For additional safety precautions, process instructions, and system troubleshooting; refer to the appropriate instruction manual for your Plasma Arc Cutting Package.
Torch Guide Kit Permits cutting accurate circles from 45mm (1.7") to 1050mm (41.3") in diameter with the PT-31XL or PT-31XLPC. The attach- ment includes a head and radius bar assembly, center-point / adaptor, and dual swivel castor assembly. Cuts can be made inside or outside the circle.
SECTION 2 DESCRIPTION 2.4 Technical Data (required by CE) a. Process: Manual torch used for plasma arc cutting b. Method of guidance: Manual c. Voltage class: M (113v peak to 400v peak) Striking voltage: 8000 VAC Stabilizing voltage: 200 VDC d.
VOLTAGE IF THE TORCH SWITCH IS ACCIDENTALLY CLOSED WHEN THE SHIELD IS REMOVED. ALWAYS REPLACE TORCH WITH THE PROPER TORCH MANUFACTURED BY ESAB SINCE IT ALONE CONTAINS ESAB'S PATENTED SAFETY INTERLOCK. The gas flow check valve is part of the safety interlock and is permanently assembled in the torch head.
SECTION 3 INSTALLATION / OPERATION Disassembly of Torch - Removing Consumables To disassemble the front end, hold the torch with the shield in an upright position as shown in Figure 3- 2. This will prevent the nozzle, electrode, and swirl baffle from falling free when the shield is removed. If the torch is fixed and cannot be rotated upward, the alternate method of disassembly is to disassemble the electrode, swirl baffle and nozzle as above being careful not to damage them by letting them fall.
SECTION 4 MAINTENANCE Maintenance BEFORE ANY MAINTENANCE IS ATTEMPTED ON THIS TORCH, MAKE WARNING SURE THE POWER SWITCH ON THE CONSOLE IS IN THE "OFF" POSI TION AND THE PRIMARY INPUT IS DEENERGIZED. BE SURE TO TIGHTEN POWER CABLE CONNECTIONS SECURELY US ING 2 WRENCHES DURING REASSEMBLY.
