Welding safety that is not obvious: the fires start after you leave

Spatter smolders in sawdust, cardboard and rags for an hour before it flames up. Sweep the floor before you weld, keep a water bucket and an extinguisher, and do a 30-minute walk-through after you finish. Other things: never weld on a drum or tank that held anything flammable (fill it with water or argon first), never weld on a vehicle without disconnecting the battery, do not use a damp floor, and cover the window glass or you will see the arc burns in it forever.

Should be the same procedure, the part moved slightly but the steps match.

Followed along, got it done in about twice the time quoted, but it is done and it works.

Unplug it. Always. Takes two seconds and the worst case otherwise is a trip to the ER.
