2. OVERVIEW
• 2.1. Brief Introduction
RONCHWELD 250MIG
arc welding machine adopts the latest pulse width modulation (PWM)
technology and insulated gate bipolar transistor (IGBT) power module, which can change work
frequency to medium frequency so as to replace the traditional hulking work frequency
transformer with the cabinet medium frequency transformer. Thus, it is characterized with
portable, small size, light weight, low consumption and etc.
RONCHWELD 250MIG arc welding machine uses Mix gas as shielded gas to realize gas shielded
welding, active gas

RONCHWELD 250MIG arc welding machine has automatic protection functions with intelligent to
over-voltage, over-current and over-heat. If any one of the above problems happens, the alarm
lamp on the front panel will be lighted and output current will be shut off automatically to protect
itself and prolong the equipment using life.
RONCHWELD 250MIG Features:
Digital control system, real-time display the welding parameters;
High performance multifunction power source (MIG/MAG);
Waveform control, stable welding arc;
IGBT technology, low power dissipation;
Rated duty circle
