1. Ideal for Outdoor Welding

Due to its flux-cored feature, the Century FC 90 welding machine is perfect for outdoor welding. This function allows for deep penetration into thick materials, ensuring a strong and lasting weld even in windy conditions.

Its compact and lightweight design contributes to its outdoor suitability because it’s easy to transport to various job sites. The machine’s robust construction withstands different weather conditions, ensuring reliable performance wherever you are.

Its ability to handle up to 1/8 inch thick materials makes it ideal for various outdoor welding applications.

2. No Shielding Gas

The Century FC 90 welding machine features No Shielding Gas, ideal for users who prefer simplicity and convenience. This feature eliminates the need for costly and bulky shielding gas cylinders, making welding easier and more cost-effective.

It also allows for outdoor welding without worrying about wind blowing away the shielding gas. This makes the Century FC 90 a versatile machine, suitable for indoor and outdoor use.

Field Testing

I recently had the chance to field test the Century FC 90 Welding Machine and was pretty satisfied with its performance. This welder’s compact size and portability make it a great tool for on-the-go projects. It runs on a 120V power supply, making it suitable for home use or in places where high voltage isn’t readily available.

The Century FC 90 uses flux-cored wire, eliminating the need for gas. This makes it much more convenient, especially for outdoor welding jobs where wind can disperse shielding gas. The machine impressed me with its ability to handle up to 1/8-inch thick materials, making it suitable for light to medium-duty tasks.

One downside was the machine’s duty cycle. It’s rated at 30% at 90 amps, requiring resting periods between uses, which can be a bit inconvenient for larger projects. However, for its price range, this is to be expected.

Overall, I found the Century FC 90 Welding Machine a reliable, user-friendly, and cost-effective tool for anyone needing a portable welder for lighter tasks. Its performance and ease of use make it a worthy addition to your toolbox.






Value for Money:


Overall Score:
