2. Safety Information

Always prioritize safety when operating welding equipment. Failure to follow safety guidelines can result in serious injury or damage to the equipment. Read and understand all instructions before use.

• Electric Shock: Welding current can cause fatal electric shock. Ensure proper grounding and insulation. Never touch live electrical parts.
• Fumes and Gases: Welding produces fumes and gases that can be hazardous to health. Work in a well-ventilated area or use local exhaust ventilation.
• Arc Rays: Arc rays can burn eyes and skin. Wear appropriate welding helmet with proper shade filter, protective clothing, and gloves.
• Fire and Explosion: Welding sparks and hot metal can cause fire or explosion. Keep flammable materials away from the welding area. Have a fire extinguisher readily available.
• Burns: Hot metal and equipment can cause severe burns. Use heat-resistant gloves and protective clothing.
• Electromagnetic Fields (EMF): Welding current creates EMF. Consult a physician if you have a pacemaker or other medical device.
• Maintenance: Disconnect power before performing any maintenance or service.

4. Setup

4.1 Power Connection

Connect the welding machine to a stable 230V - 16A power supply. Ensure the power outlet is properly grounded and capable of handling the required current. The machine is designed to operate efficiently even with domestic 3kW meters.

4.2 Wire Spool Installation (MIG/FLUX)

The Telwin Maxima 200 is prepared for use with wire spools of 100mm and 200mm diameter. Follow the instructions in the machine's internal compartment for correct wire feeding and tension adjustment. Ensure the wire type matches your welding process and material.

4.3 Torch and Ground Clamp Connection

1. Connect the MIG torch (MT15) to the centralized torch attachment point on the front panel of the welder.
2. Attach the ground clamp (Toledo) to the appropriate terminal on the welder. Ensure a clean, secure connection to the workpiece to be welded.
3. For MMA welding, connect the electrode holder clamp (Dallas 300) to the positive terminal and the ground clamp to the negative terminal (or vice-versa depending on electrode polarity).

4.4 Gas Connection (for MIG-MAG/Brazing)

If performing MIG-MAG or Brazing welding, connect the gas cylinder using the provided connection kit. Ensure all connections are tight and leak-free. Use the correct shielding gas for your specific welding application (e.g., Argon for aluminum, CO2 or Argon/CO2 mix for steel).

5. Operating Instructions

5.1 Selecting Welding Process

Turn on the welder. Use the intuitive control panel to select your desired welding process: Flux, MIG-MAG, Brazing, MMA, or TIG DC-LIFT. The machine's polarity can be changed for MIG-MAG/Brazing welding without gas.

5.2 Synergic Parameter Adjustment

The Maxima 200 features synergistic parameter adjustment, simplifying the setup process. The intuitive panel offers three main adjustments to begin welding:

• Process: Select the welding process (e.g., MIG, MMA).
• Bead Shape: Adjust for desired weld bead characteristics.
• Thickness: Set the material thickness you are welding.

The electronic control (inverter) ensures arc stability, providing excellent results even for less experienced operators.

5.3 MMA Welding (Electrode)

For MMA welding, the machine offers advanced features:

• Arc-Force: Automatically adjusts the welding current to prevent the electrode from sticking.
• Hot-Start: Provides an initial boost of current to ensure easy arc ignition.
• Anti-Stick: Reduces the current if the electrode sticks, allowing for easy removal without damaging the electrode or workpiece.

The Maxima 200 can weld both rutile and basic electrodes up to 3.2mm in diameter.
