Product Details
Most fabrication is 90° work — and every degree of error multiplies down the assembly. The PML Fixed 90° Magnetic Welding Clamp is the fastest, easiest, most hassle-free way to weld items at a true right angle: set the pieces against the clamp, and the magnet holds them square while you weld hands-free.
- A True 90°, Every Time
The fixed geometry guarantees the right angle — no measuring, no re-checking.
- Rods, Pipes and Sheets
One clamp positions all the common workpiece shapes.
- 25 kg Holding Force
Firm grip through tack-up and finish weld, at a unit weight of just 1 kg.
- Welding-Environment Tough
Operates in temperatures up to 250°C.

Frequently Asked Questions
How much weight will it hold at 90°?
The Fixed 90° clamp holds up to 25 kg — ample for the rods, pipes and sheets it is designed to position. The mini square models' holding forces are in their specification tables above.
Is it affected by welding heat?
It operates up to 250°C. Keep it out of the direct arc and clean spatter off the faces to preserve grip.
What is the difference between the 631 and 633?
Both are compact square clamps; the 631 covers 45° and 90°, while the 633 adds a 30° working face.
