Hand Torch Cutting Technique - Hypertherm POWERMAX1250 Operator's Manual

OPERATION

Hand torch cutting technique

Firing the torch unnecessarily reduces nozzle and electrode life.
When cutting, make sure that sparks are exiting from
the bottom of the workpiece.
If sparks are spraying up from the workpiece, you are
moving the torch too fast, or without sufficient power.
Position the torch nozzle at a vertical position and watch
the arc as it cuts along the line.
Unshielded consumables. Maintain an approximate
1/8 inch (3 mm) torch-to-work distance.
Shielded consumables. Do not push down on the
torch when cutting. Lightly drag the torch across the
workpiece to maintain a steady cut.
• Pulling the torch through the cut is easier than pushing it.
• To cut thin material, reduce the amps until you get the best quality cut.
• For straight-line cuts, use a straight edge as a guide. To cut circles, use a template or
a Hypertherm circle cut guide, part number 027668.
