These machines also lacked a preheating capability, which was found to be necessary in order to reduce the temperature differential at the point of solder melting. This measure prevents wicking and other undesirable characteristics that can develop when one part of a solder...

.... Preheating is generally carried out in the temperature range from 200 to 300 °C (400 to 600 °F). In multipass welds, interpass temperatures must be maintained at the same level, and it is frequently beneficial to hold this temperature for some time after arc extinction to permit further hydrogen diffusion...
