Welding The Ultimate DIY Giant Square With Langmuir Systems And Arccaptain Mig200!
Building a DIY mega square with my langmuir systems and Arccaptain Mig200.
I needed a larger mega square or similar combo square and found a file to cut that was perfect for this project. The link to the DIY square is below.
I used my Langmuir systems crossfire and my Arc Captain Mig 200 to build this project. The square is easy to weld and is very sturdy with the 3/16 mild steel used.
