Tweco Torch Data AutoCut User Manual

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.

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

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 perfor­mance 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 gauge ball.

Manual 0-4825 Rev. AK 8-1 TORCH DATA for AutoCut Basic

Ohmic Sensing

Ohmic sensing is not recommended with water shield. Water on the plate interferes electrically with the ohmic
sensing circuit.

Direction of Cut

The plasma gas stream swirls as it leaves the torch to maintain a stable arc column. This swirl effect results in one
side of a cut being more square than the other. Viewed along the direction of travel, the right side of the cut is more
square than the left.

Side Characteristics Of Cut

To make a square - edged cut along an inside diameter of a circle, move the torch counterclockwise around the circle.
To keep the square edge along an outside diameter cut, move the torch in a clockwise direction.

Underwater Cutting

Cutting on a water table either underwater or with the water touching the plate or with a water muffler system is not
recommended. If a water table is used the water level must be a minimum of 4 inches / 100 mm from the bottom of the
plate. Failure to follow this recommendation could result in poor cut quality and short consumable parts life.
