Outer Limits 4x4 Board

Hi all

I want to do some welding on my camper trailer that has a battery and electrical appliances.....should i discinnect battery on it?

for the 2 secs it takes why not ?

You should always disconnect any batteries and ecu's electrically connected to whatever youre welding. If however the battery in trailer is not connected to chassis, you dont have to unless there is a risk of residual fumes from battery igniting (if it has been heavily charging or discharging)
