The swapping part has been covered above and I also routinely use my hand torch for cutting down 4 x 10 sheets of steel.
I wanted to also say I have my cutter sitting on one of the Harbor Freight moving dollies at the end opposite my table controller. Between the long cable of the machine torch, the 20’ on my hand torch, and the rolling cutter, I never encounter issues getting where I need to be to cut down my steel.
