00:00If you've ever tried to cut a circle with a plasma torch by hand, you know the drill, wobbly edge,
00:05uneven kerf, and a good plate of steel ruined.
00:07So I dug through the listings and pulled the 5 best plasma cutting gauges under $40, ranked by what people
00:13are actually buying.
00:15Let's get into it.
00:17First up, the P80 Circular Cutter Gauge, LGK100 type.
00:22The strong magnetic base is the whole story here, it snaps flat onto the plate and holds while you swing
00:27the torch around, so no clamps, no creeping, no fighting the lead.
00:321550, cheapest one on this list, and with 3844 sold at a 4.9 it's also the one buyers trust
00:39most.
00:40If you just want to stop guessing, start here.
00:43Next is the P80 Linear Gauge, the LGK120, and this one's for straight cuts instead of circles.
00:50It locks the torch to a fixed travel line so your cut stays square over a long run, that's where
00:54hand cutting really falls apart on plate.
00:57$37 and change, the priciest pick, but $3,695 sold at 4.8 says people doing production work think it's
01:05worth it.
01:07Third, the P80 Adjustable Magnetic Guide Wheel Compass.
01:10Best feature is the adjustable radius set at once, lock it, and every circle in that batch comes out the
01:16same size,
01:17which matters when you're cutting flanges or rings all day.
01:223060, 3591 sold, 4.5 rating.
01:25Slightly lower score, but the adjustable arm is something the cheap fixed ones can't do.
01:31Fourth is the Strong Magnetic Base Circular Cutter at 1763.
01:36It's the simple version, magnet holds, arm sets the radius, you cut.
01:412025 sold at 4.8.
01:44If the first one's out of stock or you want a spare sitting in the toolbox, this is the no
01:48-drama backup,
01:49and for under $18 you don't have to think hard about it.
01:53Last, the P80 Round Artifact, the LGK100 Style Gauge.
01:58The thing that makes it different, it works on flame and propane torches too,
02:02not just plasma, 30-amp propane setup, oxyfuel, whatever you're running.
02:072419, 1,358 sold, 4.7.
02:12If you switch between torch types, this covers both with one tool.
02:16So that's the list, cheapest, straightest, most adjustable, the backup, and the one that does both torch types.
