2. Important Safety Information

Always prioritize safety when operating welding equipment. Failure to follow safety guidelines can result in serious injury or death.

General Safety Precautions:

• Electric Shock: Welding current can cause fatal electric shock. Ensure proper grounding. Do not touch live electrical parts. Wear dry welding gloves and protective clothing.
• Fumes and Gases: Welding fumes and gases can be hazardous to your health. Work in a well-ventilated area. Use a fume extractor if necessary.
• Arc Rays: Arc rays can burn eyes and skin. Wear a welding helmet with appropriate shade filter, safety glasses, and protective clothing.
• Fire and Explosion: Welding sparks and hot metal can cause fires or explosions. Keep flammable materials away from the welding area. Have a fire extinguisher readily available.
• Hot Parts: Welded materials and equipment can remain hot for a long time. Allow them to cool before handling.
• Pacemakers: Magnetic fields from high currents can affect pacemakers. Consult your doctor before welding.

4. Setup Instructions

4.1 Power Connection

• The HBM145 supports both 110V and 220V power inputs. Use the provided adapter plug for the appropriate voltage.
• Ensure the power source is stable and capable of supplying the required current (up to 145A).
• Connect the power cable securely to the welder and a grounded electrical outlet.

4.2 Wire Feeding System (MIG/Flux Core)

The welder features a reliable wire feed system for consistent performance.

1. Open the wire feed compartment.
2. Place the wire spool onto the spindle, ensuring it rotates freely. The HBM145 is suitable for 2 LBS .030'' & .039'' flux core wire.
3. Thread the wire through the guide tube and feed roller.
4. Close the pressure arm on the feed roller to apply appropriate tension.
5. Feed the wire through the MIG gun liner until it emerges from the nozzle.

4.3 Connecting Welding Cables

• Earth Clamp: Connect the earth clamp cable to the positive (+) terminal for flux core welding or negative (-) terminal for solid wire MIG (if using gas). Attach the clamp securely to the workpiece, ensuring good electrical contact.
• MIG Torch: Connect the MIG torch cable to the appropriate terminal (usually negative (-) for flux core, positive (+) for solid wire MIG).
• Electrode Holder (MMA): For MMA welding, connect the electrode holder to the positive (+) terminal and the earth clamp to the negative (-) terminal.
• Lift TIG Torch (Optional): If using a Lift TIG torch (purchased separately), connect it to the negative (-) terminal and the earth clamp to the positive (+) terminal.

Important Polarity Note: For flux core welding, set the wire to negative polarity and the return clip (earth clamp) to positive polarity. This is the opposite of gas-shielded welding and helps minimize splatter.

5. Operating the Welder

The HBM145 offers multiple welding processes. Familiarize yourself with the control panel and settings for each mode.

5.1 Control Panel Overview

The large LED digital display provides clear feedback on welding parameters. Use the control knob and mode button to navigate and adjust settings.

• Mode Button: Cycles through welding processes (MIG, TIG, MMA).
• Control Knob: Adjusts amperage, wire feed speed, and other parameters depending on the selected mode.
• Synergic Control: In MIG mode, adjusting the wire feeding speed automatically matches the voltage for optimal welding.

5.2 Welding Modes

5.2.1 Gasless MIG Welding

• Select MIG mode on the control panel.
• Ensure correct polarity for flux core wire (negative wire, positive earth clamp).
• Select the appropriate wire size (e.g., 0.030" or 0.039").
• Adjust wire feed speed using the synergic control. The voltage will automatically adjust.
• Begin welding, maintaining a consistent travel speed and arc length.

5.2.2 MMA (Stick) Welding

• Select MMA mode.
• Connect the electrode holder to the positive (+) terminal and the earth clamp to the negative (-) terminal.
• Insert the welding electrode into the holder.
• Adjust the amperage according to the electrode type and material thickness.
• The machine features Hot Start for easier arc ignition and Anti-sticking to prevent electrodes from sticking.

5.2.3 Lift TIG Welding (Optional)

• Requires a separate Lift TIG torch (e.g., WP17V).
• Select TIG mode.
• Connect the TIG torch to the negative (-) terminal and the earth clamp to the positive (+) terminal.
• Adjust amperage.
• Initiate the arc by gently touching the tungsten electrode to the workpiece and lifting slightly.

5.2.4 Spool Gun Welding (Optional)

• Requires a separate spool gun.
• Connect the spool gun to the designated port on the welder.
• This mode is primarily for gasless welding and offers rapid wire feeding capabilities and improved arc stability.

6. Maintenance

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

General Maintenance:

• Cleaning: Periodically clean the welder's exterior with a dry cloth. Use compressed air to blow out dust from inside the machine, especially the cooling fan and vents. Ensure the power is disconnected before cleaning.
• Cable Inspection: Regularly inspect all welding cables, torch, and earth clamp for damage, cuts, or loose connections. Replace damaged components immediately.
• Wire Feed System: Clean the wire feed rollers and guide tubes to prevent wire jamming or inconsistent feeding. Check for wear on the feed rollers.
• MIG Torch Nozzle/Tips: Clean or replace MIG nozzles and contact tips as they wear out or become clogged with spatter.
• Storage: Store the welder in a dry, clean environment away from excessive dust and moisture.
