The PPT-ARC-250 is a high-performance MMA welding machine designed for precision, reliability, and ease of use. It features a digital display meter and integrated Hot Start, Arc Force, and Anti-Stick functions, ensuring smooth arc ignition, stable welding performance, and reduced electrode sticking. The machine’s single PCB design makes it lightweight, compact, and portable, while allowing continuous welding at 25°C ambient temperature.Compatible with 6013, 7015, and 7018 electrodes, the PPT-ARC-250 offers a welding current range of 20–250 A and a voltage range of 20.8–30 V, supporting electrodes from 1.6 to 5.0 mm. Built according to EN60974-1 standards, it delivers a rated duty cycle of 25% at 40°C, a no-load voltage of 65 V, and an overall efficiency of 85%. With an IP21S protection class, insulation class H, and low operational noise (
