Welders (39)

Our portable or trailer-mounted arc welders for rent range from 150 to 700 amp watt capacity, with 2-in-1 machines offering both welding and generator power. United Rentals’ welders inventory is great for a range of jobsites where electrical outlets aren't readily available.

Welders FAQs

What is the difference between arc and argon welding?

  • Argon is a type of gas used as a shielding agent to protect welders from extremely high temperatures. It is applied to the metals to prevent a reaction from the heated metal with the rest of the components in the air like nitrogen, oxygen and hydrogen. Argon gas also maintains the stability of the arc.

Is arc welding the same as stick welding?

  • Stick welding — also known as shielded metal arc welding (SMAW) — is one of the most common types of arc welding and uses a flux-coated electrode (the stick) to form the weld.

What's the best welder for beginners?

  • United Rentals offers a range of welders by top manufacturers. Our experts are here to help you find the exact piece of equipment for your preferred arc welding method and project need.
