What’s in the Box?

On opening the package, you will find the following:

  • An operator Manual.
  • One 8 ft. primary cord with multi-voltage (MVP) plugs for 120-volts and 240-volts.
  • A regulator/flow gauge and gas hose.
  • An RFCS-RJ45 remote foot controller.
  • A 12.5 ft. (150 inches) Weld craft A-150 Tungsten inert gas torch.
  • A 12 ft. (144 inches) work cable and clamp.


The following are the features of the welding machine.

  • Ease of Use

It brings with it, and easy-to-understand operator interface. It guides users through the easy set-up procedure. After powering up the machine, you can preferentially choose the type and thickness range of the material you want, and that’s all you need to get started. You also get to see all settings options chosen displayed on the digital screen. Then, based on the settings, the system will supply a suitable quantity of arc welding current.

  • Dual-Voltage feature

This machine works on dual voltages. The dual-voltage plug feature permits connection to either a 115 volt or 230-volt receptacle based on the simplicity or complexity of the welding work. It is also quite easy to switch between these voltages, without altering any settings, all you need to do is to select the appropriate plug for the receptacle that you want to use and connect the power cord.

The maximum output current for the welder is 180 amperes (amps), and with this machine, you can weld non-stop for up to 4 minutes using full power, after which it will require about 6.5 minutes to cool.

  • Lightweight

Weighing 50 pounds, Miller Diversion 180 welder is qualified to be considered a portable welder. It can easily be carried from one work site to the other. Also, it is not large and wouldn’t occupy a significant amount of space within a workshop or garage. However, despite being compact in design, its functionality and power are not affected.

  • Low power consumption

This welder does not consume much power. Efficient power management is made possible by the presence of a Fan-on-Demand feature, which functions by minimizing noise levels, eliminating debris, dust and prevents harmful particles from getting into the machine.

  • Versatile

This machine is versatile because it is capable of different welding types of metallic materials such as aluminum, stainless steel, weld steel, etc. as long as the thickness of these materials falls within 3/16 inches.

  • Performance 

The performance of this machine is enhanced by some features such as:

  • Auto post-flow, which automatically regulates the post-flow according to the welding output. This feature also allows for the shielding of the electrode and weld end zone, thereby hindering the wastage of gas.
  • Advanced square-wave alternating current (AC), which delivers deep penetration plus freezing (cooling) of the weld surface
  • A Diamond Head grip that lets the user handle it, without difficulty or fatigue comfortably.
  • The air-cooled torch guarantees its durability.
