They're my go-to for top-quality welds!
“I’ve used Heavy Hitter TIG rigs since 2019, and they’ve never let me down—no overheating, no gas issues, and perfect results on metals like Titanium and Aluminum. They're my go-to for top-quality welds and procedure qualifications. Even veteran welders I introduced them to years ago still won’t use anything else—that says it all.”

Never let me down!
I’ve been using a Heavy Hitter Rig since they came out. I use it for everything I weld, from Schedule 10 to XX Strong. It’s never let me down! It’s really shaved man-hours off heavy wall welds and never gets hot. It helps streamline my work, and it’s easy on my hands by keeping the heat down. Highly recommend one for the heavy wall welders out there!!!!

The best TIG torch you will ever use!
My students and I are sold on the Heavy Hitters TIG rigs; they are well built and by far the best TIG torch you will ever use."

Durable, lightweight, and great gas flow!
"Heavy Hitters are durable, lightweight, and have great gas flow. Fill quicker and cap slicker is an accurate statement for these Heavy Hitters. If you’re a TIG welder and don’t have one, you are missing out."
