Pulling gun thumb switch back decreas- es IPM or VOLTS. The underlining cursor always indicates the selection being controlled by the gun thumb switch. See Figure B.4.
If the cursor is not present, the gun thumb switch does not function. This prevents any inadvertent actuations. Each time this IPM VOLTS key is pressed, the cursor moves in the following sequence: IPM to VOLTS to no cursor. The sequence continues each time the key is pressed.
NOTE: In Auto Mode, changing IPM changes arc volt- age. This can result in a change in metal thickness setting as well.
