The IPB-5000B-MU inverter spot welder delivers superior welding control for a wide range of microjoining applications. When paired with the ITB-780A6 transformer this unit is capable of a maximum output of 6000 Amps, making it ideal for most resistive and conductive welding applications. It operates in constant current, voltage or power feedback modes and is also capable of welding in a combo mode (current and voltage) to address even the most challenging application or process conditions.

Key Features

• Control Modes – Optimum control modes for obtaining ideal weld quality and consistency can be chosen from; constant current control, constant voltage control, combination of constant current and constant voltage control, and constant power control.

• GOOD/NO GOOD determination – The comparator feature allows to set upper and lower limits around the measured value of up to four parameters; which are current, voltage, power and resistance. When those values reach out of the limits, an error signal or a caution signal alarms.

• Diplacement Measurement – Measures how much an electrode moves down because of material collapse during weld. Weld to displacement – stops welding when displacement value reaches the set value. Requires displacement sensor sold separately.

• Envelope – The envelope feature allows dynamic limits to be set around a monitored waveform to ensure the same resistance change occurs at the same rate for every weld.

Transistor direct current power supplies (also called “Linear DC”) produce much the same results as the high frequency inverter by using a high number of power transistors as the direct energy source. This technology provides clean, square wave forms with extremely fast rise time. Used primarily in constant voltage feedback control, transistor DC power supplies are effective in thin foils and fine wire welding applications and for extremely short welds.

The UB-4000A Linear DC welding control is ideal for applications which require exceptional control, fast rise times, and high quality throughput. UB-4000A requires only single phase input power and can output up to 4000 amps. Ultra-fast rise times permit short overall weld times, resulting in less part deformation and stronger welds. This is extremely important when welding heat sensitive parts such as battery cells or sensitive electronic devices.

UB-500A (5-500 amps), and UB-1500A (15- 1500 amps) are Linear DC controls with feedback modes designed to adapt to part and process variables. These power supplies should be used for smaller applications where closed-loop feedback control and fast response times are required. Safety critical applications such as those found in the medical and automotive markets will benefit from UB-500A’s precision low energy control.
