The approximate temperature of a SMAW arc is _____ degrees F.

• A. 6500-7000
• B. 10000-10500
• C. 5600-6300
• D. 7600-8500

Answer: (A)

The heat produced by a SMAW arc is extremely high, and the most commonly cited range for this process is about 6500 to 7000 °F. That level of temperature is hot enough to melt the base metal and the filler electrode, which is essential for the welding process to form a bead. While the exact temperature can vary with current, electrode size and type, and the material being welded, 6500–7000 °F is the standard figure used in practice and exams. The other ranges listed are not typical for a SMAW arc under normal welding conditions; they either overestimate or underestimate the energy of the arc compared to the standard SMAW value.
