I have sold thoudsands of ESAB Torch Kits in my distributor days and yes, I agree that the Purox line is among the best out there. I have sold every style of TrimLine down to the 250 series and ESAB would be my choice over Smith or Harris. Actually I would choose Harris over Smith too. The reason is if Smith were so good, Someone would be copying it by now. Burnout wise, The new Victor Edge Rags can not burn out. Look them up. Also I am not by any means bashing Smith. A very good friend of mine is a Smith Rep and that is where I get my info. As for My Alaska comment, Yes I work with EXXON, SHELL and BP quarterly and spend time in -60 to -80 actual temps. They choose Victor Edge Regs and Torches. Lincoln Welders all types, Tweco Mig Guns, Thermal Arc, OTC and Fronius for Twin Pulse Aluminum Welding, TD Plasma, Jackson Hoods and a few Speed Glass, Stoody, MG and Lincoln hard surface wire, Turbo torch and Harris Welco for all Soldering and Brazing and that's it. It seems like what ever Brand someone owns, They brag it up to be the best. The Fact is, There is no real Junk out there or it wouldn't be out there. From a Salesman perspective The problem is it all lasts too long. If you sell a Torch set ( any brand ) It will last 20-30 years and for a few hundred bucks it lasts too long. Aside from the Battery Charger Names, The Mig, Tig , Stick and Plasma units will last too long too.
