Welding repairs

[raveson]

Does anyone have any info as to the possiblity of damage to the electronics and or batteries if you have any heliarc welding done to external parts of tne coach? I need to have a repair done to the screen door hinge, and the welder cautioned me to disconnect batteries before proceeding. Even with batteries disconnected, what are the possibilites of damage to chargers/univolt or other equipment? I had my old 66 tradewind worked on many years ago without any problem, even without disconnecting, but there are many more things to get destroyed on my 345. To get the door off is a real pain and I would prefere not to unbolt the door hinges as I have been there fixing the bolts ( annother real pain)! Again thanks in advance for any info!

Disconnecting the batteries, is a safety margin, just in case.

As long as the coach is not plugged into a source of electricity, the univolt will be fine, along with everything else.

Also, turn off the the propane at the bottles and drain the lines of stored propane by turning on a stovetop burner after turning off the propane at the valve(s). Let the flame go completely out and then turn it off.

All depends on where he places the ground cable. The path of the current will be from the "torch" to the ground cable. If it's close, it should not be a problem. If it is far there will be a bigger antenna for the magnetic field.

To minimize any gap arcing across a hinge I would suggest having him/her attach the ground lead to the part being welded.

Does anyone know the material alloy?

Best of luck,

Kevin

It may be 2024, which is not weldable. Too many alloys. Didn't think of that the first time.

I do not know what the alloy of the hinge is, but I do know that it's not 2024.

I have done some welding on my door frame with my neighbors heliarc and had no problems.
