As a convenience, the torch can be set up with two cutting combinations, either drag or non-shielded cutting. The torch comes standard with drag cutting.

.Maximum performance on thicker materials can be obtained by using non-shielded cutting with a 1/16 - 1/8 in (1.6 - 3.2 mm) standoff.

Drag Cutting

Use retaining cup (197 567) and drag shield (196 929) to obtain a 1/16 in (1.6 mm) standoff automatically. This combination is designed to allow dragging the torch directly on the workpiece.

Use shields for ease of use when cutting with a template, or when drag cutting is preferred.

Non-Shielded Cutting

196 926

Use retaining cup (196 928) and hold a 1/16-1/8 in (1.6-3.2 mm) standoff between the workpiece and cutting tip.

Use non-shielded when visually following a line.
