Inverter
Why is AC sometimes preferred in welding?
It prevents arc blow
It creates smoother beads
It gives deeper penetration
It reduces spatter
A motor generator produces welding current by:
Rectifiers
Inverters
Mechanical rotation
Transformers
If a welder wants to minimize spatter, which current type should they use?
AC
DC
Both AC and DC
Neither AC nor DC
Why might a welder choose a transformer-rectifier over a transformer?
To use only AC output
