Let me say this.
Razorweld and Langmuir has said that you can use Hypertherm consumables on the X45/HYP45/Flame torch.
But Razorweld nor Langmuir sells Hypertherm consumables for their customers to buy.
I do not recommend using Hypertherm consumables and Hypertherm does not recommend it.
Best thing I can tell you is call Hypertherm (800) 643-9878 and ask them what they think about this and their recommendations.
Now that being said, anyone that wants to try it is more then welcome to do so as its their plasma cutter and torch. Its also their money to spend on a new plasma cutter and or torch if it causes damage like it has for others on this forum.
