WARNING!
Electric Shock can kill Only qualified personnel should perform this installation. Turn off input power at the
fuse box before working on this equipment. Do not touch electrically live parts. Always connect the machine
to an earthed mains supply as per national recommended standards.
Select suitable location
Place the welder where clean cooling air can freely circulate in and out of the front & rear louver vents. Dirt,
dust or any foreign material that can be drawn through vents into welder must be kept to a minimum. Failure
to observe these precautions can result in excessive operating temperatures which can lead to plant failure.
Grinding
Do not direct grinding particles towards the welder. An abundance of conductive material can cause plant
failure.
Stacking
This machine cannot be stacked.

Transport Unloading
Never underestimate the weight of equipment, never move or leave suspended in the air above people. Use
recommended lifting equipment at all times.
WARNING!
Falling Equipment can cause injury. Never lift welder with gas bottle attached. Never lift above
personnel.
Tilting
Machine must be placed on a secure level surface or on a recommended undercarriage/trolley. This
machine may topple over if this procedure is not followed.
Environmental Rating
The welding power source carries the IP21S rating. It may be used in normal industrial and
commercial environments. Avoid using in areas where water / rain is around.
Read and follow the Electric Shock Warnings in the safety section if welding must be performed under
electrically hazardous conditions such as welding in wet areas or water on the work piece.
Machine grounding and High Frequency Interference Protection
This welder must be grounded to earth. See national electrical codes fro proper grounding
methods.
The high frequency generator being similar to a radio transmitter may cause interference to radio, TV and
other electronic equipment. These problems may be the result of radiated interference. Proper grounding
methods can reduce or eliminate this.
Radiated interference can develop in the following ways
1 Direct interference from welder power source
2 Direct interference from the welding leads
3 Direct interference radiated from feedback into power lines
4 Interference from re-radiation by un-grounded metallic objects.
Keeping these contributing factors in mind, installing equipment as per following instructions should minimize
problems.
1 Keep the welder input power lines as short as possible and enclose as much of them as possible in
metal conduit or equivalent shielding. There should be a good electrical contact between this conduit and
ground (Earth).
2 Keep the work and electrode leads as short as possible. Tape the leads together where practical.
3 Be sure the torch and earth leads rubber coverings are free from cuts and cracks that allow welding
power leakage
4 Keep earth lead connection to work in good condition Clean area on workbench where earth clamp
is situated on a regular basis.

Input Connections
Make sure the voltage, phase and frequency of input power is as specified on machine rating plate located
at rear of machine.
Have a qualified electrician provide suitable input power as per national electrical codes. Make sure machine
is earthed / grounded.
Make sure fuse or circuit breaker is correct rating for machine. Using fuses or circuit breakers smaller
than recommended will result in nuisance shut off from welder inrush currents even if welding at low
amperages.
On multiple voltage input welders, be sure the machine is connected as per the instructions for the voltage
being supplied to welder Failure to follow these instructions can cause immediate failure within the welder
and void machines warranty.
WARNING!
ELECTRIC SHOCK CAN KILL
Turn the input power OFF at the mains switch & fuse box before working on this equipment.
Have a qualified electrician install & service this equipment.
Allow machine to sit for 5 minutes minimum to allow the power capacitors to discharge before
working inside this equipment. Do not touch electrically live parts
The POWER MTS175S Inverter Welder requires a 230V 50/60Hz 29amp power supply.
It comes with a 3 metre mains cable attached.
Connect wires according to national coding.
Brown wire - Live
Blue wire - Neutral
Green/Yellow Wire - Earth (Ground)
Connecting to a mains electrical supply
THIS MACHINE IS OF AN INDUSTRIAL SPECIFICATION AND CAN CONNECT
WITH 16A SOCKET.
Connecting to an Engine Driven Generator
I
f connecting this machine to an engine driven generator please ensure
the following Minimum Generator KVA Output - 7.5 KVA
continuous Generator to be fitted with AVR (automatic voltage regulation)
DO NOT USE ON A GENERATOR WITHOUT AVR Connecting to a generator
without the above minimum requirements will invalidate your warranty.

Product Description
The MTS175S is a member of our field acclaimed family of welding products.
This kind of welding power Model MTS175S is taken foreign advanced technology to develop and
manufacture the new generation inverter integrated controlling Semi-auto MIG/MAGMMA Arc welding
machine.It makes use of the import key parts such as Siemens IGBT module of Germany,alloy magnetic
core and the resume diode module of America. It has the perfect performance of high quality ,good
reliability, quick speed of welding current, steady welding process,low splash and good welding form .
Anyway,It becomes the welding very easy.
Recommended Processes
The
POWER MTS175S
is recommended for the MIG welding processes within its output capacity of
170 Amps DC
Equipment Limitations
The POWER MTS175S is protected from overloads beyond the output ratings and duty cycle as per
machine specifications with thermostat protection of the output coils and rectifiers.
Welding Capability Duty Cycle
The POWER MTS175S is rated at 170 Amps(MIG) at 35% duty cycle on a ten minute basis. If the
duty cycle is exceeded a thermal protector will shut machine off until the machine cools.
The POWER MTS175S is rated at 150 Amps(MMA) at 35% duty cycle on a ten minute basis. If the duty
cycle is exceeded a thermal protector will shut machine off until the machine cools.
The POWER MTS175S is rated at 170 Amps(TIG) at 35% duty cycle on a ten minute basis. If the duty
cycle is exceeded a thermal protector will shut machine off until the machine cools.

a、The meter on the front panel can indicate the actual welding voltage or preset MIG voltage.The
indicating number has the precision of 0.1V .The meter indicates the preset during no welding.
b、display MMA arcforce
c、display tig downslope time
2. Current indicating
The current indicating meter on the front panel indicates the actual welding current during the
welding，indicates the preset current during no welding.
3. Power indicating
If the indicating light is on the control circuit connects the power already.

5. indicator wire speed right display
6. indicator current right display
7. MIG/TIG/STICK Process Selector
Each icon graphically repre-sents each process for rapid eye acquisition when changing processes.
The top function represents MIG. The middle function repre-sents TIG. The bottom function represents
Stick.
8. indicator voltage left display
9. Amp/Wire Speed Adjustment Knob
For Stick and TIG function, this adjusts the amps. For MIG opera-tion,the amps are directly tied to the
wire speed feed. Increasing the speed increases the amps and vice versa. While the unit displays in
m/min for MIG operation, a change in this control also results in a change of amps.
10. Duty Cycle/Overcurrent Warning.
When the duty cycle has been exceeded or an overcurrent, condition has occurred, the L.E.D. will light.
Allow the unit to cool while running until the light goes off or for 10 minutes before resetting the welder. If
condition persists check for loose wires or voltage supply problems.
11. MIG Wave Form Control.
Varies the slope of the current rise time between during short circuit MIG operation. This affects the
actual point where the current has risen sufficiently to burn back the wire.
