Unitrol SOLUTIONi - HEAT SETTING MODES

FIRST TIME CONTROL SETUP
SECTION B, PAGE 21
B14. HEAT SETTING MODES:
Setting welding heat on your SOLUTIONi control can be done in two different
ways:
B14.1 UNDERSTANDING CONSTANT VOLTAGE MODE:
In this mode the welding heat will be set in % of the maximum available power
for the welding transformer and welder. In this case, the first display for a welding
schedule display will look like:
This CONSTANT VOLTAGE mode should be used for PROJECTION WELDING
(weld nuts, parts with projections). It can also be used for all welding sequences.
If you want to use only heat settings in percent
(%) and not use the CONSTANT CURRENT
feature of this control, exit out of this FIRST
TIME CONTROL SETUP section. You can
always come back at a later date to do this
procedure.
B14.2 UNDERSTANDING CONSTANT CURRENT MODE:
In this mode, the welding heat will be set in AMPS. This is useful if you are going
to use standard resistance welding charts, or are going to use the built-in RWMA
welding schedules. The CONSTANT CURRENT welding schedule display will look
like:
