GTH 802 / GTH 1202, W 1005 VC welding rectifiers and transformer for submerged arc welding
Country: Germany · Model: GTH 802 / GTH 1202 / W 1005 VC
The GTH 802, GTH 1202 and the W 1005 VC transformer are high-power sources for submerged arc welding at 800, 1200 and 1000 A. The DC rectifiers work in mechanised, semi-automatic and automatic processes together with KA series machines. The AC transformer is intended for tandem and multi-arc welding.

Description
The GTH 802 works from 80 A / 18 V to 800 A / 44 V, gives 800 A / 44 V at a duty cycle of 80 % and 720 A / 44 V at 100 %. Supply 3/PE AC 400 V ±10 %, 50 Hz, power consumption at a 100 % duty cycle 44 kVA, time-delay fuse 63 A. The GTH 1202 covers the range from 100 A / 19 V to 1400 A / 44 V and gives 1200 A / 44 V at a 100 % duty cycle from the same mains, consuming 82.5 kVA. The W 1005 VC delivers sinusoidal alternating current from 200 A / 25 V to 1000 A / 44 V, with the full 1000 A at a 100 % duty cycle. Voltage and current are adjusted steplessly, and the CV/CC characteristics are switched internally or externally by software. Control is digital or analogue, with galvanically isolated signals for external control, for example by industrial robots. Dimensions 1130×750×990 mm, mass 510 kg, and the mains voltage of the transformer is not given in the data.
How to choose
The rectifier is selected for the wire of the machine. The GTH 802 is recommended for tractors and heads with wire up to 3 mm and current up to 800 A, the GTH 1202 for versions with wire up to 5 mm and parallel wire and current up to 1200 A. If several arcs are needed at the same time, the AC W 1005 VC is required. An inverter alternative is the KSI 700 at 40–750 A and the KSI 1000 at 80–1000 A.

FAQ
Which rectifier should be chosen for wire up to 3 mm?
The GTH 802, which gives up to 800 A. For wire up to 5 mm and parallel wire the GTH 1202 at 1200 A is needed.
What mains supply do the GTH 802 and GTH 1202 need?
3/PE AC 400 V ±10 %, 50 Hz. The GTH 802 takes 44 kVA and requires a 63 A fuse, the GTH 1202 takes 82.5 kVA.
What is the W 1005 VC transformer for?
For tandem and multi-arc submerged arc welding on alternating current up to 1000 A.
What are the dimensions and mass of the W 1005 VC?
1130×750×990 mm and 510 kg.
