- Can be used to join almost all metals, with superior weld quality, generally free of defects
- Free from spatter that occurs with other arc welding processes
- Can be used with or without filler metal as required for the specific application
- Provides excellent control of root pass weld penetration
- Can be used to produce inexpensive autogenous (fusion) welds with good penetration
