A few comments hopefully helpful or of interest re: several of the products mentioned.
The Meco Midget preforms O.K. on ‘residential’ natural gas pressure using Paige Tools Tips. The Little Torch does not. It needs a ‘little’ more pressure. A NG Booster, like the G-TEC, enables Torches to produce physically larger flames with higher BTU output. Another option for greater heat output, without a pressure booster, is using propane… also a clean fuel gas easy to work with.
Residential NG delivery pressure is commonly expressed in water column inches. About 7 water column inches is typical of the delivery pressure to residential customers. Equal to around ¼ PSI. Very low pressure! The Hoke Torch runs ‘O.K.’ on that pressure but its small flames, using ‘stock’ Hoke Tips, make it better for gold working than for silver. As mentioned the Meco with Paige Tips can also operate at that low pressure butt the Little Torch needs somewhat higher pressure. Changing to Paige Tips with either NG or Propane and the Meco, Little Torch & Hoke ‘really’ preform!
Compressed ‘air’ is not an option with these Torches because of their internal designs, made to work ‘only’ with oxygen and ones choice of fuel gas. Tip design is equally important for the best flame control and highest BTU output. Using a multi-port Tip allows NG & propane flames to burn correctly. With adequate gas pressure these Torches are ideal for jewelry making fabrication, general soldering and annealing needs.
Each Torch has it’s advocates and benefits. The same goes for fuel gas choices. Whichever combination you choose (Torch + fuel gas) be sure to match the Tip design to the fuel gas. Your Torch work will be easier, flame heat (BTU output) greater and flame control much smoother.
