Everlast Lighting MTS 275 AC/DC TIG Review

GTAW | TIG

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.

We started off doing some razorblades to test out the low amp arc initiation, we got dialed in at 40 amps and welded a set together just to see how well it would perform. Overall, it welded great with the lower amps, We then set up some 16ga. stainless steel and checked out the pulse functions. For our initial test, we ran 1 pulse per second on an outside corner joint, the machine performed well, but due to the low pulse setting I had to run a bit slower than I would have liked to. The slower travel speed caused a higher heat input which caused some sugaring on the back of the weld joint. This is no fault of the machine, I just think 1 pulse per second would be better suited for thicker material. We then jumped up to 75 pulses per second and I was really impressed with the way that it functioned. I was able to run faster where I normally would on stainless and there was no sugaring on the backside like we had on the 1 pulse per second. The weld turned out very well and we decided to go ahead and max out the pulse settings and see what 150 pulses per second would do for us. The User Interface of the Lightning MTS is pretty intuitive, your major settings are all listed on one screen so you don't have to go around looking for sub menus to make adjustments. There are a couple sub menus in the system but they are easy to access and are items you really don't have to adjust frequently like whether you intend to use lift arc, High Frequency etc. We went back into the menu and ran the pulse to maximum (150Hz.) Once again, the arc initiation was very stable and the machined performed well yet again.

With the low amp stainless out of the way, we set up an outside corner joint with some 16ga. aluminum to test the frequency capabilities of the Lightning. I decided that 60Hz. would be a good place to start because most rectifiers run on 60Hz. At 60Hz the weld turned out okay for the most part but the bead was a little too wide for the joint we were running. Once we stepped up to 120Hz. the bead profile narrowed out and produced a very appealing bead. The max 200Hz. yielded a slightly narrower bead then the 120Hz. If I had to use it daily for this type of joint on 16ga. I would say anywhere between 120Hz. and 200Hz. would be a good setting for this type of work. I also noticed that I could travel much faster with the increase in frequency. 

Overall the Lightning performed very well on AC and DC.
