Bench AS333 for automatic TIG welding with or without filler wire longitudinal joints of thin-walled tubes

AS333 consists of:

- Frame;
- Mechanism of longitudinal moving of the torch;
- Tract;
- "Key row" mechanism of fixation of welding edges (pneumatic drive);
- Mechanisms of torch raising with a manual corrector of its position;
- Control system;
- Operator console;
- Set of welding equipment;
- Cooling system;
- Pneumoapparatus etc.

Technical dates:
Regulating range of welding current, A 8...160
Regulating range of welding speed, mm/s 3...30
Rated value of the torch path deflection, mm, at most ±0.2
Mechanisms drive of products edge-fixing and torch raising pneumatic
Protective gas     Ar
Air pressure, MPa, not less    0,4
Cooling of the torch and the pad liquid
Overall dimensions of the bench cell, mm 3000 x 2000 x 2500

AS333 peculiarities:
-Programmed control all mechanisms and devices of the machine, as well as diagnostics of their condition, is realized by a controller.
-Base program ensures: moving the torch in the welding start position, high-frequency starting of the arc, delay of moving the torch for shaping a puddle, moving the torch with necessary speed, crater welding, raising of the torch and returning it on march speed in the source position.
-Continuous adjustment of welding parameters;
-Quick bench readjustment to the welded of tubes with different lengths;
-There are versions of machine:
   - AS333-500 for tubes up to 500 mm long;
   - AS333-1250, AS333-1500 and AS333-2000 up to 1250, 1500 or 2000 mm long.
- The bench can be completed with cold wire feeder UP4 and programmer of seam length.
- This bench is an analogue of a bench AS308 for MIG/MAG welding of sidewalls from low-carbon steel.

Launching: about 150 benches in 2007 - 2020 at plants of Kiev, Moscow, St.Petersburg, Riga, Kharkov etc.
