B) Amperage, cutting tip diameter, and type of fuel gas
C) Material shape, arc length, and amperage
D) Type of fuel gas and material thickness, shape, and surface condition

Question

Quizplus · Accepted Answer

The amount of preheat flame required to make a cut is determined by the type of fuel gas and the material thickness, shape, and surface condition. The fuel gas is important because different gases have different heat outputs, and the material properties determine how much heat is required to make a clean cut. Material thickness, shape, and surface condition all affect the process as well, as thicker materials and complex shapes require more heat to make a clean cut.
