AC or DC, the battle is deep. It was not going to solve. So, companies started to make welders with both AC and DC voltage. A lot of modern welders come the same way. In general, people prefer AC for Aluminum and DC for steel.

Duty cycle

Will the welder get cool in a short time or take long hours for it? The duty cycle will tell you. The more, the better; however, with more price. If you are buying for home use, the lower may be ok. On the other hand, if you need it for workshop use, invest in a higher duty cycle percent.

Weight and size

Compact size, handle on top, and light in weight makes the perfect combo. If your TIG welder possesses these features, then you are good to go. But if it is heavy, then you need to ask yourself, “can I handle it?”. If the answer is no, then stick to the light machine.

Thickness of metal

Don’t ignore it. It matters a lot. You should know if you are working on thin metals or thick. A lot of people work on thin metals. They are cheap, so people prefer to buy them. However, if you work on thick metals, then you should buy a welder that supports it.

You should know that you can’t go to an extreme rating. So, if maker claims ¾ inches, you shouldn’t go above half an inch. Use your welder device care, so it remains durable.


Last but not least, price. You will find a lot of models. While some of them are from the elite section, there are many quality welders at less cost. You should decide if you need a brand name or peace of pocket.

I can guide you about some best yet affordable welders. Go with Lotos or Prime weld, and you won’t regret it. Not only are the best TIG welder for Aluminum, but also less in price. Apart from this, check our hand-picked list of best TIG welder for the money.
