• A. False
• B. True
• C. Not sure
• D. Depends

Answer: (B)

Short-circuiting transfer is a low-current, low-arc-voltage mode in GMAW where the wire tip actually touches the work and then the arc re-ignites as the molten metal transfers in short bursts. This mode is favored at lower currents because the energy per transfer is small, which keeps heat input low and gives you greater control, especially on thin or dirty surfaces and in all positions. Because it operates with these lower currents, it’s most commonly used when you’re welding at currents under about 200 A. As currents rise toward and above that level, spray transfer becomes more feasible, delivering higher deposition rates but requiring thicker material and cleaner surfaces. So the statement that short-circuiting transfer is used most frequently at current levels less than 200 A is true.
