Multiplaz 3500 Portable Plasma System Operating Manual Please read this manual prior to operating the system and keep it for future reference. ©2007-2010 “MULTIPLAZ TECHNOLOGY (SHENZHEN) CO., LTD.
Legend - “Caution” - “Prohibited” International Standards Certificate of Conformity U1 2792095 01 Product is "UL Listed" as Welding Machine (3NX1) Manufacturer: Multiplaz TECHNOLOGY (SHENZHEN) CO., LTD Address: 5/F, Building C3, Heng Feng Industrial Park, He Zhou, Bao An, ShenZhen, China, 518102 Product: Multiplaz-3500 This is to certify that the above product is compliant with the following directives and standards: Low Voltage Directive: 2006/95/EC Arc Welding Equipment - Part 1: Welding Power Sources.
Thicker sheets should be cut using MODE II. Set the MODE I current indicator to position 6 and voltage to 210-220 V. Then activate MODE II. Direct arc of MODE II appears automatically as the torch nozzle is brought 2-3 mm (0.08-0.12 inches) from the surface of the workpiece. Select rate of torch translation along cut such that the arc stays on the workpiece material and molten metal is removed.
44 When cutting, keep in mind that the unit’s plasma jet is supposed to remove molten metal through the cut. This requires cuts to be initiated at the workpiece edge. If this should prove impossible from the process standpoint, a hole must be drilled to be used for cut initiation. For thin sheet metal, “punch-through” cutting may be used where the initial hole is obtained by burning through the metal.

In addition, safety is assured by a grounding circuit included in system design. Per the design requirements, the grounding circuit has to be connected to an outside ground. The manufacturer is not responsible for any damage resulting from failure to connect ground.

Process Attachment 3 Cathode Metal Housing Evaporator Spring Quartz Tube Plastic Housing The Multiplaz-3500 portable plasma system is a source of low-temperature plasma obtained by heating to ionization temperature vapors of a process fluid placed in the torch prior to operations.
7.16. Repair, Service, and Support Repair and maintenance are performed by authorized dealers. 3.2 Torch Operating Principle Once the torch is filled with the proper fluid, the power supply is connected, and voltage is applied to the cathode (the ON button is pressed), the operator can cause the torch to produce an arc by pressing the start button briefly. This results in the cathode shorting to the torch nozzle. As the start button is released, an electric arc is produced between the cathode and nozzle.
7.8. Stainless steel not welding Use an ethyl alcohol concentration of 55% to 60% and appropriate filler wire (see Process Attachment) . For thickness of under 2.5 mm (0,1 inch) use brazing (brass or silver-based solder). The power supply comprises: Voltage Display MODE I Current Indicator MODE II Current Indicator 7.9. Process fluid leak from under the cap Cap not tight enough - tighten cap. “OFF” Button (red) 7.10.
7. Questions and Answers Troubleshooting Techniques 3.4 Controls Operating mode is selected by adjusting current and voltage values. Caution! Do not attempt repairs if the failure is not described in this section. Instead, contact an authorized dealer for assistance To increase or decrease current use the 5or6buttons respectively on the current control panel. 7.1 Current indicator fails to be set in position 5-6. Supply network voltage is 100-120V. Use a 208-240V power supply.
6.6 Torch Assembly 4. Cutting - Use distilled water Study the Safety section and comply with its requirements. 4.1 Connection of Power Supply - Connect power supply power cable to wall receptacle. - Verify that voltage display and “OFF” LED are illuminated. - Verify that fans are on. 1 2 4 5 7 8 3 Caution! Voltage display may show a value of up to 5 volts if the “OFF” LED is illuminated. 4.2 Torch Connection to Power Supply - Take cutting torch with green mark.
6.2 Torch Disassembly Tips and Techniques А) Nozzle is jammed in cap: press it out with plunger. B) Nozzle is “stuck” to evaporator: remove evaporator with nozzle, place cap over nozzle such that cap and nozzle back edges align, and “break” nozzle off using cap without exerting force. C) Cathode is heavily melted: remove evaporator and cathode holder from torch (after Section 6.1 Step 8).
6.1 Torch Disassembly 4.6 Cutting Procedure 4.6.1 MODE I Cutting MODE I cutting produces the narrowest cut. Cut at a constant rate. Maintain a clearance of between 1 and 3 mm (between 0.04 and 0,12 inches) between nozzle and workpiece (nozzle contact to workpiece is allowed). To achieve maximum cutting rate, use left 5 button to set current indicator on MODE I panel to position 6 (particulars on selecting current settings are given in Section 7.
5.9 Refilling Torch To refill torch with water/ethanol mixture, perform the steps described in Section 5.8 and 5.2. Automatic torch refilling(Section 4.8.2) with water/ethanol mixture is not possible. Caution! - Cool in WATER ONLY. Cooling in water/ethanol mixture could cause a fire. 5.10 After Operation - Press ”OFF” button on power supply. - Be sure that ”OFF” LED is illuminated. - Disconnect torch cable connector from power supply outlet connector (to select cutting mode proceed to Section 4.2).
4.8 Refilling Torch Torch may be refilled in two ways 4.8.1 Forced refilling - Fill the torch as written in Section 4.4 4.8.2 Automatic Filling - Shut torch down per Section 4.7. - Dip nozzle in 3-5 cm (1-2 inches) of water (free of sediment) for 2 - 3 minutes (see figure). This method can only be used immediately following torch shutdown because of the suction effect. - Once filled, wipe torch dry. Caution! - Do not allow unprotected areas of your body to come into contact with hot torch surfaces.
5.6.2 MODE II Welding 5. Welding, Brazing, Braze Welding, and Soldering Welding in this mode is similar to argon arc welding. Study the Safety section and comply with its requirements. 5.1 Connection of Power Supply - Connect power supply power cable to wall receptacle. - Verify that voltage display and “OFF” LED are illuminated. - Verify that fans are on.
- Within 5 seconds after pressing “ON” button, fully depress start button (when cathode comes into contact with nozzle, the voltage will drop to 0 - 5 V), and release it slowly (voltage in initialized arc is between 20 and 80 V). - Several seconds later a jet is supposed to appear from torch nozzle, while voltage will increase to 80 -160 V. - Set operating voltage to 160-170 V by turning start button clockwise. - Connect filler holder to grounding connector on power supply rear panel. 5.
