Step 2: Turn on and grounding the machine

Before you turn the machine on, you are going to want to put your ground clamp in position.  You can ground to the table that you will be welding on, or you can ground directly to your piece.

After your ground clamp is in place, you can turn the machine on.  Be careful when you turn the machine on, the electrode holder (torch) is now HOT HOT HOT!!!
In the photo of the Lincoln welder the electrode holder (stinger) has an extra "U"-shaped piece welded to it near the end. What is its purpose? I have not seen that before. Thank you.
Good eye Phil! The plastic piece that shields the hot part of the electrode holder broke off. I welded those two U-pieces on the electrode holder so you can set it on the table without fear of the bare electrode holder striking an arc to the welding table.
Thank you. That makes good sense.
