Hey guys looking for some advice i original welded my canopy but for months have not been happy with it so today i decided to change the legs and now i like the design, just wondering what i need to do to weld on a boat i know disconnect the batteries but what about everything else electrical?

at the moment the legs are duct tapped on but the leg braces are welded however the legs are not attached to the top this is what i want to weld on the boat so everything is square
