Bulk pack

From GAWDAwiki

In MIG welding, bulk pack is a packaging method whereby large quantities of continuous MIG wire can be supplied to enable robots or automatic welding machines to continue welding for long periods without interruption. The packs typically contain 200, 250 or 350 kg of wire, compared with the 15kg or so on a reel. ^[1]
