Which statement is true concerning torch tips for the oxyacetylene rig?

A 000 size tip is used for higher power.
A 000 size tip is smaller than a size 10 tip.
A 000 size tip is larger than a size 6 tip.
A 000 size tip is for cutting thicker metals.

The correct answer is: A 000 size tip is smaller than a size 10 tip.

A 000 size torch tip is smaller than a size 10 tip. In oxyacetylene welding and cutting, the size of the tip refers to the orifice size. The orifice size affects the flow rate of the gas and the size of the flame produced. Typically, the larger the number, the smaller the orifice size. In this case, a 000 size tip is smaller than a size 10 tip, making the statement true. Option A is incorrect because a 000 size tip actually has a smaller orifice size, which results in less power output compared to larger tips. Option C is incorrect because, as mentioned before, larger numbers correspond to smaller tip sizes. Option D is incorrect as well because cutting thicker metals usually requires larger tips with higher power output.
