RIVERWELD L-TEC PT-31 JG-40 WSD-LG40 PT-31 Plasma Cutter cutting Torch Attachments Circle Roller Guide Wheel Compass

Good product, reasonably priced!

As stated, It fits my PT-31 torch perfectly. After trying this circle cutter the cost will be forgotten and you wonder why you never purchased this long ago. Makes the most perfect circles. But I would recommend practicing on a piece of scrap to get used to it.

This is an excellent quality product. However, it has a center boss that is rather small in diameter and it did not fit my Lotos LTP5000's torch. The ceramic nozzle on my torch (LTP5000) is about 1.040" diameter, which is slightly bigger diameter than the inside of the Mohoo's collar, which is about 0.923" diameter, so it won't go in. But my project won't wait, and the Mohoo took quite awhile to get here, so I don't have time to order a different one. I took off the circlip that holds the collar together with the wheel base, and cut off the top part of the center collar and fabricated a larger collar to press onto it so that I could fit my torch into it... which worked fine, but the cut standoff height was now way too high and there is no way to get it lower... so that meant I also had to fabricate new wheels to go onto it (smaller diameter ones) to drop the cut standoff height to around .100"...this made it work just fine, but it was a lot of work. I see a lot of people also order the Panasonic wheel assembly to go with this, as that one has a much wider center and the wheel height is adjustable for a variable standoff. I think I will just order the Panasonic too, in case I have to adjust my standoff height (it works great now, but I haven't had it long enough to know if I need a closer standoff height for thicker stuff).

You really have to mess with adjusting it quite a bit. Also, it’s not really designed to fit on a small plasma tip so bear that in mind. I ended up just leaving one of the ceramic heads in it and screwing the whole thing onto the gun as I need it.

It is what I was looking for

Wanted to post that it works well with my Herocut Plasma Cutter, 45Amp Plasma Cutting Machine, Dual Voltage 110V/220V. Needed to cut some 6" and 4" circles in 1/4" plate and this made the work easy. I would not want to cut those without guide as my freehand cutting is not that accurate.

Giving it a 5 star but I haven't used it yet. The 5 star is bcuz this is the most well built free hand roller. I've tried a handful of others and not one comes close. It is very heavy for what it is. I have dry run it and it's going to work well.

Well made. However it doesn’t fit the more common plasma cutter Cutmaster 52. What the heck, can’t the manufacturers get a clue. This outfit is clueless. Wish they had a listing of what this would fit. Something so simple.
