SAFETY PRECAUTIONS
WELDING AND ARC CUTTING CAN BE HARMFUL TO YOURSELF AND OTHERS
The user must therefore be educated against the hazards, summarized below, deriving from welding/cutting operations.
ELECTRIC SHOCK - May be fatal.
- Install and earth the welding/cutting machine according to the applicable regulations.
- Do not touch live electrical parts or electrodes with bare skin, gloves or wet clothing.
- Isolate yourselves from both the earth and the workpiece.
- Make sure your working position is safe.
- Prior to performing maintenance make sure the unit is disconnected from the power source.
FUMES AND GASES - May be hazardous to your health.
- Keep your head away from fumes.
- Work in the presence of adequate ventilation, and use ventilators around the arc to prevent
gases from forming in the work area.
- Do not breathe in the fumes. Use proper ventilators and masks.
ARC RAYS - May injure the eyes and burn the skin.
- Protect your eyes with welding masks fitted with filtered lenses, and protect your body with
appropriate safety garments.
- Protect others by installing adequate shields or curtains.
RISK OF FIRE AND BURNS
Sparks (sprays) may cause fires and burn the skin; you should therefore make sure there are no
flammable materials in the area, and wear appropriate protective garments.
NOISE
This machine does not directly produce noise exceeding 80dB. The plasma cutting/welding procedure
may produce noise levels beyond said limit; users must therefore implement all precautions required by
law.
PACEMAKERS
The magnetic fields created by high currents may affect the operation of pacemakers. Wearers of vital
electronic equipment (pacemakers) should consult their physician before beginning any arc welding,
cutting, gouging or spot welding operations.
EXPLOSIONS
Do not weld/cut in the vicinity of containers under pressure, or in the presence of explosive dust, gases or
fumes. · All cylinders and pressure regulators used in welding operations should be handled with care.

MISUSE
LIMITED WARRANTY VOID
IMPORTANT
Your CT series unit is equipped with three different functions. Please take note of the
following operational guidelines. Failure to adhere to the following operations guidelines
will causes severe damage to you machine and will render the Limited Warranty void.
The following is not meant to be an all inclusive list of situations where the Limited
Warranty is rendered void. It is meant to serve as an example. Please review the
remainder of this manual and the terms of Limited Warranty supplied herein for further
details.
OPERATE ONLY ONE FUNCTION AT A TIME
Using multiple functions simultaneously will lead to severe damage to the unit and render the warranty void.
DO NOT SWITCH BETWEEN FUNCTIONS DURING OPERATION
While engaged in operating one of the functions, do not switch to another function. For example, if you are engaged in
plasma cutting, do not change the toggle switch of the Function Selector to TIG or MMA.
CONFIRM CORRECT SETTING BEFORE OPERATION
Confirm that the function selector is set to the proper setting before beginning operation. For example, do not attempt
to use the plasma torch function while the machine’s Function Selector is on TIG. This will lead to serious damage to
the unit
DO NOT USE PLASMA TORCH IN MMA OR TIG MODE
Using the plasma torch while the machine is switched to the MMA or TIG function will result in damage to the plasma
torch and the CT machine.
INCORRECT WIRING
Failure to connect the CT unit correctly to the main input power source will result in severe damage to the unit and may
lead to the risk of injury, death or electrocution. Please follow the wiring diagram supplied with your machine

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.

NOTES ON DX SERIES
DX Series – Equipped with Digital Amperage Display
. The digital display panel may remain lit for a period of up to minute after turning off the unit. This
is normal.
2. The digital display of Amperage may display a value that exceeds or fall short of the
maximum/minimum performance parameters of the unit. This is normal within a 5- 0% range.
3. The digital display of Amperage may fluctuate during operation. This is normal.
4. The AMP level on the digital display may not correspond with the printed AMP level on the panel.
This is normal. In case of discrepancy, rely on the digital display.
5. Fluctuations of digital display during operation are considered normal.
