Power settings

Hi I have a Sealey Mightmig 150 which has 2 rocker switches marked 1 low 1 high 2 low 2 high no mention in instructions as to order, does anyone know if it is that order or 1 low 2 low 1 high 2 high if that makes sense.

Easiest way is to back off the wire feed, get a multi meter and meter (set on DCvolts) between the earth clamp and the tourch tip. As there does seam to be variations between machines of different vintage as to how the switches are set up.
