Inverter Arc/MMA Welding Machine/Welder Arc250g
Welcome to our showroom! It's a great pleasure to introduce you to our high-quality welding machine, the ARC250G. This model is based on the Riland standard design, which was first introduced in 1987. Over the years, this Mosfet Inverter Technology has evolved into a highly stable and reliable system. Our experienced engineers, with over 15 years of expertise in this field, believe that the original Riland design is already very mature. Any modifications could potentially lead to performance issues, and we've seen many examples where other manufacturers faced problems after altering the design.
Please take a look at the internal photos of this model below:
All components are made from premium materials. We use top-quality parts such as new Toshiba K4107 or SL 18N50 transistors, HS transformers, D9202 diodes, Songle relays, and Sancon capacitors. These ensure both stability and durability.
