Financing

We offer three different financing programs. You can start welding today for as little as $19.95 a month.

Also, be sure to ask about our consignment machines and trade-in/trade-up program!

Free Add-Ons

When you purchase a machine, we’ll provide you with a 20CF cylinder filled with argon or an argon mix. That’s enough gas to weld for about an hour.

All machine purchases come with a discounted weld class. Sign up here.
