Micro-welding \u00b7 Short-circuit protection<\/div>\n

MCB Magnetic Trip Set Automatic Welding Machine<\/h1>\n

The MCB magnetic trip set automatic welding system is a quick, automated welding machine that functions to weld solenoid coil lead wires to the internal current path (also known as the bus) of miniature circuit breakers\u2019 magnetic trip units. By employing a modern micro-resistance or laser welding process, the machine creates ultra-low resistance and high-integrity connections that are critical for ensuring dependable short circuit protection. The machine is equipped with features for wire stripping, accurate component location, and programmable weld parameters to assure that all joints will meet the organisation’s joint quality specifications throughout high volume production.<\/p>\n

Pre-assembled magnetic yokes and solenoid coils are accepted by the system; wire ends are stripped and aligned with the terminal pads automatically; a controlled weld pulse is applied after alignment. Resistance is verified after the weld (typically…<\/p>\n

What is an MCB Magnetic Trip Set Automatic Welding Machine?<\/h2>\n

Automatic welding machines equipped with magnetic trip units (MCBs) are a type of special production unit designed to automate the electrical connection between the solenoid coil leads and the current-carrying path through the trip unit of a miniature circuit breaker (MCB). When a circuit breaker is tripped due to a fault condition, the trip unit provides instantaneous short-circuit protection; any resistance at the point of welding will cause a delay in the trip time or generate excess heat at that location. To provide a reliable, low-resistance, mechanically strong weld without damaging the fine copper wires used to create the solenoid coil leads, these automatic welding machines utilize either micro-resistance welding or laser welding as the welding technique. Typically, the automatic welding machines include an automatic wire stripping station, a vision system for alignment, a welding head with force control, and a post-weld resistance verification device \u2013 all of which are sequenced and controlled by a PLC (programmable logic controller).<\/p>\n

Ultra-low contact resistance<\/h4>\n

Manual soldering often results in joint resistance of 0.5-2 m\u03a9, causing unwanted voltage drop and slower magnetic trip response. This machine consistently achieves <0.1 m\u03a9<\/strong>, ensuring instantaneous trip timing within IEC 60898-1 limits.<\/p>\n<\/div>\n

\n

No thermal damage to coil<\/h4>\n

Micro-resistance welding delivers a concentrated energy pulse in milliseconds, preventing heat from traveling up the fine coil wires \u2013 unlike soldering which can melt insulation.<\/p>\n<\/div>\n

\n

Integrated quality verification<\/h4>\n

An inline resistance tester measures each joint immediately after welding. Assemblies failing the <0.1 m\u03a9 threshold are automatically rejected, preventing defective magnetic trips from reaching final assembly.<\/p>\n<\/div>\n

\n

Laser welding option for delicate designs<\/h4>\n

For very fine wires (<0.3mm) or hard-to-reach joints, a fiber laser welding module provides non-contact, high-precision joining with minimal heat-affected zone.<\/p>\n<\/div>\n<\/div>\n

After they implemented a magnetically actuated automatic welding machine for their motors’ trip mechanism, the customer experienced a reduction in weld resistance variability of welds from a range of \u00b11.5 milliohms to a range of \u00b10.03 milliohms. They had an initial 2.5% field failure rate due to excessive contact resistance in the trip mechanism’s contacts caused by inconsistent hand soldering. The customer experienced a 0.1% field failure rate after the magnetic trip mechanism was welded. The customer previously produced 800 welded units per shift before using our machine, and after welding, they were producing 1,800 welded units per shift. The machine paid for itself within seven months of being implemented by the customer.<\/p>\n
