not exceed 1/4 inch or the arc may begin sputtering, signaling a loss in welding
performance.
d. TUNING IN THE WIRE SPEED - This is one of the most important parts of wire welder
operation and must be done before starting each welding job or whenever the voltage
setting, or wire diameter is changed.
⚠WARNING
EXPOSURE TO A WELDING ARC IS EXTREMELY HARMFUL TO THE EYES AND SKIN!
• Prolonged exposure to the welding arc can cause blindness and burns. Never strike an arc or begin
welding until you are adequately protected. Wear flame-proof welding gloves, a heavy long-sleeved
shirt, trousers without cuffs, high topped shoes, and an ANSI approved welding helmet.
e. Connect the Ground Clamp to a scrap piece of the same type of material which you will
be welding. It should be equal to or greater than the thickness of the actual work piece,
and free of oil, paint, rust, etc.
f. Select a heat setting.
g. Hold the torch in one hand. Hold the wire just off the work piece. (See step 2 above:
HOLDING THE TORCH, if you are uncertain of the angle at which you will be welding.)
h. Set the wire feed speed based on the thickness of material and the set-up chart on the
back side of the wire feeder door.
i. Lower your welding helmet and pull the trigger on the torch and let the wire feed into
the work piece to start an arc, and then begin to drag the torch toward you.
j. LISTEN! If the arc is sputtering, increase the wire speed slightly and try again. Continue
increasing the wire speed adjustment until you achieve a smooth buzzing sound. If the
wire seems to "pound" into the work piece, decrease wire speed slightly and try again.
Use the wire speed control to slightly increase or decrease the heat and penetration
for a given voltage setting by increasing or decreasing the wire speed slightly. Repeat
this tune-in procedure if you select a new voltage setting, a different wire diameter, or
a different roll of wire.

⚠WARNING
ELECTRIC SHOCK CAN KILL!
• To prevent ELECTRIC SHOCK, do not perform any welding while standing, kneeling, or lying directly
on the grounded workpiece.
