C.     Technical Function Views on Welding Positioner and its Welding Turning Table:

1.       Safety Assurance on Rotary Welding Table Revolving, Tilting and Elevation:

Safety is the first issue which should be considered and guaranteed for developing any kind Welding Positioner. For this purpose:

1)       Driving motors of rotary welding table for revolving and tilting are all braking type;

2)       For Wuxi JACK Elevating L type Welding Positioner, hydraulic oil cylinders are adopted for driving elevation of its rotary welding table, instead of ordinary motors selected by some other suppliers; (Fig.9)

3) There are hard stops equipped in all motions of rotary welding table: Revolving, Tilting and Elevation;

2.       Welding Speed of Welding Positioner:

1)       Revolving linear velocity of Welding Turning Table is welding speed in all categories of Welding Positioner;

2)       This speed is controlled with A.C. inverter, to realize stepless continuous change, and displayed in digital display meter;

3) Adjustment on welding speed is convenient: Just turn the speed knob on the operating pendant of Welding Positioner, which is installed along side the digital display meter; (Fig.10)
