A lot of people like to use the PTM 60 torch on the 82i because they can get finer cutting tips 20,30 and 40 amp. The PTM 80 consumables start at 50 amp and that don’t work that well on 20 gauge metal cutting signs.
Note: Don’t get confused here. Tecmo makes the PT torch’s. Innotec makes the IPT torchs. But there is also the Chinese copys calling their torch’s PT and IPT.
