AMADA – Transistor Welding Power Supplies

Features three types of control: constant current, constant voltage, and constant current and voltage

Features of Polarity switching type and Two-channel type

Key Features

• Fast rise time: AMADA Transistor-controlled welding power supplies have rise times 4.5 times faster than that of conventional* models. high quality welding can be accomplished in a short period of time on small work pieces. (*Compared with conventional model MD-1500E)
• No welding transformer needed: The welding current is directly controlled with fast switching by transistor, so no welding transformer is required.
• Built-in pre-check function: Applying current on the workpiece before the main current, it is possible to judge whether or not there is a workpiece set on the electrodes, and to evaluate the status of workpiece.
• Polarity switchable type: This can eliminate the Peltier effect (polarity effect) and provide uniform nugget diameters on series welding.
• Two-channel type: Two weld heads can be controlled by one power supply. It contributes to cost and space savings.
