Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a double-wire double-drive self-adjusting straight wire feeding assembly. Background Art

[0002] The wire feeder is an important equipment in the laser welding process. Its function is to pull and transport the welding wire and provide solder for the welding gun. The welding wire is mostly packaged in a coiled form. During transportation, there will be natural bends on the welding wire due to long-term coiling.
