AFTEK EHS, a business group under Hotfoil-EHS, designs and manufactures electrical transformers used in heat treating, welding machines, power consoles, and other industrial applications. AFTEK transformers regulate amperage and voltage and convert the AC source to a suitable current for welding and heating.
AFTEK EHS manufactures Isolation Transformers from 10KVA up to 280KVA. We can supply any voltage input that is required and any voltage output that is required. These are hand-wound at our East State Street location where they are welded, dipped in varnish, and cooked in the oven. They are then labeled, serialized, 100% checked, and QA logged! All materials to create these transformers are 100% purchased in the USA, and the transformers themselves are proudly manufactured in the USA.
