I used the “Fireball Method” to remove the weld from square tubing for the first time today. 1/4" thick by 2.5" square that was 30" long…to nest 2 inch by 1/4 wall square tubing. Gotta say I was skeptical…but it works very well. Kudos to Jason for sharing this method. Overall, it was very easy to make the jig. The hardest part was grinding the high speed steel cutter to length and keeping it square…with a handheld angle grinder…while keeping it cool. Would love to hear any of any tips or jigs folks use for this. I made two passes and found the second pass improved the fit quite a bit. Super smooth when done and tubes nest nicely. Thanks Jason!

Hi I’m a diyer and was trying the method that Jason used to remove the weld seam from square tubing. My problem is the impact wrench that I was using didn’t have enough torque to fully pull the slug through. I used the Milwaukee M12 Fuel impact wrench with about 500 ft pounds of torque according to the specs. I was wondering which impact wrench Jason and anyone that used his method used to remove that seam, or what torque rating is needed. I can see the small sliver of seam, about 1/4” that was raised by the cutter, but the M12 couldn’t pull the “slug” through. Any info would be greatly appreciated. Thanks.
You might have to cut the weld out in two passes depending on how big the weld seam is. You can reduce the engagement of the HSS to reduce some of the load.
