5. Setup

5.1 Welding Machine Setup

  1. Unpack: Carefully remove all components from the packaging.
  2. Connect Ground Clamp: Attach the ground clamp cable to the appropriate terminal on the welding machine. Ensure a secure connection.
  3. Power Connection: Connect the welding machine to a suitable 110V power outlet. Ensure the power source matches the machine's requirements.
  4. Electrode Insertion: Insert the desired welding electrode (e.g., E6013 or E7018) into the electrode holder. Ensure it is firmly seated.

5.2 Welding Helmet Setup

  1. Battery Check: The helmet comes with a pre-installed battery. Check the low battery indicator. If needed, replace the lithium battery (CR2450) as per the helmet's user manual.
  2. Lens Protection Film: Remove any protective films from both sides of the inner and outer lenses.
  3. Fit Adjustment: Adjust the headgear for a comfortable and secure fit. Ensure the helmet sits properly on your head and can be flipped up and down smoothly.
  4. Function Test: Press the "TEST" button on the helmet to verify the auto-darkening function. The lens should momentarily darken and then return to clear. If it does not, check the battery and ensure the sensors are clean.

6. Operating Instructions

6.1 Welding Machine Operation

  1. Power On: Turn on the welding machine using the power switch. The digital display will illuminate.
  2. Current Adjustment: Use the single knob to adjust the welding current (0-90A) according to the electrode type and material thickness. Refer to electrode manufacturer guidelines for recommended current settings.
  3. Grounding: Securely attach the ground clamp to the workpiece or a clean, bare metal surface connected to the workpiece. A good ground connection is crucial for stable arc.
  4. Welding: With the welding helmet on and properly adjusted, strike an arc by touching the electrode to the workpiece and quickly lifting it slightly. Maintain a consistent arc length and travel speed for optimal results.
  5. Cooling: The internal cooling fan will operate during use to prevent overheating. Allow the machine to cool down after extended periods of welding.

6.2 Welding Helmet Operation

  1. Shade Adjustment: Adjust the shade level knob (5-9/9-13) based on the welding process and current. For grinding, select the GRIND(4) mode.
  2. Sensitivity Control: Adjust the sensitivity knob to control how easily the helmet detects the welding arc. Higher sensitivity is suitable for low-amp welding.
  3. Delay Control: Adjust the delay knob to set the time the lens remains dark after the arc stops. A longer delay is useful for tack welding or when the workpiece remains bright.
  4. Wearing the Helmet: Always wear the helmet in the down position when welding. The auto-darkening lens will automatically darken upon arc ignition.
