WIA 16TC40 Welding Rods Overview
Table of Contents
A true dependable workhorse - the WIA 16TC 4.0 mm Low-Hydrogen Welding Rod (5 kg pack). Whether you’re battling pinholes, flickering arcs or beads that resemble cratered moons, this rod has your back.
A little about the brand. Why WIA Matters
Welding Industries of Australia (WIA) began in Melbourne in 1962, specialising in electrodes tuned for Australia’s fickle rural power. Today, it sits under the Illinois Tool Works umbrella—alongside Miller, Hobart, and Bernard—backed by a Fortune 200 support network and 60+ years of welding know-how.
They know their stuff.

My Top Workshop Tips
- Pre-heat Thick Sections. 100–150 °C avoids cold-cracking.
- Keep ’Em Dry. Store in a rod oven or dry cabinet—moisture is hydrogen’s best mate.
- Dial in Your Amps. Start at 140–150 A for 4 mm rods; tweak ± 10 A based on fit-up and joint prep.
The Bottom Line
The WIA 16TC 4.0 mm Low-Hydrogen Welding Rod is hard to beat for rock-solid structural steel welds with minimal hydrogen headaches. It quietly gets the job done—so you can wrap up on time, head home and maybe sneak in a cheeky post-shift beer. You deserve it for being so smart.
