ENVIRONMENT
•
The welding environment should be dry, where humidity is below 90%
•
The environment temperature should range between 10˚C and 40˚C
•
Protect the machine against heavy rain, or in hot environments out of direct sunlight
•
Do not allow the machine to come into contact with water
•
Keep the environment free of dust, acid and corrosive gases
•
Ensure the environment is free from drafts
The SifWeld MTS200 welding machine has been installed with a pressure, flow and overheating protection
circuit. When the network voltage, output current and machine temperature exceeds a set standard, the
machine shall automatically stop working.
However, excessive use (such as high voltage) can still lead to damage of the welding machine, therefore
you shall need to pay attention to the following:
Ensure Good Ventilation
The SifWeldMTS 200 is a small sized welding machine which has an internal cooling fan to regulate
operating temperature during use. For optimum ventilation, the operator must ensure there is sufficient space
between the machine and surrounding objects, this must be a minimum of 30cm. It is vital to keep the
machine serviced and maintained on a regular basis.
Duty Cycle
The operator should always consider duty cycles for the current they are welding at, ensuring the duty cycle
is not exceeded. Should the duty cycle be exceeded, the Thermal Cut Out will engage therefore halting
welding operation. At the same time the overheating signal on the front panel shall activate and light up. In
this instance
do not unplug the machine, however allow the fan to cool the machine to the required
temperature to start welding again.
Current overload will reduce the service life, and could result in damage of the machine and even burning out
of the thermal inverter.
Mains Input Supply
Refer to the Recommended Weld Parameters within this manual for your chosen application.
Use the correct voltage input for your application, and ensure this is not exceeded. Voltage above the
maximum permitted voltage may cause damage to the welding machine.
Make sure the earth cable is connected correctly prior to using the machine to remove necessary
residual voltage.
2 Introduction
The SifWeld MTS200 is an inverter welder which adopts the latest Insulated Gate Bipolar Transistor (IGBT)
technology. The working principle is to use a single tube IGBT switching device rectifying input power into a
DC output then inverted to a high frequency, then stepped-down through the pulse width modulator (PWM)
to produce the welding output.
Using a digital liquid crystal (LCD) display panel, weld parameters can be adjusted via the MCP (Mono
Control Point) easily and accurately. The feedback circuit gives precise control of the welding arc, therefore
providing excellent welding characteristics.
The SifWeld MTS200 is an easily portable, multi-functional machine suitable for both on-site and workshop
use. Boasting stable wire feed speed, no electromagnetic noise, good arc force, molten pool and low spatter
along with high duty cycle. This unit is also energy efficient and is suitable for the welding of various
materials.
