Welder’s Principle
(see following picture)
The 410-PROTIG20 welder applies advanced IGBT(insulated gate bipolar transistor)and rapid
recovery diode as it’s the main power piece of the power transformation and transfer, with which the
arc can be minutely controlled. It is also assisted with gas pre-flow
、
gas post-flow and non-contact
high frequency pilot, all which contribute to the machine with the feature of high reliability and fast
dynamic response speed and stable arc.
Welding machine by air switch SW - SPST single-phase 220 v alternating current (ac) power frequency, the BD1
single-phase rectifier bridge rectifier and capacitor C1 C2 C3 filtering into direct current (dc), via the IGBT (Q1, Q2
Q3 Q4) consisting of a full bridge inverter ac inverter into to 36 KHZ, then through intermediate frequency
transformer T1 transformer, the quick restore tube D1, D2 D3 D4 D5 D6 D7 D8 rectifier, output steady dc power
