^^^
Why not disconnect both battery terminals, and short +ve (the cable, not the battery terminal!) to ground?

Thicker members definitely needs electric welding and is better if the electric circuitry is isolated by removing both the leads of the battery. Another very important aspect is to have a firmly connected earth of the welding machine to the car to avoid ocurrence of sparks which can cause damages to any film contact components like bearings.

For the last one week, my Jeep has been welded atleast one or the other place every single day. The only thing we did was to remove the -ve terminal.

However, seeing the Jugaad methods being followed for welding, there are one too many sparks in undesirable places. Hence, I'd suggest to remove both the terminals, and make sure NO current flows even in moist air.

If so, IMO, you can be sure not to damage anything.
