Are there any on bike arc welding precautions?

[phillipabailey]

I work on Mack Trucks for a living and before welding on them we are supposed to unhook all the batteries and unplug all the control modules. Are there any preliminary precautions before mig welding on a 98 Standard?

Done several welds on several Valks, never unhooked anything. No problemos at all.
Snap-on 115V MIG.

I would take the same precautions you take on the Mack trucks,,,, it only takes one damaged ignition control module to make you wish you had taken the two minutes to unplug it.

I would at the very least, disconnect the battery completely, and make sure the leads are not touching anything. Unpluging the ICM is not a bad idea either. So few minuets, lower the risk

I've been told that you should avoid having a bearing between the ground and the striker, because it is possible to pit the bearing.

I too would recommend unplugging anything electrical you can and not allow any welding current to go through a bearing.

Good point, certainly something to be aware of!!

ALWAYS... ground as close to the weld as possible

Yes , if you ground close to the weld, you will be fine.
The electrical takes the path of least resistance. therefore you will not be sending "juice" through the bearings or electrical components.
