8. TORCH OPERATION

Torch Parts Selection

The application will determine which torch parts must be used. Refer to the cut charts for the proper torch parts to

install for a selected application.

CAUTION

Do not interchange parts. Make sure all torch parts correspond with the

plasma and shield gases in use for the application.

Pre-Setting Power Supply Controls

Set the Power Supply controls prior to operating the system as described in the power supply Operating Manual.

Refer to the cutting charts for the proper cutting parameters for the application.

Recommended Cutting Speeds

Cutting speed depends on material and thickness. The following factors may affect system performance:

• Torch parts wear; gas quality and mass flow / pressure (mass flow); operator experience; torch standoff

height; proper work cable connection; alloying contents of material; cutting table capabilities & accuracy.

NOTE

This information represents realistic expectations using recommended

practices and well-maintained systems. Actual speeds may vary from

those shown in the charts depending on the alloy content of the selected

material. Voltage ratings may vary depending on the CNC, cutting table,

or height controller.

For complete cutting speed chart data refer to the following pages.

Consumables Notes

Always assemble the consumable parts properly. Improper assembly may damage the parts or the torch head.

Ensure that parts are seated together correctly.

Always check the shield gas distributor for charring when changing parts. Do not use the distributor if it is charred.

Replace the shield gas distributor regularly to ensure proper performance.

Operational Notes

Always purge the torch after changing consumables or if the power supply has been shut off. The power supply's

built-in purge function may not be enough to properly purge the torch. Manually flow gas with the 'Test Cut Flow' and

'Test Pre-Flow' functions to help remove any remaining coolant from the lines.

Slightly increasing the preflow pressure may increase piercing ability on thicker materials. However, increasing the

preflow pressure too much may affect plasma starting reliability (misfiring).

Decreasing preflow pressure may improve piloting. Preflow pressure can be reduced without affecting cut perfor-

mance as long as the pilot arc still transfers to the plate well. Decreasing preflow pressure too much will affect the

ability to transfer the arc to the plate and may cause damage to the tip.

Notes on Chart Measurements

Pressure measurements in the charts are in psi(g), not psi(a). 0 psi(g) = 14.7 psi(a) (1 atmosphere).

Ball settings are at the center of the guage ball.
