FAQ:
Q: Can DC TIG weld aluminum?
A: DC TIG with helium can weld aluminum, but its hot arc and deep penetration may be best for thicker welds. DC TIG with argon and flux can weld aluminum, but visibility, preparation, and cleanup are not great.
Q: What is AC welding machine?
A: Derisively referred to as “buzz boxes,” AC welding machines are considered entry-level technology. AC welding might also be used to fix arc blow problems. This phenomenon is marked by an arc that wanders or blows out the joint being welded.
Q: What is an inverter arc welder?
A: An inverter welder is a type of welding power supply capable of providing a high current for welding. The welder uses a series of rectifiers and solid-state switches to convert 60 Hz alternating current (AC) input power into direct current (DC) output power.
