Front Panel Controls
1) Power Indicator Lamp
This lamp is illuminated when the On-Off switch on the back
of your Invertig 160DC is turned to either the "220" position,
for operation on 220-volt power or the "110" position for
operation on 110-volt power.
2) Welding Current Indicator Lamp
When either the foot pedal or the trigger switch on the TIG
torch is depressed, welding current will be applied to the
welding torch and the Welding Current Indicator Lamp will
be illuminated.
If your Invertig 160DC is in the stick-welding mode, the
welding current indicator lamp will be illuminated all the
time.
3) Thermoswitch Indicator Lamp
The thermoswitch indicator lamp will light up when the duty
cycle of your Invertig 160DC has been exceeded. When this
lamp is illuminated, the machine will no longer weld because
the machine has overheated. Leave the machine plugged in
and turned on so the cooling
fan can cool the unit down. Allow the machine to cool for 15
to 30 minutes, the thermoswitch should reset automatically
and your Invertig will be ready to weld.
4) SLOPE DOWN or SPOT TIME
When the Welding mode is in the TIG 2T Mode, TIG 4T
Mode, or the PROGRAM Mode, this knob allows you to
adjust the slope down time from 0.3 sec to 6 sec. This is the
amount of time it will take for the welding amperage to go
from the welding amperage to the
final current.
NOTE: If you are using a torch mounted remote amperage
control or a foot pedal, it is advisable to set the slope down
time to 0.1 sec, as you are controlling the slope down
manually with your remote amperage control or foot pedal.
When the welding mode is in the TIG SPOT Mode this button
adjusts the spot welding time from 0.3 sec to 6 sec.
5) FINAL CURRENT
Rotating this knob allows you to adjust the Final Current.
This is only applicable when your Invertig 160DC is set in
the TIG 4T mode or the PROGRAM mode. The final
current is adjustable from 10% to 90% of the base current
that is set by the amperage adjustment knob (#8). For
example, if the amperage adjustment knob is set to 100
amps, and the final current is set to 15%, the final current
will be 15 amps.
