Safety Tips

Before laser welding, please be sure to watch the safety training video and wear personal protective equipment (laser safety goggles/helmet, mask/face shield, heat-resistant gloves).

Welding Wire Options

Welding wire or not?

Not all welding processes require welding wires.

• For thin plates less than 1mm, the base material can be melted directly to form the weld seam without the need for additional welding wires.
• If the weld seam is relatively small, it can also be welded using autogenous welding, which does not require additional welding wires.

Welding wire material

The basic principle is that the base sheet and the welding wire should be of the same material.

Welding wire diameter

Please choose welding wire of proper diameters for metals of different thickness

• The diameter of the welding wire should not be smaller than the gap of the weld, and the thickness of the workpiece is not recommended to be less than the diameter of the wire.
• xTool MetalFab laser welder now supports wires of 0.8mm, 1.0mm, 1.2mm, 1.6mm.
• For metals≥4mm, it's recommended to use 1.2mm wire. For metals of 2-3mm, it's recommended to use 1.2mm wire. For metals ≤1mm. it's recommended to use 0.8mm wire. This is only for recommendation, the final choice should be based on the welding results and demands.

Check Before Welding

Welding Focus Position

Confirm the welding nozzle scale is the same as the suggested value of system settings.

Welding wire position

When installing the wire feeding tube, ensure that the welding wire fits snugly into the groove of the wire feeding nozzle to prevent the wire from being offset.

Red light position

Before welding, check that the welding wire is aligned with the center of the red light.

Protective lens

Check if the lens is dirty or damaged.

Welding Tips

• Choose the proper welding parameters according to your demands. (How to Choose Welding Parameters?) 
• The welding nozzle of the welding gun should be inclined at a 45° angle to the weld seam.

Correct angle:

Incorrect angle:

• The welding wire must not deviate from the weld seam.
• During wire feeding, do not pull the wire with your hand; the wire feeder will drive the welding gun automatically.

• After welding, manually lift the gun to avoid wire sticking.

• It is recommended to perform tack welding first, followed by continuous welding.

• When welding, leave space for deformation.
