Wire Length For Welding

Keep your stickout length, or the amount of wire exposed between the weld surface and tip, between 3⁄8- to ½-inch. Too high a wire speed or too large a stickout length can result in uneven and ridgy welds, as shown. Starting off, pull the trigger and make a circle for a second or two, then begin your travel making a series of cursive e-shaped movements with the nozzle. Also, check your welds for proper heat range. Too hot and you’ll see some undercutting of the material, as shown. Too low and the weld bead won’t penetrate and will appear to be sitting on top of the material.
