GUN SWITCH KEYS
IPM VOLTS KEY
Sets the gun thumbswitch to control IPM or VOLTS.
Pushing the gun thumbswitch forward (toward the tip)
increases and pulling it back decreases IPM or
VOLTS. The underlining cursor always indicates the
selection being controlled by the gun thumbswitch. If
the cursor is not present, the gun thumbswitch will not
be functional which prevents any inadvertent actua-
tions. Each time this key is pressed, it causes the cur-
sor to go to the next step in the following sequence
IPM to VOLTS to no cursor to IPM to VOLTS, etc.
NOTE: In Auto mode, changing IPM will change arc
voltage also and can cause a change in metal thick-
ness as well.

Auto screen is displayed prior to pressing IPM VOLTS
key. IPM VOLTS key is pressed, cursor moves from
under IPM to under VOLTS. Pressing the IPM VOLTS
key again causes the cursor to disappear. Pressing
the IPM VOLTS key again causes the cursor to
