          Tighten the ground clamp on your Miller Thunderbolt 160, loose grounds cause arc wandering, use 130 amps.

            Store e6013 electrodes dry, old ones cause arc wander, set Miller Thunderbolt to 120 amps.

              Use DCEP polarity on your Miller Thunderbolt 160, improves arc stability, set to 120 amps.
