Benchtop Dual-Gun Automatic Spot Welding Station for Aluminum Alloys — Two Independently Controllable Guns, 100-250KVA, Alternate or Simultaneous Operation

Aluminum sheet metal welding is challenging: high thermal conductivity pulls heat away from the weld zone, while the oxide layer requires higher initial current to break through. Single-gun stations create a bottleneck because each weld cycle must complete before the next begins. This Xinwei benchtop dual-gun welder lets two independently controlled guns operate in alternate or simultaneous mode. While one gun welds, the operator positions the next part on the other gun, effectively doubling throughput without additional floor space. The benchtop form factor fits standard workbench setups, making it accessible for small to medium fabrication shops.
