ARC 200 Welding Machine Repair | Output Problem Kaise Thik Karein?5 minutes में कैसे ठीक करे|

Doston, aaj ke is video mein maine ARC 200 MOSFET Welding Machine ke ek aise problem ko solve kiya hai jahan machine bilkul OK dikh rahi thi, saari lights aur fans chal rahe the, lekin output terminal par welding current nahi aa raha tha. Is video mein maine cover kiya hai: Machine ki basic testing (Input Power, Rectifier, and Capacitors). PWM Board ki checking aur signal testing. MOSFETs aur Driver Transformer ki condition check karna. The Final Solution: Maine bataya hai ki kaise maine wo "hidden fault" pakda jise aksar log miss kar dete hain. Agar aapki machine mein bhi OC (Over Current) light nahi jal rahi hai aur phir bhi output zero hai, toh ye video aapke liye hai! Repairing Steps & Checklist: Input Section: Sabse pehle 220V AC input aur bridge rectifier check kiya. DC Bus: Main capacitors par 300V-310V DC check kiya. Auxiliary Power: Control card ke liye 24V supply check ki. PWM Signal: PWM IC (SG3525/KA3525) se nikalne wala switching signal verify kiya. Driver Section: Driver transformer aur gate resistors ki value check ki. Final Output: MOSFETs ki switching aur output diodes (Fast Recovery Rectifiers) ko test kiya.
