SafeTac VRDT3 VRD Tester

The SafeTac VRD Tester Series 3 is a portable, programmable unit designed to test all current DC VRD welders on the market. It ensures safe and accurate verification of VRD on/off transition, even for machines that require higher loads.

Explorer Case Available

Key Features

• Tests all current DC VRD units.
• Internal 200Ω resistor with programmable microprocessor precision voltage indicator.
• LED indicators: Green (<35V) and Flashing Red (>36V).
• Works with wired TIG handpiece triggers and RF electrode holder switches.
• Auto power-down after 3 minutes to extend battery life.
• Adaptors included for all welding terminal types (Stud, Lincoln, Small/Large Dinse).
• Inline tester for safer, easier connections.
• Programmable to suit different voltage requirements.

Additional Information

• Some welders (Cigweld, Lincoln, Kemppi, SafeTac) need 30+ amps load for VRD switching.
• Testing is performed by welding at 90–150 amps for 2–3 seconds.
• Optional external load resistor allows non-welding testing.
