INTRODUCTION TO RAMSOND CT Series
Ramsond CT series is a multi-functional welder/plasma cutter made
with advanced inverter technology. The CT series has three
functions: TIG/MMA/CUT. They are dual voltage (110 and 220 V)
and can operate with both 50 and 60 Hz frequencies. The inverter
power is the power that first changes 50/60 Hz working frequency to
high frequency (as high as 100 Hz) with high power factor V-MOS,
and then reduces the voltage and rectifies through PWM (Pulse
Width Modulation), creating high factor welding and cutting power. By
using the inverter technology, the weight and volume of the mains
transformer has been greatly reduced as compared with conventional
machines, while the efficiency has been raised by over 30％. When
working as MMA or TIG, the outer characteristic of the RAMSOND
CT series is constant current and the welding current doesn’t change
with the length of the arc. In this case current is very stable. When
working in plasma cut mode, the arc is compressed by the rapid-
circulating air, and then its temperature reaches 10000 ～ 15000
degrees in the state of ionization, thus turning into strong plasma arc.
Ramsond CT series units can be widely used in welding and cutting
carbon steel, stainless steel, alloy steel, copper and other nonferrous
metals. They are portable, efficient, energy-saving and stable.
