TIG welding, standing for Tungsten Inert Gas, or also called Gas Tungsten Arc welding (GTAW), is considered the more suitable and traditionally used metal-welding tool for professionals.
Instead of a continuous feed of a wire, TIG welding uses an electrode in the form of a long rod that gets fed slowly into the device, feeding them into the weld puddle. For this reason, it doesn’t have the speed of weld that MIG Welding does, but is instead a slower, more detailed process.
This pace makes it a much more effective choice for thinner gauge materials like stainless steel, aluminium, magnesium, nickel, titanium and copper alloys. It also allows for more precise and smaller welds, making it a choice for professionals that to do work in fine detail.
Some of the major differences between different TIG welders to consider include the pulsing rate of the welder. TIG welders have become cheaper recently, meaning that more people are getting access to this form welding. However, the cheaper models come with a lower pulsing rate, meaning they have less control over the amount of heat applied. The more you can control the heat, the cleaner a weld you will have and the faster your weld rate will be.
There’s also the question of portability. TIG welders are, in general, much more portable than MIG varieties, but they come in different sizes and weights. 40lb. TIG welders are easier to move around for versatile jobs. However, there are units that weigh well over 100 lbs. These devices offer a longer duty cycle but have to be transported on a wheeled cart.
It’s worth also considering the metals you need to work with. DC Only welders offer most of the capabilities of their AC/DC powered cousins, except for the ability to work with aluminium. It’s down to the user to decide which metals they need to be able to work with.
The greatest advantage of a TIG welder is the non-consumable electrodes that aren’t required to stop in order to replace them, meaning flawless and efficient joint creation. There’s also no need to shield the metal from oxidation as the inert gas does that itself. Higher-quality, more detailed work, and a greater portability also make it a strong choice. But at the end of the day, if you need to work with finer, thinner gauge metals, the TIG welder might be the only viable choice.
All welding devices have their downsides and TIG welders are no different, of course. While choosing a welder with a higher pulsing rate allows more temperature control meaning you can improve your work-rate, TIG welding is slower than all the other varieties. It’s also a complicated tool used for detailed work so it’s not suitable for novices like MIG welding is.
