- Short Circuit Transfer - feed wire touches molten metal pool, which kills the plasma arc. The surface tension of the molten pool pulls away from the feed wire, which restates the plasma arc. The cycle then repeats.
- Globular
- feed wire never touches the motion metal pool. The feed wire melts in the plasma above the molten poll. A single, large droplet of metal collects at the tip which eventually drops into the molten pool. This requires less power than Spray Transfer, but the quality and penetration is not as good. The droplet size is irregular and the position it falls into the molten pool will vary from the center.
- Spray Transfer
- feed wire never touches the molten metal pool. The feed wire melts in the plasma above the molten pool. The magnetic field pulls the droplets off the feed wire as a fine spray. Requires higher power giving more heat and a larger pool.
