There's three or more different potential issues/scenarios here, depending upon if AC stick welding or using one of several DC welding processes.
With AC welding, there's a possibility for CONTINUOUS AC voltage to be INDUCED in wiring and electronics on the machine as long as welding current is flowing.
With DC welding, there would simply be a "spike" every time the arc is initiated or stopped.
Then there's another scenario, with either AC or DC welding where a ground is not connected properly and actual WELDING current (rather that INDUCED current) flows through the machine frame and mechanism and/or electrical system.
Several times over the years I have read instructions for various equipment that stated "If necessary to weld on this machine, disconnect battery cables and short/clamp them together".
This makes WAY more sense to me than disconnecting the (+) battery cable and simply allowing it to dangle. Doing that (to me) is worse than leaving it connected because there's NO limit on voltages that MAY be induced in that open circuit by AC welding.
With the battery still in the circuit, there's a BIG damping effect on stray voltages, as it takes AMPS to push around the battery's voltage, and not NEARLY so much current to fry electronics!

Today's Featured Article - The Nuts and Bolts of Fasteners - Part 2 - by Curtis Von Fange. In our previous article we discussed capscrews, bolts, and nuts along with their relative hardness and thread sizes. In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and
