Cut Off Guide for a Circular Saw

Step 5 The third weld

The third weld attaches the long guide piece to the angle iron. I made a light tack weld and also used a plug weld. A plug weld is made when the welding rod is pushed down into the steel at a considerably higher than normal amperage, melting a hole as you go. Then you back the electrode out of the hole, filling it as you go. The tack weld is on the side of the guide piece opposite the side against which the saw base rides (left side of the bar as shown).
