I received my Anderson Hitch package from RadAuto.com on Monday afternoon (ordered Wednesday noon}. Installed it today twice. The first time the sets screws did not hold. I drilled holes on the outside of the frame to seat the set screws on the frame rail and reasembled. The second time a short test drive found that the frame brackets have moved. I plan to have the welding option in the instructions completed tomorrow. The test drive was good though The ride seemed firmer with less bounce and noise. There were 35-50- mile andn hour winds, but I was in town and uder 40 MPH. Howerever I noticed NO SWAY.
My BIG question is when I have this arcwelding done on the bracket to the frame tommorrow, is there any precaution that I must take like taking the negative ground cable off the battery to protect electronics on board?
I would appreciate your thoughts as soon as possible before the welding of the brackets tomorrow.
Thanks

It's always a good idea, as it will make damage to electronics inside the trailer less likely, and also prevent the discharge of hydrogen gas from the batteries charging if the trailer is plugged in. Damage to electronics is a unlikely, but it's easy insurance to reduce the chance of it happening. After all, RVs aren't exactly known for high-end components inside.

Coincidently when I'm welding on my TT I use the same cord for the TT as I do for my wire feed welder. I also have a battery disconnect switch. But yes you should. I really don't know what could happen but better safe than sorry.

Thanks,
I forgot that I have a battery shutoff that I will use on your suggestions. That should do it.

As a welder, I would make a point to unhook any batterys. Both sides just to be safe. Far easier and cheaper than replacing things. Murphys law seems to always kick in on these things.

Ditto on unhooking BOTH cables! Sometimes not everything shuts off with the batt disconnect. CO/Propane detector comes to mind.

IMO DISCONNECT BATTERY at battery itself unless POSITIVE that disconnect switch removes ALL connections. A battery is pretty much a short for high freq pulses. You do NOT want those to get to a control board.

Some years back I welded a hitch on a rig with the ground disconnected and shorted out all the lights ect.. We figured out that even with the ground wire unhooked it must have shorted from frame thru the battery case to the plates and blew the fuses ect. We never thought of it grounding that way. So now unhook both sides..

Yes, definitely need to take extra precaution when tig welding aluminum with AC and high frequency, wherever there are electronics connected to the structure being welded. HF can wipe out computer electronics easily.
Common arc welding or wire feed welding is much less of a risk, but precaution is still always a good idea.
