TK6400 is a series of high-power AC and DC fixed value resistive load boxes developed and designed by Tunkia. It can be used with TK6500/TK6700 welding machine calibrator to stabilize the power output of the welding machine and realize on-site calibration of the welding machine power.
☆ Calibrate the AC / DC Electric Welding Machine Power |
|
• TK6400 is used as a loop load for calibrating the power supply of the welding machine and consumes welding output power. It has two specifications of 200 A/ 600 A for option. |
☆ Type 200 A Load Box Front / Rear Panel | |
| |
Number | Function |
| Portable handles: one on each side for easy use when transporting the equipment. |
| Emergency Stop Button: when an accident occurs during the test, quickly stop the equipment and disconnect the circuit. |
| 200 A Current Terminal: used to connect the power output of the welding machine. |
| Rubber Braces: supports the device and provides shock absorption. |
| Power Socket and Power Switch: comes with a fuse. |
| Equipment Chassis Ground Terminal: used for grounding the equipment chassis. |
☆Type 600 A Load Box Front / Side Panel | |
| |
Number | Function |
| 600 A Current Terminal: available in common bolt terminal or quick connect terminal, used to connect the power output of the welding machine. |
| Pull rod: can be retracted, and can be used with wheels to drag the device to achieve rapid movement |
| Emergency Stop Button: when an accident occurs during the test, quickly stop the equipment and disconnect the circuit. |
| Equipment Chassis Ground Terminal: used for grounding the equipment chassis. |
| Wheels: Allows for easy movement of the device. |
| Power Socket and Power Switch: comes with a fuse. |
☆ On-site Portable Design |
|
• Considering on-site transportation, adopting a lightweight design solution with small size and light weight. • It can be quickly transported on-site through the handle and roller design of TK6400, saving user strength and improving work efficiency. |
☆ Cascading Capacity Expansion |
|
• Multiple TK6400s can be cascaded. For example, after cascading two TK6400-600 A models, they can be used as the output load of the 1200 A welding machine power supply to verify the source of a larger current. • Various combination methods can be flexibly matched according to user needs, and are suitable for power calibration of high-current welding machines of various specifications. |
☆ Convenient Optional Accessories | |
| |
• Common Bolt Terminal: requiring unscrewing the nut, putting on the current wire of the round hole wiring nose, and then tightening the nut to complete the wiring action. The operation is complicated and inefficient. | • Quick Connection Terminal: equipped with quick connectors suitable for various models. During operation, it only needs to be aligned and inserted and then rotated half a turn to lock, which is convenient and efficient. |
