How to adjust the wire extension of the welding robot

The specific value of the wire extension length for welding robots depends on the welding process and workpiece specifications. Generally speaking, the extension length of the welding wire is more suitable between 10-15mm; However, in practical operation, there may be interference issues between the nozzle outer diameter and the workpiece or positioning, resulting in wire elongation exceeding 15mm. In addition, as the extension length of the welding wire increases, the resistance heat will also increase, which will accelerate the melting speed of the welding wire and improve production efficiency; However, when the extension length is too large, it can easily cause the welding wire to overheat, cause segment melting, and exacerbate splashing, thereby affecting the stability of the welding process.

For short-circuit transition welding, the appropriate extension length range is 6-13mm; Other forms of droplet transfer welding require a suitable extension length range of 13-25mm. In addition, when selecting the appropriate extension length, it should also be considered to set it to 10-12 times the diameter of the welding wire. To adjust the wire extension on the robot equipment, please follow the steps below:

① Open the controller and find the wire extension amount in the parameter settings;

② Adjust this option to within the required numerical range (generally between 15-25mm is more appropriate);

③ Check and adjust the corresponding arc length settings. The extended length of the welding wire may not match the arc length of the welding wire, and it is necessary to ensure that the two are coordinated and adjusted as necessary;

④ Find the arc length of the welding wire in the parameter settings in the controller and set it to an appropriate value; Normally, the arc length of the welding wire is directly proportional to the amount of wire extension, so it needs to be adjusted accordingly;

⑤ Repeat the experimental test under the same conditions and observe the results to determine if the ideal state has been achieved, until it is adjusted appropriately.
