Magnetic Controlled Automatic Welding Trolley for Carbon Steel Fabrication

When you’re laying down long horizontal fillet welds on heavy steel plate for a bridge girder or ship hull, this trolley basically handles teh travel while you keep an eye on the puddle, and it’s a lot less fatiguing than crouching behind a hand carriage all shift.

It runs off standdard 220V AC, weighs 7.5kg, and measures 300×230×280mm so you can lug it up a ladder or toss it in a truck bed without a second thought—the four rubber wheels and permanent magnet keep tracking stable even if the suface is a little oily or rusty.

Walking speed is fully adjustable form zero up to 99 cm/min, and the LED display shows you exactly where you’re set, but that ±45° operating angle and ±20mm vertical/horizontal adjustment range (plus the ±10° welding angle) means you can dial in the gun position for tight corners or sloped sections without wrestling the whole unit.

One thing we don’t recommend it for is vertical-up welding on thin-wall pipe—the magnet pull is strong enough to hold on 8mm plate, but on lighter sections you’ll get a nasty arc blow that messes with penetration and bead shape.

Also, the X-Y slider and clamp are alumnum alloy, so they’re light and corrosion-resistant, but be careful torquing the locking knobs because threads can gall if you overdo it—we usually have stock on the 220V model, but confirm lead time if you need a 110V variant.

Most buyers just grab the CE-compliant unit and a spare set of rubber wheels (roughly 50 units or so per batch), and we’ll ship with a standard COA and the manual.
