2. Safety Information

WARNING: Welding can be dangerous. Always follow safety precautions to prevent injury or death.

• Electric Shock: Can kill. Do not touch live electrical parts. Wear dry welding gloves and protective clothing. Insulate yourself from work and ground.
• Fumes and Gases: Can be hazardous to your health. Keep your head out of the fumes. Use enough ventilation or exhaust at the arc to keep fumes and gases away from the breathing zone.
• Arc Rays: Can injure eyes and burn skin. Wear a welding helmet with a proper shade of filter to protect your face and eyes when welding or watching. Wear appropriate safety glasses with side shields. Wear protective clothing made from durable, flame-resistant material.
• Fire and Explosion: Welding sparks can cause fire or explosion. Keep flammable materials away from the welding area. Have a fire extinguisher nearby.
• Burns: Hot metal can cause severe burns. Do not touch hot parts with bare hands.
• Overheating: The machine has built-in over-current, over-voltage, and over-temperature protection. If the protective light illuminates, the machine needs to stop working and cool down.

5. Setup

5.1 Power Connection

Ensure the welding machine is connected to a suitable power supply (110V or 220V, depending on the model and region). The machine is designed for dual voltage operation. Always use a grounded outlet.

5.2 Wire Reel Installation (MIG/MAG Mode)

The HBM200 supports 1KG flux cored wire reels (0.8mm and 1.0mm).

1. Open the side panel of the welder.
2. Place the wire spool onto the spool holder. Ensure the wire unwinds from the bottom of the spool.
3. Secure the spool with the spool lock, spring, and spool spacer as shown in the diagram.
4. Feed the wire through the wire guide and into the wire feeder mechanism.
5. Ensure the correct wire feed roller (0.8mm or 1.0mm) is installed, matching your wire diameter.
6. Close the side panel.

5.3 Connecting Welding Accessories

• Ground Clamp: Connect the ground clamp cable to the negative (-) terminal on the front panel. Attach the clamp securely to the workpiece.
• MIG Torch: Connect the MIG torch cable to the positive (+) terminal on the front panel.
• Electrode Holder (for MMA/ARC): Connect the electrode holder cable to the positive (+) terminal on the front panel.
• TIG Torch (for TIG-lift): Connect the TIG torch cable to the negative (-) terminal on the front panel. Ensure the TIG torch has a gas connection if using shielded TIG.

6. Operating Instructions

6.1 Powering On

After connecting all cables and ensuring proper setup, turn on the main power switch located on the rear of the machine.

6.2 Selecting Welding Mode

Use the Function Mode Button (integrated into the wire speed knob) to cycle through the available welding modes: MIG/MAG, MMA/ARC, and TIG-lift. The selected mode will be indicated on the digital display.

6.3 Adjusting Welding Parameters

• Current Adjustment: Use the Current Adjust Knob to set the desired welding amperage.
• Wire Speed Adjustment (MIG/MAG): Use the Wire Speed Adjust Knob to control the wire feed speed. Match the wire feed speed to the thickness of the workpiece for optimal results.
• Flux Wire Diameter (MIG/MAG): In MIG mode, press the wire speed knob once to toggle between 0.8mm and 1.0mm flux wire settings.

6.4 Welding Process

Always wear appropriate personal protective equipment (PPE) including a welding helmet, gloves, and protective clothing before starting any welding operation.

• MIG/MAG (Gasless): Position the MIG torch close to the workpiece. Press the trigger to start the arc and wire feed. Maintain a consistent travel speed and arc length.
• MMA/ARC: Strike the electrode against the workpiece to initiate the arc. Maintain a steady hand and appropriate arc length.
• TIG-lift: Touch the tungsten electrode to the workpiece, then lift slightly to initiate the arc. Maintain a small gap and feed filler rod manually if required.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your welding machine.

• Cleaning: Regularly clean the machine's exterior with a dry cloth. Use compressed air to blow out dust from the ventilation openings. Ensure the machine is unplugged before cleaning.
• Check Connections: Periodically inspect all electrical connections, cables, and torch components for wear, damage, or loose connections. Replace any damaged parts immediately.
• Wire Feeder: Keep the wire feeder mechanism clean and free of debris. Ensure the wire feed roller is not worn and matches the wire diameter.
• Nozzles and Tips: Replace MIG nozzles and contact tips as they wear out to maintain good arc performance.
• Storage: Store the welding machine in a dry, clean environment, away from excessive dust, moisture, and corrosive materials.

8. Troubleshooting

The HBM200 is equipped with several protective features to ensure safe operation. If you encounter issues, refer to the following common troubleshooting steps:

• Machine Shuts Down / Protective Light On: This indicates over-current, over-voltage, over-temperature, or overload. Turn off the machine, unplug it, and allow it to cool down for at least 15-20 minutes. Check for proper ventilation and ensure the input voltage is stable.
• No Arc / Weak Arc: Check all cable connections (power, ground, torch). Ensure the ground clamp has good contact with the workpiece. Verify the correct welding mode is selected and parameters (current, wire speed) are set appropriately for the material and thickness.
• Poor Weld Quality: Adjust welding parameters (current, wire speed). Ensure the workpiece is clean and free of rust or paint. Check for proper wire feed and contact tip condition.
• Wire Feeding Issues (MIG/MAG): Check if the wire spool is installed correctly and unwinding smoothly. Ensure the wire feed roller matches the wire diameter and is clean. Inspect the MIG torch liner for blockages or kinks.
