From order to production
How an installation works
-
We check your site before dispatch
Tell us your incoming power supply, the floor or bench space and, for a setting machine, your compressor and air dryer. We confirm they suit the machine before it leaves us.
-
Our engineer installs the machine
The machine is set up and run at your premises, not handed over in a crate. On a Signet analyzer that includes the software on your computer.
-
Your operators are trained on it
Training happens at the same visit, on your own work: your wax and stones on a setting machine, your own samples on a Signet FSDD.
-
Support after handover
Call or WhatsApp sales with the model and a photo or short video of what the machine is doing. It is the fastest way for us to diagnose it.
Talk to someone who knows the machines
Tell us what you produce. We reply within one working day with a recommendation, a demonstration or a written quotation.
Before the engineer arrives
What to have ready
- Pro Mini: single-phase 220 V power (1.3 kW) and compressed air at 80 psi (0.4 MPa)
- X4 Pro Plus: single-phase 220 V 50 Hz power, 3 kVA peak, and floor space for 950 × 750 mm
- ST-HDSSM: AC 220 V 50 Hz (3.5 kW) and compressed air at 90 psi (0.6 MPa)
- Every setting machine: a compressor and an air dryer, because moisture in the line causes nozzle problems
- Signet FSDD: a sturdy bench for 615 × 418 × 315 mm and about 40 kg, plus room for its computer
- Your operators free for the training session, with the wax, stones or samples they work on daily

Questions
Installation and service questions
How to reach sales, wholesale and support is on contact.
Is installation included when I buy a Semsons Tech machine?
For the X4 Pro Plus and Pro Mini setting machines, our store sheets state that on-site installation and operator training are included. The Signet FSDD, Si-Pin and Signet-PC XRF analyzers are also installed on site with operator training. The portable gold tester and the gold coin tester need no installation visit. For every other machine, what the installation covers is written on your quotation.
What warranty do Semsons Tech machines carry?
It depends on the machine. The X4 Pro Plus and Pro Mini store sheets state a 12-month warranty, extendable with an AMC, and that applies to those two machines only. For every other machine the warranty is stated in writing on your quotation, so ask for it there before you book.
Is operator training included?
Yes, where the machine is installed on site: our engineer trains your operators at the installation visit. On the Signet FSDD the training is done on your own samples, and the Pro Mini store sheet says an operator learns it in about one hour.
What do I need ready before the installation visit?
The incoming power supply, the floor or bench space and, for a wax setting machine, a compressor with an air dryer: 80 psi (0.4 MPa) on the Pro Mini and 90 psi (0.6 MPa) on the ST-HDSSM. A Signet FSDD needs a sturdy bench for its 40 kg body and room for the computer that runs it. Tell us what you have and we confirm it before dispatch.
Which suction nozzle do I need for my stone size?
Nozzle 502 for 0.8–0.9 mm stones, 502B for 1.0–1.2 mm, 503 for 1.3–1.4 mm, 503B for 1.5–1.9 mm and 504 for 2.0–3.0 mm, each with its matching sorting tray. Send us your machine model and stone size and we confirm the part before dispatch.
Do buyers outside India get the same warranty and service?
Yes. Buyers outside India get the same warranty, installation, operator training and after-sales service as buyers in India. See our international buyers page for how export orders work.
Can I extend the warranty or take an AMC?
The X4 Pro Plus and Pro Mini warranties are stated as extendable with an AMC. The AMC terms and price, and whether an extension is offered on other machines, are given in writing on your quotation.
