When you squeeze the trigger on the torch, a small electric motor in the machine rotates a drive roller. This roller pulls the solid or flux-cored wire from the spool, pushes it through a plastic liner inside the torch cable, and out through the contact tip. Simultaneously, an electrical current is sent to the wire, creating an arc with the base metal that melts the wire and forms the weld bead.
Mastering the two controls on your Solar 2150—Voltage (Power) and Wire Feed Speed—is the key to a strong, clean weld.
