Operation.
Current N.A.T.A. Calibration certificate included.
Test Welding Machine Peak OCV with Peak OCV tester before below test to ensure compliance
To Australian Standards Peak output OCV 35 VDC or less
Ensure Welding Plant is turned off before any connections or disconnection is made.
1. Connect Earth clamp & Electrode holder to VRDT5 tester Polarity is not important.
2. Connect Input leads to Welding Machine Polarity is not important
3. Start or turn on welding machine & set to MMA or stick position set current to approximately 90 Amps.
4. Ensure 200 Ohm switch is in off position VRDT5 should turn on automatically if not press green power
button to turn on.
5. Ensure screen is in OCV weld to test mode ,Weld then when siren beeps then stop welding OCV will be
indicated on screen & green LED should be on if red led is on then VRD OCV test has failed.
6. If test was OK press program button to change to Time test mode plus turn 200 OHM switch to the on
position LED should be green if it changes to red when the switch is turned on then the VRD is operating
at above 200 Ohms & needs attention.
7. If LED is green then weld until beeper sounds then stop welders VRD turn on time should be displayed
on the screen ,Green led should be on if red is on & flashing then VRD has locked on & needs attention.
