Hobart EZ-TIG 165i Features

Ease of Set Up and Use

Hobart EZ-TIG 165i reviewEveryone values simplicity, no matter if you’re a novice or professional welder. And you’ll be happy to know that this Hobart welder was designed with simplicity in mind.

It features a simple interface that offers 3 options:

  1. Power: On/Off switch.
  2. Amperage/Thickness knob: here you just need to choose the thickness of the material and based on that the amperage will adjust itself.
  3. Power output: AC/DC switch.

AC and DC Output

This TIG welder offers the capabilities of both AC and DC welding. This gives you the ability to weld a bigger range of materials. Using AC output, for example, you can weld aluminum or magnesium. DC, on the other hand, can be used to weld mild and stainless steel.

Infinite Amperage Control

The welding amperage range for this welder is 10A to 165A. The infinite amperage control means that you don’t need to round up the amperage to 5 or 10 increments, but instead, you can adjust it to your specific needs. With more precise control of the amperage, you can more consistent welds.

High Frequency Start

The EZ-TIG 165i welder features a high frequency start, which is a non-contact arc start. It starts the arc without the tungsten coming into contact with the workpiece. You just need to hover the tungsten over the workpiece at a distance of about ½ inch, then by pressing a foot pedal, you can initiate the arc.

The advantage of the high frequency start is that since there’s no contact between tungsten and material, it helps to eliminate contamination in the area.

Fan-On-Demand

hobart 165i control panelIt’s an important feature for any welder. This technology works by turning on the fan only when so required. The benefit of this is that reduces energy costs, reduces the amount of noise in the workshop, and prolongs the life of the machine in the long run. Without this feature, if the fan would be constantly running, this would cause debris and dust to be sucked into the welder. Over time, it would start to overheat and not work properly.

Overheat Protection

One of the safety features of this welder is the automatic high temperature shutdown. When the unit reaches the certain temperature limit, this Hobart will automatically shut down and will stay off until it’s cool enough again.

Duty Cycle

The duty cycle is rated at 20% at 150 amps, which we have to admit is a pretty short duty cycle and can become a hassle if you work on a tight schedule.

Inverter Based Design

There are two main benefits of the inverter based design. The first one is the much smaller size in comparison to cumbersome and heavy transformers. The inverters are designed for portability.

Another advantage is the efficiency of the inverter, as it packs a lot of power into a small unit, using special technology to store and disperse the energy. So the result is more power and a more stable arc.

Auto-Post Flow

This feature provides the weld pool with optimum shielding gas, which it determines based on the amperage used. This helps to reduce waste and time for adjustments.
