A-550 type automatic welder for electroslag welding is designed for one-pass electroslag welding of metals from 50 mm to 450 mm in thickness. The DC welding is done with simultaneous use of one, two or three electrodes with double-sided forced seam forming.

Under special order:

-         the automatic welder can be manufactured for voltage of 380, 415V and frequency of 50 Hz;

-         vertical stroke of the welder is set depending on the height of article to be welded.

The welder is designed for the following type of welded joints:

-         longitudinal butt seams from 50mm to 450 mm in thickness.

-         ring seams in outer diameter up to 3000mm at wall thickness from 50mm to 450mm.

Features of A-550:

-        welding control is performed by the controller;

-         stepless regulation of welding and travel speed;

-         the automatic welder is equipped with emergency control system of welding process (welding wire feed, cooling liquid, air pressure, short circuit, failure in work of oscillation) with audiovisual warning.

-        independent separate control of welding rectifiers;

-        the welder has stepless regulation and digital data display of welding modes (current, voltage, feed speed, travel speed);  

-         data entry from operator’s panels mounted on the welding head and control panel;

-         the welder is equipped with video camera tracing the process taking place in welding pool,  with display on LCD panel;

-         all cables in the welder are guarded in the boxes and laid in the wire-laying track in flexible places;

-        being on the movable platform operator can watch and control the welding process. He can go up with the welding head;

-         being outside the welder operator can watch and control the welding process using the remote control;

-         control cabinet with forced ventilation and interior lightning, with audio security control system;  

-        braking mechanisms with bobbins that allows of spooling the wire up to 100 kg.

Features of welding head:

-         stepless regulation of welding wire feed speed;

-         stepped regulation of mechanism of electrode oscillation;

-         pneumatic clamp of rear slider with a possibility of manual clamp;

-         4 roller straightening – clamping mechanisms;

-         manual vertical adjustment of the wire feed mechanisms;

-         separate feed of welding wire into the weld zone;

-        manual longitudinal and horizontal adjustment of the welding electrodes for the welding wire feed;

-         possibility of time delay of welding electrodes in the weld zone at oscillating process;

-        installation of 3 standard bobbins with wire (up to 30 kg each) on the braking mechanisms on the movable platform;

-         cooled copper sliders provide the forced weld forming with strengthening as well as good weld forming at the shift of product’s edges up to 8mm.
