The vise is fairly self-explanatory. The miter joint at the bottom has a quick-release button on its screw that allows the jaw to be quickly adjusted. The second clamp is on a swing arm so that it can be moved aside when materials are being fixtured, and it too has a quick-release button for fast adjustment.

The main thing to be careful about is making sure your material is held at the correct angle before welding. If you are using tubing that is significantly smaller than the height of the jaw clamp, then tightening the clamp will tend to force the material out of alignment. The simple fix is to use spacer tubes to make sure the entire face of the clamp is engaged.
