INTRODUCTION This manual contains descriptions, operating instructions and basic maintenance procedures for the Plasma 30,40,50,machines. Read this manual thoroughly. A complete understanding of the characteristics and capabilities of this equipment will assure the dependable operation for which it was designed. WARNING _ Warning: Protect yourself and others from injury — read and follow these precautions. _ Only qualified persons should install, operate, maintain, and repair this unit.
_ Do not touch live electrical parts. _ Wear dry, hole-free insulating gloves and body protection. _ Insulate yourself from work and ground using dry insulating mats or covers big enough to prevent any physical contact with the work or ground. _ Do not touch torch parts if in contact with the work or ground. _ Turn off power before checking, cleaning, or changing torch parts. _ Disconnect input power before installing or servicing this equipment. Lockout/tagout input power according to OSHA CFR 1910.
_ Wear approved face shield or safety goggles with side shields. _ Wear proper body protection to protect skin. _ Wear flame-resistant ear plugs or ear muffs to prevent sparks from entering ears. Arc rays from the cutting process produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin. ARC RAYS can burn eyes and skin. _ Wear face protection (helmet or shield) with a proper shade of filter lenses to protect your face and eyes when cutting or watching. ANSI Z49.
the radius of the plasma beam. NOTE! This machine is designed to use only compressed air as the “gas”. B. Voltage Regulation The Automatic Voltage Compensation circuit prevents voltage load from exceeding maximum in accordance with the main technical data sheet and shortening the life of the machine. C. Thermal Protection The thermal protection circuits will engage if unit exceeds duty cycle. This will cause the machine to stop working. The indicator will be lit on the front of the machine.

Note: The input current required to produce the INSTALLATION A. Unpacking Unpack all items and verify that all items have been received according to the packing list enclosed. B. Operating Environment Make sure working area is well ventilated. The unit is cooled by an axialflow fan which provides airflow through the back panel over the electronics and out the machine cover vents.
Position yourself to where you can read the air pressure. Press the torch switch (air will exhaust from torch, adjust the air regulator to read approximately 60 to 70 pounds (PSI) and release torch switch. sheet metal to reduce the chance of splatter-back tip damage. Note: The Air pressure has a generally acceptable range of 50 to 80 PSI. You may experiment as desired… but be careful not to lower the pressure too much as consumable damage will occur. For piercing, position the tip approximately 1/8" (3.
speed of cut toward minimizing dross buildup on underside of cut. Experiment with adjusting current and speed to minimize dross. For more specific issues regarding quality of cuts and general operation, go to the Troubleshooting section of this manual. MAINTENANCE A worn Tip/Nozzle is indicated by an elongated or oversized orifice. The face of the electrode should not be recessed more than 1/8”. Replace if worn beyond this point. If the Shield Cup does not go on easily, check the threads. 2.
Arc stops while cutting Cutting speed too slow or Current to high. Increase speed and/or reduce current until dross is reduced to minimum. Worn torch parts Cutting speed too slow Inspect and repair or replace worn parts.
