5 section 1 safety precautions 1.0 Safety Precautions Users of ESAB welding and plasma cutting equipment have the ultimate responsibility for ensuring that anyone who works on or near the equipment observes all the relevant safety precautions. Safety precautions must meet the requirements that apply to this type of welding or plasma cutting equipment. The following recommendations should be observed in addition to the standard regulations that apply to the workplace. All work must be carried out by trained personnel well acquainted with the operation of the welding or plasma cutting equipment. Incorrect operation of the equipment may lead to hazardous situations which can result in injury to the operator and damage to the equipment. 1. Anyone who uses welding or plasma cutting equipment must be familiar with: - its operation - location of emergency stops - its function - relevant safety precautions - welding and / or plasma cutting 2. The operator must ensure that: - no unauthorized person stationed within the working area of the equipment when it is started up. - no one is unprotected when the arc is struck. 3. The workplace must: - be suitable for the purpose - be free from drafts 4. Personal safety equipment: - Always wear recommended personal safety equipment, such as safety glasses, flame proof clothing, safety gloves. - Do not wear loose fitting items, such as scarves, bracelets, rings, etc., which could become trapped or cause burns. 5. General precautions: - Make sure the return cable is connected securely. - Work on high voltage equipment may only be carried out by a qualified electrician. - Appropriate fire extinquishing equipment must be clearly marked and close at hand. - Lubrication and maintenance must not be carried out on the equipment during operation. 117

6 section 1 safety precautions WARNING WELDING AND PLASMA CUTTING CAN BE INJURIOUS TO YOURSELF AND OTHERS. TAKE PRECAUTIONS WHEN WELDING OR CUTTING. ASK FOR YOUR EMPLOYER S SAFETY PRACTICES WHICH SHOULD BE BASED ON MANUFACTURERS HAZARD DATA. ELECTRIC SHOCK - Can kill. - Install and earth (ground) the welding or plasma cutting unit in accordance with applicable standards. - Do not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing. - Insulate yourself from earth and the workpiece. - Ensure your working stance is safe. FUMES AND GASES - Can be dangerous to health. - Keep your head out of the fumes. - Use ventilation, extraction at the arc, or both, to take fumes and gases away from your breathing zone and the general area. ARC RAYS - Can injure eyes and burn skin. - Protect your eyes and body. Use the correct welding / plasma cutting screen and filter lens and wear protective clothing. - Protect bystanders with suitable screens or curtains. FIRE HAZARD - Sparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby. NOISE - Excessive noise can damage hearing. - Protect your ears. Use earmuffs or other hearing protection. - Warn bystanders of the risk. MALFUNCTION - Call for expert assistance in the event of malfunction. READ AND UNDERSTAND THE INSTRUCTION MANUAL BEFORE INSTALLING OR OPERATING. PROTECT YOURSELF AND OTHERS! 118

7 section 2 DEscription 2.0 Description 2.1 System Introduction The m3 Plasma System is a streamlined, high performance-cutting package designed for use exclusively with the ESAB CNC. This advanced technology integrates gas and water control into the machine CNC. Using a system of electronic valves driven by CNC outputs, this system: dramatically reduces the amount of Plasma Gas hardware necessary to control the plasma torch. reduced purge time/increased part throughput. simplified operation with gas and water flow rates are controlled by the ESAB CNC process parameter screen. allows for programmed/automated control of fluid and water flow rates using SDP Files (SchneidDaten- Paket = Cutting Data Package, see Vision control and programming manuals for details on SDP Files. Data used to generate SDP files can be found in your model specific torch manual.) SDP files can also be referred to as TDF files (Technology Data Files). to be used with the PT-36 cutting torch. Plasma Gas Box Shield Gas Box 2.2 m3 Plasma System Plasma Gas Box, Shield Gas Box and PT-36 The complete m3 cutting system requires a variety of components.

31 section 4 operation 4.0 Operation 4.1 Plasma Gas Box Operation A major advantage of the m3 Plasma System Plasma Gas Box is that operating parameters are managed by the machine CNC. There are no operating procedures necessary with the m3 Plasma System Plasma Gas Box. Management is accomplished either with manual inputs on the Vision cutting parameter screen or using the ESAB system of Process Parameter Files. Note: Process Parameter Files (known by the acronyms SDP or TDF) are files stored in the machine control memory containing all necessary information for cutting a thickness and a material type. It is specific to material, thickness, torch model, gas and material type. The information used to create the files can be found in your torch manual. Refer to ESAB CNC Part Programming manual for more detail on the creation and use of parameter files. notice See CUT DATA MANUAL, P/N for cutting parameter settings for using the m3 Plasma System Plasma Gas Box. 4.2 Plasma Gas Box Pressure Gauges Pressure gauges display actual pressure to the torch. They provide visual feedback to the operator, and can be helpful in spotting torch problems. Start Gas (PG1) Note: PG1 & PG2 are referred to as Start & Cut gas most of the time. Certain cutting conditions require PG1 conditions only. Cut Gas (PG2) 143

32 section 4 operation 4.3 Plasma Gas Box Pressure Switches Pressure switches monitor line pressure and provide inputs to the CNC. If the pressure drops below 50 psi, the CNC can shut the process down. Switches are in-line between the solenoid and the proportional valve for shield gas 1 & 2, start gas and cut gas.
