Welding magnet with variable angle, Adjust-O, on/off, 50kg

Adjustable from 30 deg to 275 deg with two On/Off switches.
Machined flat surfaces and nickel/chrome body.
V-Groove surfaces securely hold round and square tubing, angle, and flat stock.

The correct usage of welding magnets is to hold the workpieces with them at the desired angle and tack it.
Then you must remove the magnets and, after that, start welding the joints.
Removing the welding magnets is important because they are sensitive to heat (they will start to lose strength) and can influence an electric arc.
