To determine the maximum rated cutting
thick ness of mild steel, follow the line from
the 10 IPM (inches per minute) point on
the cutting chart. The point at which this
line intersects the cutting curve determines
the maximum recommended production
cutting thickness of the unit.

Note: The rating is based on 10 IPM because this is
the minimum speed at which the operator achieves a
smooth, steady cut when using a hand-held torch.

Rated cut capacity is based on traveling
approximately 10 inches per minute to achieve
a steady, precise cut. This is the key rating that
should meet or exceed your typical cutting
thickness requirements.
