The Spartin is a bit of a plain Jane that will be tossed aside when you upgrade.
A National 3A with a 7 jet tip will give you lots of power. Will run on propane or natural gas very well. You can get the 6A a bench model thats the same thing. The advantage is when you buy a 3A it can be used as your hand torch when you upgrade to a big bench burner.

It will do small work and when you want an upgrade you can get a 31 jet tip , a $59 upgrade and make work like the big boys. I see Klines and recyclers made on the national.
Its an old school tried true and tested old torch still sold new today with lots of part available.
I got mine on E bay for $52 and machined my own tip buy you can buy tips.

This is my 3A on natural gas and oxygen concentrators.
I recommend this torch to anyone.

I have a lot nicer torches but the national is still a welcome addition to my shop. Its earned its place as a permanent item along with the expensive torches.
