5. Setup

5.1 Connecting the Power

1. Ensure the welder's power switch is in the OFF position.
2. Connect the power cord to the welder's power input port.
3. Plug the power cord into a suitable 110V power outlet.

5.2 Attaching the Welding Gun

1. Connect the welding gun cable to the designated output terminal on the welder. Ensure a secure connection.
2. Attach the ground clamp to the workpiece or a sturdy metal surface connected to the workpiece.

5.3 Preparing the Workpiece

1. Clean the welding area on the workpiece to remove any rust, paint, oil, or other contaminants.
2. Ensure the workpiece is stable and properly grounded.
3. Select the appropriate stud and collet for your application. Remember, the material of the plate and stud must match.

6. Operating Instructions

6.1 Power On/Off

• To power on, flip the main power switch to the ON position. The digital display will illuminate.
• To power off, flip the main power switch to the OFF position.

6.2 Adjusting Voltage

The welder features an intuitive control panel with a clear digital display and indicator lights to show the voltage range in real-time. Voltage can be easily set based on the stud size.

1. Refer to the recommended voltage settings for your specific stud diameter and material.
2. Use the control knobs or buttons on the panel to adjust the voltage. The digital display will show the current setting.

Figure 6.1: Flexibly Adjustable Voltage. The control panel allows for easy voltage adjustment based on the stud size (M3-M10). The clear digital display and indicator lights provide real-time feedback on the voltage range, ensuring precise control over the welding process.

6.3 Selecting Studs and Collets

Choose the correct stud diameter (M3-M10) and corresponding collet for your application. Ensure the stud material matches the workpiece material for optimal results.

6.4 Welding Process

1. Insert the selected stud into the collet on the welding gun.
2. Position the stud firmly against the workpiece at the desired welding location.
3. Press the trigger on the welding gun. The welder will discharge the capacitor, creating a weld.
4. Hold the stud in place for a moment after the weld to allow it to cool and solidify.
5. Release the trigger and carefully remove the welding gun.
