How To Set Up Arc Welding Machine. Setting the amperage on a welding machine whether Stick SMAW MIG GMAWtypically uses voltage setting or TIG GTAW depends on some key variables such as application and base material welding process and electrode. Not all Scratch TIG torches will fit normal DC inverter MMA machines.
Now supplying the power from the machine to the electrodes by. Make sure the plugs fit. Setting the amperage on a welding machine whether Stick SMAW MIG GMAWtypically uses voltage setting or TIG GTAW depends on some key variables such as application and base material welding process and electrode.
Open the cabinet of the machine Unscrew the cap from the spindle and gently insert the wire spool into it Open the pressure release on the feeder and adjust the tightness by twisting the pressure roll Through the drive roll entry gently insert the MIG wire.
The electric arc is produced when two conductors are touches together and then separated by a small gap of 2 to 4 mm such that the current continues to flow through the air. Because the torch has no control from the machine the arc is started by manually scratching the surface or the metal. Try them at around 70 amps and then go up or down as needed. The power supply for a Stick welder can be AC DC or both it actually depends on the type of machine you are using.
