Welding Checklist

In addition to making a very good ground connection next to the welding area you may also do the following disconnecting/unplugging to keep sensitive electronics safe. At a minimum do remove the positive and ground cables on both house and chassis battery(s), and place the ground clamp as close as possible to the work.
