AC and DC Output 

AC and DC Output Hobart EZ-TIG 165i

It is an AC and DC welder. Hence, it opens the avenue to weld a range of materials. The AC can be used to weld materials like aluminum or magnesium. DC can be used for stainless steel welding.

Infinite Amperage Control 

This welder has a broader range of amperage control. It can output 10 A to 165 A, allowing you to set your current amperage settings finely. With this finer control, you can get better welds.

High Frequency Start

Another great feature offered in Hobart 165i is the High Frequency Start feature. It allows for a contactless arc start. Using the HF arc start, you can initiate the arc without contacting your piece to be machined. This feature helps to prevent the contamination of the material.


One constant fear of welders is the dust and dirt which get piled up in their workspace. It can get inside their welder units and hamper their performance. And eventually, it can reduce the lifespan of the unit. The fan on demand feature of Hobart EZ TIG 165i helps to solve this problem. 

The fan can be allowed to run when needed. It reduces the possibility of dust entering the welder unit. The fan on demand feature also helps reduce energy wastage and extends the life of the unit.

Overheat Protection

The apt Overheat Protection feature of this welder gives it an edge over others. The machine is designed to stop when it starts getting overheated automatically. It is one of the safety features of a 165i welder. This helps prevent any damage to the machine from excess heating and saves from high repairing costs.

Duty Cycle

Unlike its other features, the duty cycle of the welding machine is not that impressive. Its duty cycle is 20% at 150A. Hence it cannot be of great use for heavy welding jobs. But it would be suitable for home use.

Inverter Based Design
