The focal spot diameter is reproduced above exactly as printed in our catalogue ("0.2-3.0 nm"). We believe this reflects a catalogue typesetting convention rather than the intended engineering unit, and we would rather flag that openly than silently correct our own source. Confirm this parameter against the manufacturer datasheet before procurement.
Production repair and fabrication where welds must be placed close to set stones and finished surfaces without the heat spread of torch work.
Send us your designs and target output. We will tell you honestly whether this machine, a smaller one, or a larger one fits — including when the answer is "you don't need this yet".

Answers
That is the main reason to own one. The pulse is focused and short - 0.1 to 20 ms at an adjustable focal spot - so heat is delivered locally instead of spreading across the piece the way a torch does. Combined with 10x microscope and CCD viewing you can place a weld precisely where it is needed. Stone type and proximity still matter, so we set the machine up on your actual work during commissioning.
Pulse ramping shapes how power is delivered across the pulse rather than dumping it all at once. In practice it gives cleaner welds with less spatter and less cracking on sensitive alloys - one of the catalogue-listed features alongside sweet spot, speed mode and micro weld.
No. The catalogue specifies a chiller and wind cooling system built into the machine, which is what lets it hold output through a production shift rather than needing to rest between welds.
No. In our range the jewellery spot welding machine is a laser machine - the "spot" refers to the small, localised weld it produces. Tick welding and hydra welding are separate resistance processes, listed separately at stage eight of the factory workflow.
Rated power is 200 W. Confirm your incoming supply before you order — voltage and phase are the two things that most often need changing after a machine has already been built.
Yes. We commission the machine on your floor and train your operators on your own material and your own designs rather than a demonstration sample. Semsons Tech has served the diamond and jewellery industry since 1978, and on our setting machines the control system is self-developed, so support does not depend on a third party abroad.
We do not publish delivery times, spare-parts pricing or AMC terms, because all three depend on configuration, destination and what is on the floor at the time. They are confirmed in writing on your quotation rather than estimated here. Ask for them explicitly when you enquire and you will get them in writing.
We quote per configuration and destination rather than publishing a list price, because voltage, tooling, spares package and shipping all change the figure. Send us your requirement through the form on this page and you will receive a written quotation.
