Yes, the maximum is 4.0mm.

Stainless steel cold welding machines use a wide range of welding materials, including various hardness wires or electrodes with diameters below 4.0mm. The welding strength is high, the welding part has no annealing, no cracks, and no deformation. It can pass various flaw detection inspections after processing. ?

There is no heat input during the instant process of lamination, so there is no deformation, undercut and residual stress. No local annealing will occur, and no re-heat treatment is required after repair. The welding machine overcomes the impact of ordinary argon arc welding on the periphery of the workpiece during the welding repair process, and can safely repair the machined surface of the workpiece without any margin.

Relevant requirements for stainless steel cold welding machines:

1. When using a switching power supply, when the voltage changes within the range of ±20% , the machine can still work normally and maintain stable output power.

2. Round wire repair materials can be used for repair without losing the original datum plane. There is less excess solder and it is easy to reshape later. Using microcomputer chip control, various materials with different diameters can obtain optimal power.

3. The discharge time and current size are controlled by the chip program. The current time can be accurately set according to needs to ensure that the input energy is only enough for the fusion between the welding wire and the workpiece, and there will be no The energy acting on the workpiece is affected by heat to a minimum, thereby achieving ideal repair and welding effects.
