Arc welding off dual batteries...really?

Yes you can, I've done it with thin rods and a little arc thingy that was bought for welding car bodies with a stick.:)

How long can your batteries sustain one of those?

. How long of welding duration time will I get out of a pair of batteries before I will need to recharge them?

Answer: Many factors will determine the length of acceptable quality welding duration time, with the primary factors being the type and size of batteries used and the type of welding being performed. The thicker the metal being welded the greater the amperage draw will need to be to obtain satisfactory results, which will drain the batteries faster. The size and amp hour ratings of the batteries used will determine the total amount of power available and thus the welding time available. We typically recommend group 31 marine deep cycle batteries as a power source for the Ready Welder II. A fully charged pair of these batteries will normally yield a minimum duration of about 45 minutes when welding 1/2″ steel or 3/4″ aluminum @ 175 amps, while lighter duty welding operations on thinner metal can offer a duration time of 4 hours or more. Please see the operating guidelines page for more battery discussion.
 
I've seen that done many times in Africa but never had a go myself. I can weld reasonably with a MIG (in my opinion anyway) but never got on with stick welding for some reason. One day I'd like to learn TIG welding as it seems much cleaner.

Best to use a invertor to bump up the voltage, the rods stick to the matal like **** to blanket on low powered welders

Don't they just!!


I take it the motor would have to be switched off, otherwise you risk surge and fecking the few leccy items defenders have?
