Innershield welding.

(based on a 10 minute cycle). It is also rated at 275
amps, 100% duty cycle.
OPERATIONAL FEATURES and CONTROLS:
UPPER CONTROL PANEL
1. AMPS Meter
• Prior to STICK operation (current flow), the meter
displays preset current value (either 2 amps or +/-
3% (e.g. 3 amps on 100), whichever is greater).
• Prior to CV operation, the meter displays four dash-
es indicating non-presettable AMPS.
• During welding, this meter displays actual average
amps.
• After welding, the meter holds the actual current
value for 5 seconds. Output adjustment while in the
"hold" period results in the "prior to operation" char-
acteristics stated above. The displays blink indicat-
ing that the machine is in the "Hold" period.
2. VOLT METER
• Prior to CV operation (current flow), the meter dis-
plays desired preset voltage value (+/- .5V).
• Prior to STICK operation, the meter displays the
Open Circuit Voltage of the Power Source or four
dashes if the output has not been turned on.
• During welding, this meter displays actual average
volts.
• After welding, the meter holds the actual voltage
value for 5 seconds. The displays blink indicating
that the machine is in the "Hold" period.
• Output adjustment while in the "hold" period results
in the "prior to operation" characteristics stated
above.
3. OUTPUT CONTROL
• Output control is conducted via a single turn poten-
tiometer.
• Adjustment is indicated by the meters as stated
above.
4. WELD TERMINALS-REMOTE / ON
• Two status lights indicate the location of trigger con-
trol as determined by the "WELD TERMINALS"
push button.
• If trigger control is local "weld terminals on", the ON
display will be lit.
• If trigger control is remote "weld terminals remotely
controlled", the REMOTE display will be lit.
• The unit will power up in "pre-determined preferred"
trigger modes.
STICK = ON
CV = ON or REMOTE depending if remote output
controls are connected to the machine.
These trigger modes can be over-ridden (switched) with the
WELD TERMINALS push button. When changed, the unit
will power up in the configuration it was in when it was last
powered down.
