Portability at its Finest

For mobile welders, the weight of the welder while not skipping out on performance is a must. This is one of the brightest points of the Loto TIG 140 TIG welder as it weighs under 10 points which is unimaginable considering it gives you the ability to use both 110v and 220v electricity. This dual voltage option means you can tote it anywhere you want while not having to worry about which receptacle can be used.

With most power tools, lower weight means less than optimal durability. For standard use, the this TIG welder doesn’t compromise on durability, but if you’re intending on using it on rugged jobsites it’s something to consider. The internal parts which also includes a cooling system isn’t an issue, but the outers aren’t as strong as other, more expensive models.

Perfect Price for Avid Enthusiasts

At first sight, it’s impossible not to notice the ridiculously cheap price of the TIG 140. For this reason alone, it’s become highly popular with avid DIY enthusiasts, especially beginners.
