I am wanting to do some welding on my TT (2012 crossroads) and I was wondering if I need to unhook the battery before doing so. Also is there any other precautions needed to protect the elec./comp. systemsThanks, Joe

First, check out the propane and keep away from it or any lines. Make sure you have a fire extinguisher around. Keep away from anything that burns. Disconnect the battery. Keep your ground close to your work, and don't let the current go through your bearings. Depending on what type of welding and where on the trailer you are doing it will determine what other precautions you may want to take. A fire blanket is always nice around other combustibles.

69 Avion hit the critical points. I like to get the ground close to the work, and between the weld and the electronics. Make sure you grind down to bare metal for the ground clamp. What are you welding?

It is simple. A good welding ground, clean weld area. No need to disconnect anything, unless your rig is grounded in some other way. That aint likely, it is on rubber tires. 40 years I've been welding on vehicles and still hear what I think is a myth. Its an engineers cya ,in my opinion.

69 Avion hit the high points. One thing to emphasis when welding on a trailer or anything else. THINK when you hook up the ground clamp. You NEVER want the welding current to go through a hinge, bearing, or ANYTHING that Moved. I say MOVED because, after your done it MAY not move!. Those moveable points aren't meant to have literally HUNDREDS of amps flowing through them!! So you never want any such joint between the ground clamp and the stinger. In fact I don't like welding current even going through joints that aren't welded, even if they are bolted and/or riveted. Unless of course that's the joint I'm trying to weld.

I disconnect the battery.Also move the propane tanks if they are close by. Better safe than sorry way more electronics than before.
