An ArcWriter is a dual gas, variable output power, plasma marking, scoring and punching system designed to leave temporary or permanent identification marks on metal surfaces. This is very often a sep [..]

This is the amount of movement the machine can make without moving the motor. Provision is made on all Esprit machines to reduce this to a minimum by the use of very low or virtually zero backlash gea [..]

This is a build-up of waste material, removed during the cutting process, which sticks to the underside of the profile. This is preventable by correctly setting the cutting process variables.

This refers to the percentage of time in any ten minutes that the plasma arc can be cutting. It is usually 100% on mechanised plasma cutting systems.

The electrode is used to start the plasma cutting arc. A high frequency low-amperage current is passed between the electrode and the nozzle, which is seen as the pilot arc. The electrode has a slug of [..]

The nozzle has two purposes. The pilot arc is struck between the electrode and the nozzle, the nozzle being connected to the other side of the High-frequency generator. Once the pilot arc has struck a [..]

One common description of plasma is to describe it as the fourth state of matter. We normally think of the three states of matter as solid, liquid and gas. For a common element such as water, these st [..]

The shield is a copper item that is screwed on to the front of the torch when all the other components have been put in. It is designed to protect the nozzle from splatter produced when piercing. The [..]
