What the QCW-150W is built to do
The QCW-150W is a qcw fiber welding source in the chain welding machines range. A 150 W QCW fiber source balancing speed and precision for chain welding.
An inline welding source sits alongside the chain machine and fuses every link as it is formed. Compared with a solder-powder joint, a welded link keeps the parent alloy at the joint, which matters for both strength and for colour matching on finished chain.
This unit delivers 15 J at 0.2–50 ms pulse with air cooling. The trade-off between YAG and QCW fiber sources — single-pulse energy against heat input and running cost — is covered in the gold chain production line guide.
Capability in practice
The figures below are the ones that decide whether this machine suits a given job. The full table is in the specifications section above.
| Parameter | QCW-150W | What it decides |
|---|---|---|
| Laser power | 150 W | Sets the section thickness that can be fused in a single pulse. |
| Pulse energy | 15 J | Energy per pulse decides how much section you can fuse in one shot. |
| Pulse frequency | 0.2–50 ms pulse | Higher rates suit continuous inline work; lower rates suit deeper single welds. |
| Cooling | Air cooling | Determines duty cycle and whether a separate chiller is needed on site. |
Where it fits in a workshop
The source is installed beside the chain machine and shares the line's duty cycle, so its cooling method and power draw matter as much as its pulse energy. It pairs with the chain making machines in the same range.
- Production line duty — continuous running as part of a chain cell.
- Findings assembly — welding clasps, jump rings, posts and bails.
Installation and site requirements
Most delayed commissionings come down to three things: the supply, the cooling and the route into the room. Check these against the site before the machine ships.
- Electrical supply — this machine expects AC 220±10% 50/60Hz. Confirm the socket, the breaker rating and whether the site is 50 Hz or 60 Hz.
- Power draw — 600 W. Size the circuit for continuous, not peak, operation.
- Cooling — Air cooling. No separate chiller position is required.
Operator handover covers the software, the parameter set for the specific alloy and wire in use, and the first production run. If any of the figures above sit close to your limits, say so on the quotation request and we will confirm before the order is placed.
