PAxxP Micro Arc Welding Supply

PaxxP datasheet

The  PAxxP range of programmable pulsed arc power supplies are linear based precision arc-welding units capable of producing repeatable and accurate current pulses. These units are specifically designed for high accuracy, solder free, zero contact joining often replacing solder and crimping techniques.  


Micro arc welding is a process that can be used to simultaneously remove wire insulation while forming a welded joint between the wire and target connection point in a matter of milliseconds.  This makes them an ideal choice for high speed manufacture of coil based products.  


Our PAxxP units use closed loop electronics to constantly monitor the arc and produce accuracies within 1%.

Arc Weld Monitor

Micro Arc Weld Monitor

A range of monitoring equpment designed for easy retrofit quality control monitoring and measurements for older welding equipment.  


These units utilise a SMART interface that provides 4 channels of independent input, 99 reference channels and a host of window tolerance features and SPC data capturing, allowing users to clearly measure, define and then control their process on older equipment.
