Questions
IG-3/4 questions, answered
Straight answers from the people who install and service these machines. Anything not covered here, ask us on the form below.
Why choose induction melting over a torch?
Our catalogue describes induction melting as fast, clean, uniform and more controllable, capable of supporting purification stages and reducing heat-induced oxidation. In day-to-day terms: flameless and silent operation, reduced thermal shock, better productivity, and a bench an operator can work at for a full shift.
Do I need a water chiller with the IG-3/4?
Yes. Every induction model in the range is specified with a water chiller as its cooling system, and the stated machine weight includes it. Factor the chiller footprint into your layout before you commit to a position on the floor.
What supply does the IG-3/4 need?
The IG-3/4 is specified at Three phase 440V / 50Hz, 7 kW output. Confirm your incoming supply before selecting a capacity band - moving between single and three phase after the machine is built is the single most expensive change a buyer makes in this category.
What power supply does the IG-3/4 need?
Rated power is 7 kW. It runs on Three phase 440V / 50Hz. 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.
How much floor space does the IG-3/4 need?
It weighs 150 kg. Allow clear working space on the operator side, plus access for any support equipment — compressor, air dryer or water chiller — when planning your layout.
Does the IG-3/4 come with installation and training?
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.
What is the delivery time, and how are spare parts handled?
We do not publish delivery times, spare-parts pricing or AMC terms, because all three depend on configuration, destination and what is on the floor at the time.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.
What does the IG-3/4 cost?
The IG-3/4 is quoted to your configuration, quantity and delivery location. Send us your requirement through the form on this page, or message or call our sales team, and you will receive a written quotation.
