Welding Fixture - Mini Positioner

I built this welding fixture last September after seeing a idea on the web. I expanded on the idea making it more adjustable and putting it on a 3 legged stand, capable of handling larger work with the added benefit of positioning the clamped work piece in the best weld position.

Heres the idea that sparked my build.

I am not an experienced welder and my equipment is limited to AC stick welders and flux cored wire feed welders. My welds are best done in flat positions, This fixture allows me to clamp up the work and then position and reposition the work for best weld position, without disturbing the work alignment by repositioning clamps.

Construction is all pipe and pipe fittings with the exception of the table, which is a salvaged engine mount from an engine stand. The table is adjustable up and down and 360* in two planes, horizontally and vertically. I have dedicated 4 C clamps for assembly work and 2 vise quick clamps for flat work .

The next 4 pictures shows the degree of adjustment and the mounted clamps.

The next 3 pictures is an example of the set up for welding a small angle iron frame and the adjustments made for best joint access for welding.
