Pick the Hobart 770502 oxy-acetylene kit if...
You also weld, braze or heat steel, you cut thick sections, or you do not have the 120V power or clean shop air for a plasma cutter.
Pick the Hobart AirForce 12ci plasma cutter if...
You mostly cut sheet and plate, want clean edges with little cleanup, and prefer not to manage gas cylinders, flashback arrestors and refills.
Who should skip both
You only cut a few parts a year. A good angle grinder or reciprocating saw is cheaper. See plasma cutter vs angle grinder before you spend.
Where to buy
Frequently asked questions
Is a plasma cutter better than a torch for a home shop?
For cutting, usually yes: it is faster, cleaner and easier to learn. A torch still wins for heating, brazing and welding.
Do I need an air compressor for the Hobart 12ci?
No. The AirForce 12ci has a built-in compressor, so no external air is needed.
Is oxy-acetylene safe to use at home?
It is safe with training, check valves, flashback arrestors and good ventilation. Follow the manual and local rules for cylinder storage and transport.
Can a plasma cutter cut aluminum and stainless?
Plasma cuts any conductive metal; check Hobart cut ratings for each material and thickness.
