  • Page 7 Thank you for using Weldpro arc welding and cutting equipment. We ask you to work like a weld-pro and weld-pros weld and cut safely. Please read and comply with the sample safety procedures outlined in this guide and the equipment Owner's Manual.
  • Page 8 1. General Safe Practices Become trained and read the instructions before working on the machine or welding or cutting. Read and understand the Safety Data Sheets (SDSs) and the manufacturer's instructions for adhesives, coatings, cleaners, consumables, coolants, de- greasers, fluxes, and metals. Wear approved safety glasses with side shields under your welding helmet or face shield and at all times in the work area.
  • Page 9 Protect yourself from electric shock by insulating yourself from work and ground. Use non-flammable, dry insulating material if possible, or use dry rubber mats, dry wood or plywood, or other dry insulating material big enough to cover your full area of contact with the work or ground and watch for fire.
  • Page 10 Welding sparks can cause fires. Have a fire extinguisher nearby and have a trained fire watcher ready to use it. After completion of work, inspect area to ensure it is free of sparks, glowing embers, and flames. Do not weld on containers that have held combustibles, or on closed containers such as tanks, drums, or pipes unless they are properly prepared according to AWS F4.1 and AWS A6.0 (see Safety Standards in Section 9).
  • Page 11 3. Plasma Arc Cutting Hazards Cutting sparks can cause fire or explosion. Do not cut near flammable material or where the atmosphere can contain flammable dust, gas, or liquid vapors (such as gasoline). Move flammables at least 35 feet (11 meters) away or protect them with flame-proof covers (see NFPA 51B listed in Section 9).
  • Page 12 Electric shock from torch or wiring can kill. Wear dry insulating gloves. Do not wear wet or damaged gloves. Do not touch live electrical parts. Do not use worn, damaged, undersized, or repaired cables. Protect yourself from electric shock by insulating yourself from work and ground. Use non-flammable, dry insulating material if possible, or use dry rubber mats, dry wood or plywood, or other dry insulating material big enough to cover your full area of contact with the work or ground.
  • Page 13 Use a ventilating fan to remove fumes from the breathing zone and cutting area. If adequacy of ventilation or exhaust is uncertain, have your exposure measured and compared to the Threshold Limit Values (TLV) in the Safety Data Sheet (SDS). Arc rays can burn eyes and skin.
  • Page 14 4. Special Situations & Equipment Confined spaces can be hazardous. Confined spaces are areas which lack room for full movement and often lack ventilation, such as storage tanks, vats, tunnels, boilers, pipes, hold of a ship, corners of a room, near a ceiling or floor corner, or in a pit. Gases can collect and form dangerous concentrations.
  • Page 15 Electric and magnetic fields (EMF) can affect Implanted Medical Devices. Wearers of Pacemakers and other Implanted Medical Devices should keep away. Implanted Medical Device wearers should consult their doctor and the device manufacturer before going near arc welding, spot welding, gouging, plasma arc cutting, or induction heating operations. Hot parts can burn.
  • Page 16 measures for persons wearing medical implants have to be taken. For example, restrict access for passers−by or conduct individual risk assessment for welders. All welders should use the following procedures in order to minimize exposure to EMF fields from the welding circuit: Keep cables close together by twisting or taping them or using a cable cover.

  • Page 18: Product Description

    The TIGACDC250GD is capable of welding with either AC or DC current. This allows the user to choose DC current welding for carbon steel, stainless steel, copper and many other metals, while also being equipped with the ability to switch over to AC welding used in welding aluminum and aluminum alloys.

  • Page 21: Installation

    INSTALLATION Component setup of this welding machine is a simple, straight forward process. This welder is fitted with a Power Voltage Compensator that takes into consideration a + / - 15% of the rated voltage for this machine. However it is most important to be sure your power supply to this welding is of the proper voltage and is in good condition with clean connections, proper wiring and the correct circuit breakers.

Lets take a moment here to clarify what can be a confusing subject to new users. Generically, when welding, the user has a choice of polarity connections. What is correct for one type of welding may be totally wrong for another type of welding.

  • Page 24 MMA WELDING When using the TIGACDC250GD in the MMA or Stick mode, the connection to the front of the welding machine is usually just the opposite. Stick or MMA welding is done for the most part with Reverse Polarity Electrode Positive That means when you are going to stick weld with the TIGACDC250GD youwould normally connect your electrode holder ( the one that holds your welding rod) to the Positive Dinse Connector and you connect your work clamp (aka ground) to the Negative Dinse Connector.
  • Page 25 The 4T function requires 4 Trigger button movements to start and end a weld. 1 push to start the weld, 2 release to maintain the weld and continue, 3 push the trigger button once again as the first step to ending the weld, and finally 4, release the button to stop the weld.

    OPERATION The ACDCTIG200 welder front panel is designed to be intuitive and easy to use while offering a wide variety of advanced function settings. As a result of the many options the user has at his or her disposal, the Main Control Knob is designed to be a “multi-function”...
  • Page 27 The TIGACDC200GD welder has a very adjustable Pulse feature which can be adjusted multiple ways to offer an almost infinite range of variables. Pulse is just as it implies, a pulsing of amperage power while welding. Pulse Frequency is the number of times per second amperage pulses will occur. The range is 0.5 to 200 HZ, or times per second.

  • Page 34: Maintenance And Check Trouble

    MAINTENANCE AND CHECK TROUBLE 1 Maintenance Dust should be removed with dry and clean compressed air regularly. If the welder is used in a heavily polluted environment with dense smoke and polluted air, dust must be removed from the welder each month. The pressure of compressed air should be reasonable so that damage is not done to small elements in the welder.

  • Page 35: Troubleshooting

    D Unstable current in the operation of the welder： This may be attributed to the following factors： Change in grid voltage； Interference from the power grid or other power equipments. E Severely burn of the tungsten needle The duty cycle is adjusted too large, causing emission from the workpiece to the tungsten electron for too long, resulting in severe heat of the tungsten needles.
