| 1、Application |
T2200 is the latest product of Shanghai Medar. It has the advantage of both of the 200Sand 3000S. It can use both AVC or ACC mode. which is particularly useful to the coated steel plate. All parameters such as welding specification and data, error and fault code, C factor, network voltage, weld current, can be displayed timely on screen so that it is easy for operation, maintenance and test. By separating control, firing and I/O functions in three different boards makes maintenance much more efficient and easier, and the cost will greatly reduce. All the PC boards, connectors, firing cable are imported from WTC (U.S.A.). The control can conform with Standards and Regulations such as NEMA electrical, NEC, UL and CSA. |

| 2、Characteristics |
1) Up to 63 different parameters able to be set to satisfy a variety of welding conditions.
2) 2 pilot inputs assigned to 2 weld valves.
3) Automatic Voltage Compensation which monitors primary voltage using a programmable nominal voltage reference point.
4) Automatic Current Compensation which monitors the current during each cycle and compensates during the next cycle for any change detected.
5) 3 weld features-Preweld, Weld, Postweld.
6) 2 line 40 character LCD display provides status messages and prompts to guide you through programming talks. Upper line is the weld sequence information. Lower line is the weld data including lowest line voltage, welding current, computed power factor of the last weld, and fault status.
7) 2 steppers each containing 5 steps to compensate electrode mushrooming, status are also displayed after the weld data.
8) Complete diagnostics to include error messages and fault/alert output. A number of setup parameters can be programmed either as ALERT or FAULT. When a FAULT is detected, it will stop further initiations until the faults have been reset.
9) To monitor 128 welders at the same time with PC.
10)By separating control, firing and I/O functions in three different boards makes maintenance more efficient and easier to reduce cost.
11)C factor can monitor change in contact resistance, cable deterioration, electrode mushrooming in secondary circuit.
12) Function of net work system, tipdress, safety control, pilot start sequence, chain and successive schedule, setting parameters for weld limit and also can be used in robot.
13) Able to control analog value for proportional valves. |
