Weld Tester

Weld Tester Hook for eRex – A compact 60 g hook-style electrode (185 × 110 × 25 mm) that snaps onto the eRex via its built-in magnetic connector, letting you glide along thermoplastic or bitumen seams and probe tight corners without losing contact. Ideal for quick, one-handed verification of critical welds where the standard T-electrode cannot reach, this accessory keeps the arc steady so flaws show up instantly while adding virtually no bulk to your field kit.

Weld Tester Hook for eRex – product overview

The Weld Tester Hook is a slim, hook-shaped electrode designed specifically for inspecting welded seams with the eRex arc-tester. A curved conductive tip slides smoothly along the fusion bead and into tight overlaps, giving the instrument constant electrical contact where the standard flat T-electrode may lift away. The hook snaps onto the eRex via the tool-free magnetic connector used by all eRex accessories, so preparation takes seconds and one-handed operation is easy even on vertical joints. Because every millimetre of the seam remains under test current, pinholes or incomplete fusion trigger the eRex’s visual and acoustic alarms immediately, helping crews certify weld integrity before the waterproofing layer is covered.
