Top Features Of The Vulcan OmniPro 220 

Well construction and excellent versatility 

Made from industrial-grade aluminum, the drive system of this machine is sturdy and durable enough to handle a wide range of metalwork. Besides, it uses inverter technology, which means energy waste is eliminated while efficiency is enhanced. 

One of the key criteria to look into when buying a welder is the wire feed speed (WFS as shown on the LCD). Measured by IPM (inches per minute), it controls the welding current while regulating the amount and speed of wire fed into your welding joints.

A higher speed than required can cause burn-through, whereas low speed can lead to poor arc starts and tie-in welds. 

The Vulcan OmniPro 220 comes with a WFS of 50-100 IPM, which significantly improves your efficiency. This WFS rate also makes it one of the most versatile welders for multiple projects, be it industrial job sites or light-duty tasks home workshops.

Great convenience with dual voltage


With dual-voltage technology (120V and 240V input), you do not need an adapter to use it in multiple applications, whether your jobs are indoor or outdoor. 

Better still, it can work effectively on both voltages without the incurring costs of additional welders. When operated at 120V, you can join light metals perfectly. With higher penetration of 240V, you can tackle more challenging tasks as the output is increased with more power.

Handle a variety of welding tasks

As a multipurpose welder, this Vulcan tool provides various welding tasks on different materials: stainless steel, DC TIG, Flux-Core, cast steels, DC stick, MIG, aluminum (if purchased the spool gun that sold separately), and TIG welding (thanks to the included 150A TIG torch). 

Given this, it is a truly versatile device – a perfect choice for both home projects and repair workshops.

Additionally, it features a large LCD of 4.3-inch, offering an easy switch between 132 different settings for various welding tasks. This bright screen also allows you to monitor the overall operation of this welder to prevent potential problems from occurring during the welding process.

After plugging the welder into your power outlet, you only need to turn the switch on to start working. 

From the main menu, users can quickly choose the right setting for their welding materials. Simply spin the biggest dial in the middle to switch from MIG, Flux-Core to MIG for stainless steel, Spool Gun (for aluminum welding), then TIG, and a few others. 

There is an orange chart on the left side of this unit that shows basic information, duty cycle, and all wire settings. So it’s super helpful, especially for those just starting out, as you don’t have to remember all of these details. 

Last but not least, this device also comes with an exclusive memory feature to give you an instant recall of previous settings. 

Some notices before using the Vulcan OmniPro 220

The manual from the manufacturer provides useful safety guidelines and operation instructions, helping users understand how to best use the welder. 

Given this, while it’s tempting to jump right in and start operating the machine, all owners should read that user guide carefully before getting it started. 

Below are a few things to take note of before using:

  • Proper footing is of great importance. You need to place this tool in a stable location before plugging it in. Otherwise, it might fall and cause electric shock, other severe injuries, or even fire hazards. 
  • Weld with attention! Avoid using it if you’re lacking sleep, tired or drunk. Also, always turn it off when you’re away and keep it away from children. 
  • Wear proper protective equipment to keep yourself from fire sparks and fumes. So a welding helmet, a filter shade, a jacket, ear-plugs, fire-resistant shoes are all necessary items that you need to wear before welding.
