one of my neighbors thought he had a really great idea, he has a car trailer and a nice miller 140 amp welder, and a DC current to AC current converter that he used to power a lap top computer.
his plan was to plug the converter into his cigarette lighter like he always does with his lap top computer that runs on 110 volts AC
plug an extension cord, into the converter and the 140 amp welder into the extension cord.........

and for some reason he failed to grasp the potential problem.
running a welder off a cars cigarette lighter power taps, a bit like expecting to put out a house fire with a typical drinking fountain filling dixie cups used in a bucket brigade!

we all learn to work with the tools we own and eventually, I think. most of us come too think of the tools faults or virtues as the way EVERYONE DOES IT.
Ive used those 140 amp welders and was actually rather impressed and well pleased with the results..well UNTIL THAT WAS UNTIL I used a buddys MILLER 252 mig, and a friends LINCOLN 300 amp TIG welder , I think its a case of not knowing what your missing as much as the machines capability's.
the miller 140 amp is a darn nice tool that will do most of what you need to do, if I was only doing welding rather rarely its just fine, and Id certainly feel it was meeting my needs, but
after using both friends welder I saved up and purchased a miller 252 mig and am currently saving for the TIG ADAPTER PARTS for my LINCOLN ARC WELDER

my neighbor has a small Lincoln mig, he uses mostly as a flux core welder and he was thrilled with that, but he still comes over to have me weld much of the stuff he does as hes noticed the difference in the weld quality between the small Lincoln and my larger miller.

If my e-cig is smoking, something is seriously wrong with it.

FINE EXAMPLE of CRAP QUALITY WELDING IN A CAR RESTORATION
 
I cant tell what failed Grumpy.
Was it a Dana 60 Mopar rear diff that flew out ?
Mopar musclecar torqueboxes are made strong.
I recall the front spring eye bracket bolts up to the rear torque box in a Hornizontal Shear plane. Opposite of GM F Body Leaf spring.
Welds may have failed.
Definitely a wild ride for the guy in the Dodge Dart.
Its a good thing no Mopar Guys are here.
Chevy & Pontiac & Olds- Gasser Willy & me too.
 
the stock dart rear during that time frame was similar to the first gen camaro and nova rear differential leaf spring set-up
looking at the sequence of events and knowing how the differential mounted .Id suspect the drive shaft rear u-joint broke , the differential rotated downward in the front, as he hit the brakes hard, that differential,u-joint dropped , dug into the pavement , the cars inertia popped the differential u-bolts holding it to the springs, they broke then the spring hangers sheared

A front and rear Driveshaft safety loops would have prevented the bad mishaps .
And Napa store bought Super Duty Brute Strength Spicer U-joints or Neapco brand U-joints.
I am a believer in safety gear from dragstrip onto a street toy race car.
