Equivalence to a High Frequency Start

RE: Equivalence to a High Frequency Start
The equipment I have used for lift start was much more foregiving when crawling through pipe racks and covered with sweat.
In many cases scratch start is used with a regular CC power source.
If your reference to "procedure" is an ASME Sec IX WPS. The arc initiation method is not controlled.
