Re: Tested onboard welder. Pictures.
Cool, I like your design, kutyafal. I am looking for a welder for my shop and I have never welded. I don't expect to weld on my Jeep very often but since I have a small garage I don't have much space and it would cost me almost as much just to run 220 out the the garage as it would to make my own onboard system. I have two options for driving the welder- I have an extra pulley on my crank that used to be for A/C or something, and I have PTO. I run my winch off the PTO but it has a clutch on it so it would be simple to mount the alt on the bumper and run a belt over from the winch drive. That way the alternator would be out in ambient air and would be cooled better.. But, it would be more likely to attract thieves and there is plenty of room under the hood so I could mount it right to the engine. I'm trying to decide... A very cool winter project this would be.
I have been thinking of installing a cheap cruise control and mounting the sensor to the PTO shaft instead of the driveshaft and using it as a governer/voltage regulator. This would be cool. The pto shaft still spins at the speed of the input shaft the the transfer case so the cruise could be used in low range off-road and not drop out due to low speed. I could still use this method even if I just mounted the alternator on the engine. I could rig up a remote so I could speed up or slow down the engine from the gun and also cutout/resume while I am not welding. I would also rig up an ignition cutout to a deadman's switch for safety.
