1 Safety
Weldability Sif does not accept any liability for damage to the product or personal injury caused by ignoring
the safety instructions in this manual, or by negligence during installation, use, maintenance, and repair of
the product mentioned on the cover of this document and any corresponding accessories. Specific working
conditions or used accessories may require additional safety instructions. Immediately contact your supplier
if you detect a potential danger when using the product.
The user of the product is always fully responsible for observing the local safety instructions and regulations.
Observe all applicable safety instructions and regulations.
All work must be carried out by a trained personnel well-acquainted with the operation of the equipment.
Incorrect operation of the equipment may lead to hazardous situations which can result in injury to the
operator and damage to the equipment.
WARNING
Arc welding and cutting can cause injury to yourself and others. Take necessary precautions when
welding and cutting, ensuring you use adequate protection. Ask for your employer’s safety practices
which should be based on manufactures’ hazard data.
ELECTRIC SHOCK- Can Kill
•Install and earth the unit in accordance with application standards
•Do not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing
•Insulate yourself from earth and the workplace
•Ensure your working stance is safe
FUMES AND GASES - Can be dangerous to health
•Keep your head out of the fumes.
•Use ventilation, extraction at the arc, or both, to take fumes and gases away from your breathing
zone and the general area
ARC RAYS - Can injure eyes and burn skin
•Protect your eyes and body. Use the correct welding screen and filter lens, and wear protective
clothing
•Protect bystanders with suitable screens or curtains
FIRE HAZARD
•Sparks (spatter) can cause fite. Make sure therefore that there are no flammable materials nearby
NOISE- Excessive noise can damage hearing
•Protect your ears. Use ear defenders or other hearing protection
•Warn bystanders of the risk
MALFUNCTION- Call for expert assistance in the even of malfunction
•If you incur any difficulties curing the installation, please check the manual
•If you are unable to resolve your issue, please contact our Technical Department
Read and understand the instruction manual before installing or operating

TSX1D200MTS V1 FEB13- 5 -
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.

4 Installation
The SifWeld MTS200 is equipped with a network voltage compensation device, this ensures that when the
network voltage changes within the 15% range, the machine can still continue to work.
The cross-sectional area of any extension cable must be above the cross-sectional area of the machines
mains input cable to minimise voltage drop.
Prior to installation, check the following:
•Confirm both air-vents are no covered, obstructed or blocked otherwise this could result in failure of
the cooling system
•Ensure the machine is connected to a suitable grounded mains supply
Installation for MIG Applications
1. Connect to a suitable cylinder with required regulator and gas hose.
2. Select desired polarity via the quick-connect sockets on the front of the machine.
3. Select the MIG function via the switch inside the machine.
Fit the correct wire feed roll, and screw into place.

TSX1D200MTS V1 FEB13- 8 -
4. Install wire spool, by unscrewing the plastic retainer and placing the wire spool onto the spool hub.
5. Release the pressure arm.
6. Feed the wire into the guide tube, and through the wire feed roll. Set the correct pressure on the arm,
and fit back into place. Ensure that the pressure is enough to hold the wire in place, however not too
much as this will deform the wire.
7. Insert the MIG gun onto the front of the machine, and feed the wire through into the gun.
