For those applications requiring shorter flashing times, a range of 1 to 3 seconds using a 6" diameter pulley may be specified.

These are standard flash times for Low Carbon and Stainless steels. They may be shortened for non-ferrous alloys. The hydraulic servo control can provide additional welding functions including pre-heat, post heat or chill and temper.
