The setting you need to adjust is basically your Kerf Compensation. This is controlled in the Torchmate CAD software in your toolpathing parameters. On the basic cut tab, there is a tool selection. In this tool library you can add or update existing tools with different Kerf widths. Kerf is the amount of material your torch is removing, and varies with speed, height, material thickness, and amperage. Typically to measure this you would cut a straight line with all of the settings mentioned set, and then take a pair of calipers and measure the kerf width of the cut. You can then define this width in your tool library and assign the correct tool.
