welding on bike

[oilspot]

I just got my "new to me" freshly rebuilt wer damper. I've got the unit bolted on the bike and just have to weld the bracket onto the frame.
My question is about the electronics on the bike. Is there anything I need to disconnect or remove before I start welding. I'd really hate to toast something.

completely disconnect the battery if it has one.

what about the cdi?

A welding apron to cover the rest of the bike.

I would take off the coil,cdi,and pick-up by the rotor!! Some rumor that a good ground near the weld,but it could get expensive.

If you are wire welding or tig welding using DC straight polarity, you don't have to disconnect anything.

If you are welding aluminum using AC, High Frequency, it is a good idea to disconnect the CDI unit.

Just my $ .02

ok here's my dumb question! I'm using a hobart 135 mig welder, running gas. I know the welder runs on AC but don't know what the weld output itself would be considered AC, DC and have no idea about polarity.
I just think of my little MIG as my hot glue gun for metal. I was given a crash course in heat and wire feed settings when I got the machine. I've managed to stick everything together that I've wanted to, but have held off on building bridges or any life saving devices with it :) .

It's the high frequency that you have to worry about. A Hobart 135 mig machine doesn't have high frequency unless it has a buzz box added to it. If you have any doubts, just disconnect the wires going into the cdi box.

Don't worry about the bike...you'll only damage any of the electronics if you pass current through them. Welding a damper on I seriously doubt you'll cause any issues. It'll be good to take and damp rag and cover anything in the vacinity of your welding...especially painted and composite surfaces. Welding slag (the hot splatter off the bead) will be your only real concern and it is quite damaging.

Hook up the ground as close to the weld as possible, you don't want to be transmitting current through the steering stem bearings. It will pit the surface.
