Power Pilot Lamp: The pilot lamp indicates that the machine is on when lit. 3. Alarm Pilot Lamp: When the machine has less voltage, is over current, or overheating, this pilot lamp will light up to indicate that the thermal overload protection has been activated. 4.
STICKWELD 140STL STICK/ARC Welding (Also known as MMA-Manual Metal Arc or Shielded Metal Arc Welding-SMAW) Connect the Stick torch to the - terminal and Torch Control receptacles. Connect the ground clamp to the + terminal and clamp the metal to be welded. Reverse the torch and ground connections for DCEP (Direct Current Electrode Positive). DC Stick - Select Stick, DC, desired amps using Base cur knob, Pulse Mode off. 1. Insert electrode into electrode holder.
STICKWELD 140STL 4. Use the Current control to change arc qualities. Adjust the amperage according to the recommendations of the electrode (welding rod) manufacturer for the type and size of the electrode used. Experimentation will be required to find the optimal setting desired. It is an excellent tool for out of position welding. 5. Electrode selection.

STICKWELD 140STL Proper weld identification: Overlap and undercutting are two main causes of weld failure. Proper washing of the weld bead into the sides or “toes” of the weld is important. Keep the welding electrode or the TIG tungsten and welding arc within the weld joint to prevent overlap. Pausing on the sides of the welds to wait for the sides to fill reduces the chance of undercutting, even if the current is a little too high.
