How To TIG Weld: The Tools Of Our BuildsPosted in How To on December 1, 2011 Comment (0)
We love tools. The amount of tools we use on our projects is mind-boggling. Without a doubt, some tools are way cooler than others, and those are the ones we look forward to using. Our Scratch-Built Scrambler has been a long time in the making; we started documenting it in Nov. ’09. A number of components have been prototyped and installed, only to be removed. We are continually making structural change to the body or frame, so welders and plasma cutters are always in hand. Our Jeep’s Aqualu aluminum tub has had more holes drilled in it than necessary. To fill them, we could have used a spool gun, but some of the guns are messy and make cleanup a chore.
Looking for a better way to finish off the Jeep’s tub, we contacted Lincoln Electric and ordered the company’s new Square Wave TIG 175. TIG (tungsten inert gas) welding is considered a step up from MIG welding. A TIG welder produces a clean and precise weld with no splatter, perfect for intricate and detailed welding. Getting into a good machine is usually quite expensive, but the Square Wave retails for $1,849 and is a great investment for enthusiasts and shops looking to lay better welds on their projects and products.
We took the Lincoln TIG welder to T&J Performance Center in Orange, California, to test it out and let the fabrication technicians use it on some of their projects and high-end desert and Jeep Speed race cars. The T&J techs are expert welders, so we wanted to see what they could do with our new machine.
The Square Wave TIG 175 is recommended for TIG (GTAW) and stick (SMAW) welding within its output capacity of 10 to 175 amps, on both AC and DC polarity. The machine is a constant current single range AC/DC arc welding power source. It features a built-in arc starter and stabilizer. We were thrilled to play around with the TIG and use the Square Wave on the Scrambler. The machine closed the unneeded holes on the side of the tub without a disastrous mess of splatter.
We’re looking forward to using the machine on more detailed metal and aluminum work and were impressed with the Square Waves out-of-the-box ease of use and quality TIG welds.
