Welding Tips and Tricks

I've done a little back purge before...I know how to hook it up...but when I worked for a former employer they had a box with holes in the top. We had em in all shapes an sizes. I saw one of Jody's videos talking about em....but not how to build one. I was hoping someone might have a pic an some easy instruction on how to build one. I think i just need a sm all one maybe 2x4" or maybe 3"x4"...any ideas on materials and diffuse material and all that....Id really appreciate some help on this!!! Thanks for any ideas

Should be pretty easy to put together.

There are some images for back purge boxes etc here: https://www.google.com.au/search?q=argo ... 3&bih=1032
