Product Details
Ask any welder what ruins a joint: the workpiece that shifted a millimetre at the wrong moment. Magnetic welding clamps solve the hardest part of the job — positioning — by holding the pieces exactly where you set them, so both hands stay free for the torch and one person can do what used to take two.
PML Multi-Angle Magnetic Welding Clamps are built for fast, accurate welding and soldering of small sheets and tubes:
- Five Working Angles
Holds workpieces at 30°, 45°, 60°, 75° and 90° — the geometry of the clamp sets the joint angle for you.
- Hands-Free Accuracy
Frees both hands, making the welding job easier, faster and more accurate.
- Grips Any Ferrous Surface
Sticks instantly to any ferrous metal object — no mechanical clamping, no marks.

Frequently Asked Questions
Will the clamp hold during tack welding?
Yes — that is exactly what it is for. Set the pieces at the required angle, and the magnetic grip keeps them in position through tack-up and finish welding. Holding forces per model are listed in the specification tables above.
Which model do I need?
Standard multi-angle clamps cover 30–90° inside work; the 632 works from the outside of the corner; the 634 gives adjustable corner angles. Compare the tables above, or ask our team.
Does welding heat damage the magnet?
The clamps are designed for welding environments — observe the maximum operating temperature listed for each model in its specification table, and keep the clamp out of the direct arc.
