## Questions & Answers

**Q: Will this fit on the lotos LT5000D plasma cutter?**
A: Yes, if the lotos LT5000D working with PT-31 or LG-40 torch.

**Q: Will this fit a cutmaster 42?**
A: Not sure if it will fit cutmaster42 due to the tip length. The roller has a taper where the colet sets with 2 allen head set screws. It's a nice item to have for the price compared to others and I'm pretty sure you could make it work.  Hope this helps.

**Q: Can this be used to cut straight lines**
A: Yes I do it all the time take the rod off and use a strait edge for a guide and it works great I love mine use it all of the time.

**Q: Will these work on the thermal dynamics sl60i plasma cutters? 
No they are way way to small.**
A: No, it can't.
