ARCCAPTAIN welding magnets are arrow-style magnetic holders that hold ferrous steel at 45, 90 and 135 degree angles while you fit and tack. The listing gives a holding power of up to 25 lb. They help with hands-free alignment of small frames, brackets and sheet metal, but they only grip magnetic steel and are not a substitute for clamps on heavy or load-bearing work.
Quick Verdict
A handy, inexpensive setup aid for steel fabrication in a garage. Skip them if you mainly weld aluminum, copper or brass, or if you need rated clamping force. Confirm the pack quantity, dimensions and warranty on the listing, since those are not confirmed here.

Who It Is For
- DIY welders who need to hold steel at 45, 90 or 135 degrees.
- Garage fabricators working on small frames, brackets, sheet metal or pipe layouts.
- Anyone who wants both hands free while checking the fit before tacking.
Who Should Skip It
- You mainly weld aluminum, copper, brass or non-magnetic stainless.
- You need a rated clamp for heavy, overhead or load-bearing positioning.
- You need confirmed dimensions, weight or warranty before buying.
How to Use Welding Magnets
- Wipe the magnet faces and the steel. Grinding dust, paint chips and oil reduce grip.
- Place the first piece, bring the second against the magnet and check the angle with a square or tape.
- Tack the joint, then remove the magnet so heat and spatter do not damage it.
- Add clamps if the piece is heavy, round or likely to shift.
Round stock gives less contact than flat plate, so grip varies. Keep fingers clear when the magnet snaps onto steel.
Safety Notes
- Do not use the magnets to lift material or support parts overhead.
- Keep strong magnets away from pacemakers, phones, cards and magnetic storage media.
- Clean with a damp cloth and mild detergent, then dry. Avoid abrasives.

Is It Worth Buying?
For routine steel projects they speed up setup. Compared with a plain 90-degree welding square they add two more angles; compared with clamps they are faster but hold less firmly.

Frequently Asked Questions
Can ARCCAPTAIN welding magnets hold aluminum or copper?
No. They need ferrous metal to grip, so they will not hold aluminum, copper, brass or non-magnetic stainless steel.
Is 25 lb the weight or the holding power?
The listing gives 25 lb as holding power, not the weight of the magnet. Real grip depends on thickness, surface condition and contact area.
What angles do they support?
45, 90 and 135 degrees. The 90 degree face squares corners, and the other two help with angled joints.
Can they replace welding clamps?
No. Use them to position parts and use clamps, stands or fixtures when the work is heavy, overhead or likely to shift.
Are they safe near electronics?
Keep them away from pacemakers, phones and magnetic storage media, because strong magnets can interfere with some devices.
Final Verdict
ARCCAPTAIN welding magnets are a practical, low-cost angle-holding aid for steel fabrication. Treat them as an alignment helper, not as a clamp, and check pack contents on the listing.
