Gas Tungsten Arc Welding (GTAW) or TIG welding, can be very difficult for new welders to master, especially without formal training. Today we are going to discuss and demonstrate some proper techniques and drop a few tips to help even the most novice of welders master the lap joint.
In an effort to educate the masses on the restrictions of short circuit GMAW transfer we decided to do a fillet weld break test in the shop on some 3/8" plate. Over the course of my career, I have been in many shops where short circuiting MIG has been used on materials thicker than 5/16".
Today we are going through the functions and capabilities of the new Everlast Lightning MTS 275 Multiprocess welder. Our objective was to test the low lab amp capabilities of the machine and go through the different pulse options and AC frequency capabilities. Prior to the video, we went through the different processes the machine is capable of running and and got familiar with the settings.

The joint configuration is similar to the horizontal plate except we now have both plates beveled at a 22.5° angle for a total of 45° included angle.
There seems to be a huge disconnect amongst the younger generation of welders when it comes to (CJP) prequalified weld tests, structural applications, and Flux Core Welding. I never realized how many "welders" didn't understand the aforementioned topics until we released this video.
