It goes up to 200 amps. Thanks in advance for your answers


What kind of car battery charger gives you 200A?
You should use welding rods, and like steve' said without regulation you've little control over what it does.


Its a charger/engine starter with 2, 10, 40, or 200 amps

Ah, a starter too. I'm thinking that it wouldn't give you 200A for long. That is you'd spend a lot of time waiting for it to cool down.


Yep. Look at the manual for what its rated duty cycle is at that power level.

Small I should think<5%?
(for some reason I didn't want to mention "duty-cycle").


thank you all for your input

Why bother with the carbon rod ? It will weld (DC) directly. Not sure how well it will work, because the regulation is usually non-existent. Try it.
