
Do the following to prevent the loss of a transferred plasma arc:

Complete every cut with the plasma arc still attached to the workpiece.

Decrease the cutting speed when the end of the cut is near.
Piercing guidelines
Piercing goes through the full thickness of the workpiece. Piercing is also typically the first action
involved in cutting a part.

Starting at the edge of the workpiece is permitted if the arc makes contact
with the workpiece when started.
You can keep unwanted results to a minimum, increase the number of pierces, and get maximum
cartridge life when you use the pierce and cut height settings that Hypertherm recommends in the
cut charts. Refer to the
Powermax65/85/105 SYNC Cut Charts Guide (810500MU) and the
following:

Pierce delay: Pierce delay is the length of time that the torch stays at the specified pierce
height before the torch starts to move for cutting. The pierce delay must be long enough that
the arc can pierce the material before the torch moves, but not so long that the pierce hole
enlarges and causes the arc to “wander” or extinguish before the torch starts to move.
Pierce delay times given in the cut charts use average delay times throughout the life of the
cartridges. If necessary, as the cartridge wears, increase the pierce delay time.

Pierce height: Pierce height is the distance between the torch and the workpiece that is
necessary to initially pierce the workpiece before beginning to cut. For the
Powermax65/85/105 SYNC, the pierce height is generally between 150% and 400% of the
cut height. Refer to the
Powermax65/85/105 SYNC Cut Charts Guide (810500MU) for
specific values.

Pierce maximum thickness: When piercing materials close to the maximum thickness for a
specific process, think about the following important factors:

Use a lead-in distance approximately equal to the thickness of the material being
pierced. For example, a 20 mm (3/4 inch) lead-in is necessary for 20 mm (3/4 inch)
material.

To prevent damage to the cartridge from the collection of molten material caused by the
pierce, do not let the torch descend to cut height until it is away from the puddle of
molten material.
