them not to watch the arc nor expose themselves to the arc rays or to hot spatter or metal. FUMES AND GASES can be dangerous Plasma cutting may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases. When cutting, keep your head out of the fume. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from the breathing zone. In confined spaces or in some circumstances, outdoors, a respirator may be required.
Never allow any electrically “hot” parts to touch a cylinder. Keep your head and face away from the cylinder valve outlet when opening the cylinder valve. Valve protection caps should always be in place and hand tight except when the cylinder is in use or connected for use. ELECTRICALLY POWERED EQUIPMENT can be dangerous Turn off input power using the disconnect switch at the fuse box before working on the equipment.

Always wear dry insulating gloves.
2. Direct interference radiated from the plasma cutting leads. 3. Direct interference radiated from feedback into the power lines. 4. Interference from re-radiation of “pickup” by ungrounded metallic objects. Keeping these contributing factors in mind, installing equipment per the following instructions should minimize problems.
INPUT CONNECTIONS ELECTRIC SHOCK can be fatal Have a qualified electrician install and service this equipment. Turn the input power OFF and unplug the machine from the receptacle before working on this equipment. Allow machine to sit for 5 minutes minimum to allow the power capacitors to discharge before working inside this equipment. Do not touch electrically hot parts.

GAS CONNECTION Obtain the necessary air. Connect the cylinder of compressed air or air compressor with a pressure regulator and flow gage.
OUTPUT CONNECTION (Figure A.3) The plasma cutting torch and ground cable are supplied with the plasma cutter. To connect the cables, turn the Power Switch “OFF”. 1. Plug the major power connector (the wider wire) from the torch cable to the “Cutting Torch” output terminal (5)1. Turn it clockwise using the plastic safe protector until snug, do not over tighten. 2. Plug the 2-prong connector from the torch cable into the 2-pin socket marked as “Switch” (7). Turn the outer metal shell clockwise to tighten.
