A Stud Every Few Seconds. Not a Mark on the Other Side.
The CRUXWELD CDS10M is a capacitor discharge stud welder: it stores 2500 joules in a capacitor bank and fires it through the stud tip in 1–3 milliseconds — fast enough to fuse M3–M10 studs to steel, stainless, aluminium or brass sheet before the heat can reach the show face.

Fix Studs to Thin Sheet Without Touching the Show Face
Drilling, tapping, riveting or spot-welding a nut all leave a hole, a dimple or a burn on the far side of the sheet. On a painted enclosure, a polished kitchen panel or a signage letter, that is a reject.
The CDS10M welds the stud from one side only. The operator loads a stud in the gun, presses it against the sheet and pulls the trigger. The capacitor bank discharges through the small tip on the stud face; the tip vaporises, an arc melts the whole face, and the gun spring plunges the stud into the pool. The joint is solid before heat can travel through the sheet.

20% charge · How it works
Charge, Touch, Fire — the Whole Weld Takes Milliseconds
1
Charge
The 141,000 µF capacitor bank charges to the voltage set on the dial (30–200 V DC) in under 3 seconds. The display shows the charge.
2
Load and touch
Push a stud into the collet, set the gun square on the sheet and let the stud’s ignition tip rest on the surface.
3
Fire
On the trigger the stored 2500 J releases in 1–3 ms. The tip vaporises, the arc melts the full stud face and a thin skin of sheet.
4
Plunge and repeat
The gun spring drives the stud into the pool and the joint freezes. The bank is charged again before the next stud is loaded.
A copper collet per stud size grips the stud; the slotted end is adjusted so the ignition tip just touches the sheet.
Tripod legs
Three legs hold the gun square to the surface, so every stud stands straight.
Pressure knob
Sets the spring force that plunges the stud into the weld pool; the indicator shows the setting.
Trigger
One pull fires the discharge. The control lead carries the signal back to the power source.
New stud size? Four settings.Fit the matching collet, adjust it so the ignition tip just touches the sheet, set the spring pressure on the knob (the indicator shows it), then bend-test the first stud. Set the charging voltage on the dial for the stud size and material.

Bend It. It Should Not Break at the Weld.
Good weldThe stud bends over without cracking at the base: voltage, spring pressure and tip setting are right for the sheet.
Snaps off at the baseRaise the voltage or clean the sheet, then test again.
Stud leansCheck that the tripod legs sit flat and the gun is square to the surface.
Tap a result to see what it means. Illustration.
The first stud of every batch is bend-tested with a spanner or tube. A good CD weld bends the stud over without cracking at the base: the fused face is wider and stronger than the stud itself. That one test tells the operator the voltage, spring pressure and tip setting are right for the sheet.
✓Stud bends, weld holds: settings are correct
✓Stud snaps off at the base: raise the voltage or clean the sheet
✓Stud leans: check the tripod legs sit flat and the gun is square

Price, power, limits, delivery and spares — answered before you ask.
1
PriceThe CDS10M price depends on the collet set you need (M3 to M10), the gun and tripod configuration, extra collets for a second stud size, and quantity.
2
Power220 V single phase, 50/60 Hz, input power up to 0.8 kW. It runs from a normal workshop socket, so no three-phase connection is required.
3
LimitsContact-mode capacitor discharge welding for M3–M10 studs in mild steel, stainless steel, aluminium and brass on thin sheet. For larger studs and heavier plate choose the drawn-arc stud welder.
4
DeliveryDelivery time depends on current stock and the collet set and is confirmed with the quotation. Every machine is tested before dispatch.

A machine that stores energy in a capacitor bank and releases it through the tip of a stud in a few milliseconds, fusing the stud to sheet metal from one side. The CRUXWELD CDS10M stores 2500 J and welds M3–M10 studs in 1–3 ms.
Will the weld show on the other side of the sheet?
No. The weld is over before heat can travel through the sheet, so painted, polished and stainless show faces stay clean. That is the main reason to choose CD over drilling, riveting or spot-welding a nut.
Which stud sizes and metals does it weld?
M3 to M10 studs, pins and tapped bosses in mild steel, stainless steel, aluminium and brass, on sheet of the matching metal. A copper collet is used for each stud size.
What power supply does it need?
An ordinary 220 V, 50/60 Hz single-phase socket. It draws under 0.8 kW.
How fast is it?
The bank recharges in under 3 seconds, giving 10–25 studs a minute depending on the stud size and the operator.
How do I set it up for a new stud?
Set the charging voltage on the dial for the stud size and material, fit the matching collet, adjust the collet so the ignition tip just touches the sheet, set the spring pressure, then bend-test the first stud.
What is supplied with the machine?
The CDS10M power source, the stud gun with weld and control cables, an earth cable with clamp, collets for the sizes on your order and the mains cable. Your quotation lists the exact scope.
How do I get the CDS10M price and delivery time?

Just bought a CDS12M for reselling in North America, accommodation and shipping was impressive, thanks to good pre-sales team.
We are ready to experiment the After sales service, we’ll keep you posted.
We bought our 1st unit CDS12M, good looking machine.
Unless we receive a North American power supply soon we’ll have to return the equipment.
