Welcome to our guide on using a handheld welding machine. Proper parameter adjustments are crucial for achieving high-quality welds. This article will provide essential welding principles, a detailed process example, and tips for fine-tuning your machine.
1. Plate Thickness and Wire Thickness:
●Thicker plates require thicker wires.
●Thicker plates and wires need higher power settings.
●Wire feeding should be slower for thicker materials.
●Lower power settings result in a whiter weld surface.
●Higher power settings can change the weld color from color to black, indicating one-sided forming.
3. Wire Thickness:
●The wire thickness should not exceed the plate thickness.
●Thicker wires can affect the fullness of the weld seam.
●Thinner wires result in a lower scanning width.
●Different brands of lasers may require fine-tuning.
●Aluminum processes need higher power settings (20%-30% more) compared to stainless steel.
●Focus adjustments might be necessary depending on the machine.

NOTE: This data is a reference value and is subject to actual welding.
Initial Settings:
●Welding Wire: 0.8mm Stainless Steel
●Scanning Speed: 350
●Scanning Width: 2
●Peak Power: 350
●Duty Cycle: 100
●Frequency: 2000
●Result: The outgoing light penetrated the plate and caused significant distortion.
●Peak Power: Reduced to 260
●Result: Reduced distortion, but it was still easy to burn through at the beginning of the light out.
Second Adjustment:
●Peak Power: Reduced to 200
●Result: Reduced distortion significantly. Increasing the width to 3 improved the welding effect further.

Fine-tuning your welding parameters is key to achieving optimal results. Use these guidelines as a reference and adjust as needed based on your specific welding tasks. Happy welding!
