KA 1-UP / KA 2-UP / KA 4-UPDG / KA 7-UPP welding tractors and heads for submerged arc welding
Country: Germany · Model: KA 1-UP / KA 2-UP / KA 4-UPDG / KA 7-UPP
KA series machines are self-propelled tractors and heads for mechanised submerged arc welding at 800–1200 A. The KA 1-UP runs a single-wire process, the KA 2-UP is mounted on gantries, columns and booms, the KA 4-UPDG welds two fillet welds at once, and the KA 7-UPP works with parallel wire. They are used for steel structures, beams, tanks, pressure vessels, pipes and in shipbuilding.

Description
The KA 1-UP is made in 3 mm versions (up to 800 A, wire 1.6–3.2 mm, 0.1–1.5 m/min, 57 kg, GTH 802 source) and 5 mm versions (up to 1200 A, wire 2.5–5.0 mm, 0.1–1.65 m/min, 66 kg, GTH 1202). The KA 2-UP head comes in 3 mm (800 A, solid wire 1.6–3 mm, 33 kg), 5 mm (1200 A, 2.4–5 mm, 40 kg) and KA 2-UPP for parallel wire (1200 A, 2×2.0–2×3.0 mm solid or 2×2.4 and 2×3.2 mm flux-cored, 42 kg). It is positioned manually by a cross slide with a 100 mm stroke on each axis, and there are automatic ignition and wire burn-back, a laser pointer and separate setting of start and crater filling. The KA 4-UPDG has two currents of 600 A, wire 1.6–2.5 mm per head (flux-cored up to 3.2 mm with two GTH 1202), speed 0.1–1.5 m/min, full drive, 78 kg, dimensions 955×950×1035 mm and 2×GTH 802 sources. The KA 7-UPP gives up to 1200 A, solid wire 2×2.0–2×3.0 mm, flux-cored 2×2.0, 2×2.4 or 2×3.2 mm, 0.1–1.5 m/min, 68 kg.
How to choose
The choice starts with wire diameter and current. Wire up to 3 mm and 800 A is covered by the KA 1-UP or KA 2-UP in the 3 mm version with the GTH 802, while wire up to 5 mm and 1200 A requires the 5 mm versions with the GTH 1202. The tractor travels along the workpiece itself, and the head is mounted on a fixed guide. For two opposite fillet welds in box sections take the KA 4-UPDG. KSI 700 and KSI 1000 inverters are also suitable as sources.
