4. Setup
4.1 Power Connection
The HBM145 welder supports both 110V and 220V input voltages. Ensure the power source matches the welder's requirements and that the circuit breaker can handle the welding current. Use a dedicated circuit if possible.
- Connect the power cord to a suitable electrical outlet.
- Turn on the main power switch located on the rear of the machine.
4.2 Ground Clamp Connection
Always connect the ground clamp securely to the workpiece or welding table. A good ground connection is essential for stable arc and safe operation.
- Insert the ground clamp cable connector into the appropriate terminal on the welder (usually marked with a ground symbol or "-").
- Attach the clamp firmly to a clean, bare metal section of the workpiece, ensuring good electrical contact.
4.3 Wire Installation (MIG/Flux Core)
The HBM145 supports 2 lbs spools of .030" and .039" welding wire.

- Open the side panel of the welder to access the wire spool compartment.
- Place the wire spool onto the spindle, ensuring it rotates freely.
- Feed the wire through the guide tube and into the drive roller mechanism.
- Close the drive roller tension arm and adjust the tension according to the wire diameter.
- With the MIG gun pointed away from yourself and others, press the trigger to feed the wire through the gun liner until it exits the contact tip.
- Trim the wire to approximately 1/2 inch (12-15mm) stick-out.
4.4 MMA (Stick) Welding Setup
- Connect the electrode holder cable to the positive (+) terminal and the ground clamp cable to the negative (-) terminal for DCEN (Direct Current Electrode Negative) or vice-versa for DCEP (Direct Current Electrode Positive), depending on the electrode type.
- Insert the desired welding electrode into the electrode holder.
4.5 Lift TIG Welding Setup (TIG torch sold separately)
- Connect the TIG torch cable to the negative (-) terminal and the ground clamp cable to the positive (+) terminal.
- Ensure a suitable tungsten electrode is installed in the TIG torch.
- Connect the gas hose from the TIG torch to a suitable shielding gas cylinder (e.g., Argon) with a regulator.
4.6 Spool Gun Welding Setup (Spool gun sold separately)
The HBM145 supports spool gun welding for gasless applications. Aluminum welding is not supported with the spool gun.

- Connect the spool gun cable to the designated port on the front panel of the welder.
- Ensure the wire spool inside the spool gun is correctly loaded and threaded.
5. Operating Instructions
5.1 Control Panel Overview
The HBM145 features a large LED display and intuitive controls for easy operation.

- LED Display: Shows current welding mode, wire diameter, current/voltage, and other settings.
- MODE Button: Press to cycle through welding modes (MIG, MMA, Lift TIG).
- SET Button: Used to select parameters for adjustment within a mode.
- Control Knob: Rotate to adjust current, voltage, or wire feed speed depending on the selected parameter.
5.2 MIG Welding (Flux Core / Gasless)
- Select MIG Mode: Press the MODE button until MIG is selected on the display.
- Select Wire Size: Use the SET button to highlight the wire diameter setting, then use the control knob to select the correct wire size (e.g., Flux Φ0.8 or Flux Φ1.0).
- Adjust Current: The synergic control will suggest a current. You can fine-tune the current using the control knob.
