Question about torch + hoses
I have a question. I'm a noob here and about to start setting up my shop but first I need to make sure I have the right equipment. I have a national 8m which I plan to run with an sm-21 tip. I bought the Devardi Glass Lampworking Oxygen/propane Torch regulator and hose kit with 2 inch gauges off ebay. There was also an option to buy the same thing but with 3 inch gauges. I admit I'm not really sure what the difference is or if you need one or the other for the specific torch I got. Can anyone help me with this? Thanks!
