Welding Power

The Hobart EZ TIG 165i power cord is plugged into a power source of 230V of input power which means that you can not run it on a regular home outlet of 110/120 volts but it will give you a consistent welding arc when TIG welding.

It has a power output of 165 amps which is very good and enough to successfully weld materials of up to 3/16 in thickness. The machine also has a decent amp output on the low end with a minimum of 10A which is good if you are welding very thin metal sheets or pipes.

The duty cycle is not that great sitting at 20% at 150A output but considering that this machine is meant for lighter use it will be good enough for home or shop use.

Ease of Set Up and Use

The Hobart EZ TIG 165i is very easy to use welder. Welding with it is as simple as it can possibly be. All you have to do is to choose the material you will be welding and the welding thickness and that’s it. It is all done in mere seconds right on the front panel. Controls are very intuitive and beginner-friendly which makes this welder a great learning machine.

Hobart EZ TIG 165i Features

Just because this welder is not meant for heavy use it doesn’t mean that it doesn’t have some interesting features.

First of all, it is an AC/DC TIG machine which means that it can weld anything from stainless steel to aluminum. It also supports a non-contact HF arc start which is reserved for high-quality TIG welding machines.

You can fine-tune your welding amperage thanks to its infinite amperage control and there is also a fan on-demand feature that extends the life of your Hobart EZ TIG 165i. The welder also has the ability to provide automatic post flow of shielding gas so that you don’t have to worry about it.

There are however no AC balance, pulse, or frequency settings. This is good for the beginners not to confuse them or for people who don’t need that but being able to set those things yourself can be very helpful for more demanding work.

The Build Quality and The Price

Hobart is a United States-based company and its quality is well known among welders. The Hobart EZ TIG 165i is no exception. This welder has an outstanding build quality and it will last you a long time. The TIG torch and foot pedal are both of good quality as well.

The price of this machine as I said earlier is higher than your average TIG for light work and beginners but this machine has Hobart’s 5/3/1 warranty, excellent arc quality, it is AC and DC and it is of high quality meaning that it will last you for a long time.


This welder will not let you down considering that you use it for what it was meant for. Considering everything they put together in this product and the quality of it, it is certain that you will get years of great welding experience.

Regardless if you need to weld aluminum, stainless steel, or mild steel this welder is ready to weld. Just keep in mind its maximum amperage output if you need to weld a material thickness that far surpasses it.

This is a great welder for beginners and for lighter pro use and if you decide to go with it you won’t regret it.
