Explain the difference between AC welders and DC welders
What will be an ideal response?
AC welders use alternating current. Transformers in these welders convert high voltage and low
amperage to low voltage and high amperage. Alternating current (AC) is current that reverses its
direction of flow frequently. DC welders use direct current. Direct current flows in one direction only
in accordance with how the welder is set. A generator produces the direct current.
