Welding tool for metal bars

This model is specifically designed to make welding more easy and more accurate. This design makes for a perfect 90 degree angle between two steel bars with the dimension of a bar with 5 cm thickness. How to work with it? Step 1: put your two bars next to eachother so that they form a 90 degree angle. Step 2: Put the tool on top to make sure it's 90 degrees. Step 3: Weld two points onto the bars and make sure the bars are tight and secure together. Step 4: Pop off the tool and weld the rest of the intersection together.
