Stick Welding; Additionally the SD 4050 Mini is equipped for stick welding or Shielded Metal Arc Welding (SMAW). This method is known for its execution and rapid burning capabilities. The SD 4050 Mini is more, than capable of handling this task allowing you to perform welding with 7018, 6013 and 6011 electrodes. Whether you're working on construction sites or doing repairs the stick welding feature ensures a strong bond between metals.

Lift TIG Welding; Tungsten Inert Gas (TIG) welding is a versatile process known for its smooth welds. While the SD 4050 Mini can perform Lift TIG welding please note that accessories like the TIG torch and tungsten are not included with the machine. If you want to use the TIG welding feature consider using a TIG torch such as the SSimder WP 17V 10-25 Plug TIG torch. Lift TIG welding is ideal when precision and aesthetic quality are required.
