SAFETY CONTROLS Stick Weld Diagnosis - Workpiece Heat Control / Weld Penetration INADEQUATE PENETRATION PROPER PENETRATION EXCESS PENETRATION OR BURN-THROUGH Not hot enough Ideal heat Too hot How to increase workpiece heat and increase penetration: (to weld THICKER workpieces properly) a.Increase current. b.Weld more slowly. How to reduce workpiece heat and limit penetration: (to weld THINNER workpieces properly) c. Decrease current. d.Weld more quickly. Example Stick Weld Diagrams CLEAN WELDS FIRST! Stick welds will have a coat of slag over them until cleaned. Good Weld Current Too Low TO CORRECT: Increase the current Current Too High TO CORRECT: Decrease the current Weld Speed Too Fast TO CORRECT: Weld slower Weld Speed Too Slow TO CORRECT: Weld faster Arc Length Too Short TO CORRECT: Increase distance Arc Length Too Long TO CORRECT: Decrease distance BASIC WELDING WELDING TIPS MAINTENANCE Page 16 For technical questions, please call 1-888-866-5797.
