About These Guides
Where does the information in these guides come from
From SGT's own published specifications, capacity tables, comparison charts and validation data for the machines, dies and consumables described. Where a figure is not published it is marked TBC rather than estimated.
Which guide should we read first
If you are choosing a machine, start with Selecting a Cold Welder by Wire Diameter. If you are choosing dies, start with Choosing Between Tungsten Carbide PCD and Nano Drawing Dies.
Can we get these as PDFs
The capacity chart, the die matching chart and the full product catalogue are in the Download Center as PDFs. The guides themselves are web pages so they stay current.
Can you advise on our specific line
Yes. Send the wire materials and diameters, the machines already installed and the country. That is enough to name the models and the die programme.
Ask a Question the Guides Do Not Answer
The sales desk answers technical questions directly. Send the wire size and the machine and you will get a specific answer, not a brochure.
