Like the results of NG in place of propane with a Scorpion. When working with NS white the glass has less of a tendency to boil. Seems there is more control IMO. The flame is harder to see (diddy + welder's shade 3) as it burns very clean. The plus part is that the number of needed concentrators dropped from three to two saving on power costs.

For propane a regulator is a must to covert the 80 - 125 psi to a working pressure of say 5 psi for a GTT torch. For NG the standard pressure is 11 WC or .4 psi. The pressure delivered to the NG regulator supplied by the gas company, in my case, is 60 psi line pressure. Some companies will allow for a pressure greater than 11 WC in residential settings. Others will not.

There are NG compressors for torches to boost NG from 11 WC to 25 psi with different cf/hr capacities. Costs start out at $1,100 plus shipping. Power requirements are 120V at 15 amps.
