4.04 Power Source Compatibility
If the Thermal Arc power source only offers a 14 pin amphenol connector, a 870093B-001 adapter cable will be
required to connect between the 19 pin control cable of the VA 4000 S contoller and the 14 pin amphenol connector
of the power source.
The Ultrafeed VA 4000 S will also work with most competitive power sources that provide 115 VAC and require a relay
closure to become energized.
