How to Cut Steel With Inductance

Using a combination of compressed air and electric arc, induction cutters or plasma cutters as they are more commonly known, is one of the most effective methods for cutting steel. The superheated gas creates a high-pressure plasma stream which cuts through steel better than traditional methods, such as oxyacetylene cutting. Although quick and effective, plasma cutting can also be quite dangerous and can quickly result in damage to the steel or injury to the plasma cutter operator.

Instructions

- 1
  Clear away any flammable materials from the area where you will be induction-cutting your steel.
- 2
  Clamp the steel piece to two sturdy, metal worktables using C-clamps. The area you intend to cut should be suspended between the two tables to allow the plasma cutter to penetrate the surface without damaging the table below.
- 3
  Set the plasma cutter's "Test Gas/Cutting" switch to "Cutting."
- 4
  Set the amperage of the plasma cutter, using the "Current" dial. The thicker the piece of steel, the higher amperage you will need to effectively make the cut. Consult the user's manual for your cutter to determine the appropriate amperage for your job.
- 5
  Switch the plasma cutter to "On."
- 6
  Grasp the torch of the plasma cutter in your dominant hand and hold the nib just above the workpiece. Check that your other hand is well away from the cutting point.
- 7
  Squeeze the trigger to begin cutting. Slowly pull the plasma torch back toward yourself, taking care to keep the tip angled away from your body.
- 8
  Once the cut is complete, switch the plasma cutter to "Off."
