We’ve been getting RFQs for a 500-amp gas torch continuous heavy plate work, and the BW500A is what we’re quoting for that. It’ll handle CO2 at 500A or mixed gases at 400A, and the 60% duty cycle means you can run it hard on a production line without overheating—we’ve had shops push it on 15mm-plus steel for full shifts.
Teh E-Cu construction is basically pure electrolytic copper in the contact tip and neck, which gives you better thermal conductivity than brass alloys. It’s Tweco American style compatible, so you’ll swap it onto existing feeders without adapter plates. Wire size range is 0.9mm to 2.4mm, and that’s pretty standdard for MIG or flux-cored on structrual work.
One thing buyers sometimes ask about is flame control—it’s adjustable, but it’s a gas valve adjustment, not a digital regulator. For industrial welding that’s actually fine, because you’re setting flow by feel and the torch holds it steady. It’s not suited for precision TIG or thin sheet below 3mm, the amp range is too high for that.
Cable lengths are 3m, 4m, or 5m—we usually stock the 4m most, but confirm lead time if you need the 5m, as that can take 20 days or so. The ergonomic handle is rubberized and grips well even with gloves, and it stays cool enough during a long weld pass. CE and ISO9001 certs are on file, and our company provide a COA with each unit.
400A on mixed gas is a tighter tolerance than most off-the-shelf torches, so it works better for shops running argon-CO2 blends on heavy plate. Duty cycle at 500A is 60%, but if you drop to 400A it’ll run 80% or so. We’ve seen it used mostly in shipyards and presure vessel fabrication.
It's CE and ISO9001 certified, so you get the quality docs needed for most industrial compliance checks.
Yes, it's designed specifically for Tweco American style connections, so it'll swap right in without adapters.
Our MOQ is typically 50 units per model, but we can discuss smaller trial orders depending on stock.
We offer standard lengths of 3m, 4m, and 5m. Custom lengths may be possible for larger orders—just ask.
It works with wire sizes from 0.9mm up to 2.4mm, so it covers a solid range for most industrial welding jobs.
