This image shows the Power Cable input, Power Switch, and Input Gas connection on the rear panel.

5.1 Power Connection

1. Ensure the power switch on the rear panel is in the 'OFF' position.
2. Connect the power cable to the machine. The HBT2000 supports both 110V and 220V input. Use the provided 110V to 220V adapter cable if necessary.
3. Plug the power cable into a suitable power outlet.

5.2 Welding Cable Connections

The HBT2000 features quick connectors for easy and secure attachment of welding cables, minimizing gas leaks.

This diagram illustrates the simple three-step process for connecting the quick connectors, ensuring a tight fit.

5.2.1 MMA/ARC Mode Connections

1. Connect the Ground Clamp cable to the '-' (negative) pole on the front panel.
2. Connect the Electrode Holder cable to the '+' (positive) pole on the front panel.

5.2.2 TIG Mode Connections

1. Connect the TIG Torch cable to the '-' (negative) pole on the front panel.
2. Connect the Ground Clamp cable to the '+' (positive) pole on the front panel.
3. Connect the gas tube from your shielding gas cylinder to the 'Input Gas' connector on the rear panel. Secure with tube locks.
4. Connect the TIG torch gas line to the 'Gas Output' connector on the front panel.

5.3 Visual Setup Guide

6. Operating Instructions

The HBT2000 offers both TIG and MMA (ARC) welding functions. Select the appropriate mode and adjust settings according to your welding requirements.

This image provides an overview of the TIG function (10-200A, Tungsten diameter 1.0-3.2mm, welding thickness 0.5-6.0mm) and MMA function (10-170A, Electrode diameter 2.5-4.0mm, welding thickness 1.5-12mm).

6.1 Mode Selection

Use the buttons on the front panel to select between MMA and TIG welding modes. The digital LCD screen will display the current settings.

6.2 Current Adjustment

Use the rotary knob on the front panel to adjust the welding current (A) according to the material thickness and type. The digital display shows the current value.

6.3 TIG Specific Functions

This image illustrates the 2T (Manual) and 4T (Semi-automatic) operative modes, explaining how 4T reduces finger fatigue for medium thickness plates.

• 2T (Manual) Mode: Press and hold the torch trigger to weld. Release to stop. Ideal for short welds or tack welding.
• 4T (Semi-automatic) Mode: Press and release the torch trigger to start welding. Press and release again to stop. This mode reduces finger fatigue during longer welding operations.
• Downslop Function: This feature helps decrease the current linearly at the end of a weld, protecting the weld surface and creating a cleaner finish.

6.4 Material Compatibility

The HBT2000 is suitable for welding a wide range of metals:

This image visually lists the types of metals compatible with the HBT2000, including Cast Iron, Mild Steel, Sheet Metal, Stainless Steel, Square Pipe, and Metal Cage.

• Cast Iron
• Mild Steel
• Sheet Metal
• Stainless Steel
• Square Pipe
• Metal Cage

7. Maintenance

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

• Cleaning: Periodically clean the machine's exterior and ventilation openings to prevent dust and debris buildup. Use compressed air to clear internal components if necessary, ensuring the machine is unplugged.
• Cable Inspection: Regularly inspect all welding cables, ground clamps, and electrode holders for damage, fraying, or loose connections. Replace any damaged components immediately.
• Gas System (TIG): For TIG welding, check gas hoses and connections for leaks. Ensure the gas cylinder is securely stored and regulated.
• Consumables: Replace worn-out TIG torch consumables (collets, collet bodies, ceramic nozzles, tungsten electrodes) and MMA electrodes as needed.
• Storage: Store the welding machine in a dry, clean environment, away from excessive dust, moisture, and corrosive materials.

8. Troubleshooting

This section provides basic troubleshooting steps for common issues. For more complex problems, contact customer support.

• No Power: Check the power cable connection, ensure the power switch is ON, and verify the power outlet is functional. Check for tripped circuit breakers.
• No Arc: Ensure welding cables are correctly connected and secure. Check the ground clamp connection to the workpiece. Verify the correct welding mode is selected and current settings are appropriate.
• Poor Weld Quality: Adjust welding current, travel speed, and arc length. Ensure the workpiece is clean and free of contaminants. For TIG, check gas flow and tungsten electrode condition.
• Overheat Protection Activated: If the machine stops and an overheat indicator lights up, allow the machine to cool down. Ensure ventilation is not obstructed and the duty cycle is not exceeded.
• Gas Leak (TIG): Check all gas hose connections, including those to the cylinder, machine, and torch. Tighten any loose fittings.

9. User Tips

Enhance your welding experience with these practical tips:

• Practice Makes Perfect: Start with scrap pieces of metal to get a feel for the machine and different settings before working on your main project.
• Cleanliness is Key: Always ensure your workpiece is clean and free of rust, paint, oil, or other contaminants for the best weld quality.
• Tungsten Preparation (TIG): Properly grind your tungsten electrode to a sharp point for precise arc control. Refer to the tungsten electrode guide in the specifications section.
• Gas Flow (TIG): Maintain a consistent and appropriate shielding gas flow rate to prevent atmospheric contamination of the weld puddle.
• Electrode Selection (MMA): Choose the correct electrode type and diameter for the material and thickness you are welding.
