To produce the best results hold a short arc travel at a uniform speed and feed the electrode downward at a constant rate as it melts. End View Of Work Angle Side View Of Electrode Angle Hold the electrode nearly perpendicular to the work although tilting it ahead in the direction of travel will be helpful.

Limit weave width to a maximum of 2-1 2 times diameter of electrode. 3 S-0054-A Notes Work like a Pro Pros weld and cut safely. Read the safety rules at the beginning of this manual. 155 095 Page 10 Simpo PDFdMerge andSplit Un registeredVersion - http www.simpopdf.com IMPORTANT Weld bead shape is affected by electrode angle arc length travel speed and thickness of base metal. 155 095 Page .
