INDURO 145 OWNERS MANUAL
5. OPERATION
SAFE MODE
The Induro 145 incorporates a Voltage Reduction Device. This device is designed to
improve operator safety by reducing the voltage across the welding leads to a safe level
whenever the machine is not welding.
There are two safe modes:
•
Full safe
– the output drops to a safe voltage
0.2
seconds after welding stops.
The output then switches back to the welding voltage when the resistance from the
electrode to the workpiece falls below 200 ohms.
The Green VRD Safe LED is continuously lit to indicate when the unit is in Full Safe
mode.
•
Tack Weld Mode
– the output drops to a safe voltage
5
seconds after welding stops.
The output then switches back to the welding voltage when the resistance from the
electrode to the workpiece falls below 200 ohms. This mode should only be selected if
performing a series of short welds in succession, and difficulty is experienced in
starting the arc.
The Green VRD Safe LED blinks to indicate when the unit is in Tack Weld Mode.
This mode should only be selected when working in an “environment without
increased hazard of electric shock.” For further information, ref er WTIA Tech Note 7.
To select Tack Weld Mode, press the Weld Mode button three times immediately after
turning on the machine. The Induro defaults to Full Safe Mode each time it is switched on.
SLEEP MODE
The Induro 145 goes into “sleep mode” when not u sed for more than 10 minutes. This is a
low power consumption mode which includes shutting down the fan.
As soon as the operator attempts to strike an arc or if any button is pressed, the Induro
145 automatically “wakes up” in the mode in which it was last used.
Sleep mode is indicated by the currently selected weld mode LED blinking slowly, with all
other LEDs being off.
6. CONNECTION TO ELECTRICAL MAINS POWER SUPPLY
The INDURO 145 is supplied with a 15 Amp Heavy Duty mains power supply cable.
This cable must only be connected to a correctly installed 15 Amp GPO (General Purpose
Outlet). The plug and GPO are both identified by a wide Earth pin, which is intended to
prevent the plug being inserted into a standard 10 Amp GPO. If it becomes necessary to
replace the mains power supply cable, use only a cable with equivalent current rating.
The recommended Supply Circuit Breaker rating is 25 Amps.
If it is necessary to use an extension power supply cable, ensure that it is rated for a
minimum of 15 Amps. Voltage drop which will occur over long lengths of cable will reduce
the maximum welding current available from the equipment.
As noted previously, it is not recommended that the INDURO 145 be powered from
small engine-driven generator sets unless they have adequate voltage regulation due to
the peaks of supply voltage which can occur with some equipment of this type. Excessive
voltage peaks can damage the circuits of the welder.
