SafeTac VRDT2 VRD Tester

SafeTac VRD Tester (Series 2)

VRD Tester is a test unit designed to operate with all SafeTac VRD units. It is a cylindrical rod with a green or red button one end and a brass lug on the other.

With a brass button in the middle, testing is accomplished by touching the brass end onto the work clamp then placing the electrode onto the central brass button and pressing the test button. Upper test resistance has been increased from 180 Ohms to 200 Ohms +/- 1% (1674.2 2003) VRD turn on point and 33 ohms VRD turn off point. The series 2 tester now works with Cigweld and Eutectic VRD products plus many other Factory VRD units set close to the 200 Ohm maximum resistance VRD turn on point.

At no time is the operator in contact with the welder output whilst testing.

Note: Keeps test’s short as possible to prevent overheating.
