Always clean and dry the areas first. Fumes and Gases Hazards 1. Welding and cutting fumes and gases may be hazardous if inhaled for long periods of time. 2. Install a natural or forced-air ventilation system in the work area. If the ventilation system is inadequate, use an air respirator. 3. Use a forced-air ventilation system when welding or cutting lead, beryllium, cadmium, zinc, zinc-coated or painted materials. Always wear a protective breathing mask. 4. When welding or cutting in small areas, the operator should be externally accompanied by another person to observe accident prevention procedures. 5. Do not perform welding operations near chlorinated hydrocarbon vapors produced by degreasing or painting; the heat generated by arc rays can react to form phosgene, a highly toxic gas. 6. Irritation of the eyes, nose, and throat are symptoms of inadequate ventilation. Take immediate steps to improve ventilation. Do not continue operations if symptoms persist. SKU 45949 Page 5 Transporting the Plasma Cutter 1. When moving the Plasma Cutter, the power must be shut off and disconnected. 2. Pull the Plasma Cutter by its handle and roll on its wheels. 3. Do not drag, pull, or lift the Plasma Cutter by it’s cables. High Frequency Radiation 1. When cutting or welding, be aware that high frequency radiation may be produced which can interfere with radio navigation, safety services, computers, and communications equipment. Before operations, have a qualified electronics technician check out that possibility. 2. Keep high frequency source doors and panels tightly shut. Keep spark gaps at the correct settings. Use proper grounding and shielding to minimize the possibility of interference. Keep all cables close together and close to the ground. Locate the welding or cutting operation as far as possible from sensitive electronic equipment; or have the electronic equipment shut down temporarily. Electrical Shock Hazard 1. Electric shock could be fatal. Never touch exposed electrical parts. 2. Switch off and disconnect the power source before installing or opening the Plasma Cutter. 3. Installation must be performed by a qualified technician. 4. Installation procedures must comply with the National Electric Code, and all other relevant regulations. Unpacking When unpacking, check to make sure the following parts are included. 3 - Electrodes (not shown) 3 - Nozzles (not shown) If any parts are missing or broken, please call Harbor Freight Tools at the number on the cover of this manual as soon as possible. SKU 45949 Page 6 Assembly 1. Assembly the platform stand and attach the wheels using the supplied hardware. 2. Place the Plasma Cutter on the Platform Stand and secure with the supplied hardware. 3. Attach the Pull Handle to the Plasma Cutter with the supplied hardware. 4. Install a 3-prong, 220 VAC power connector with at least a 35 amp capacity. This should only be done by a licensed electrician. Operation WARNING: This product, when used for welding and similar applications, produces chemicals known to the State of California to cause cancer and birth defects (or other reproductive harm).

The air supply should have an in-line moisture filter. 2. Check the Plasma Torch. Replace or clean the nozzle and electrode if worn or dirty. 3. Clamp the Plasma Cutter Ground Cable Clamp to the bare metal workpiece. 4. With the On/Off switch set to “O”, plug the power cord into the 220 VAC (35 amp capacity) electrical outlet. 5. Place your protective clothing, gloves, and welding helmet. 6. While holding the Torch handle away from the workpiece, set the On/Off switch to 20A or 35A depending on the hardness of the metal being cut. It is recommended to do a test cut on a piece of scrap metal of the same type as the work piece to determine the correct amperage and air pressure for a clean cut. SKU 45949 Page 7 7. Adjust the air pressure from the Control Filter Knob on the back panel. Caution: Verify that no wires, cables, or other obstructions are below the cutting area. 8. Place the Torch Head on the metal to be cut and press the Start button on the Torch handle. Start to cut slowly, then increase the speed to obtain the desired cut quality. Regulate the speed to obtain a good cut. See illustration “A” below. Air plasma will create a straight arc with stainless steel or aluminum, or a 5” arc with softer steel. The arc varies depending on speed, material, and thickness. A B In some cutting operations, it may be necessary to start the cut from a point away from the edge. See illustration “B” above. The backfire from this operation could shorten the l...
