MACHINE DESCRIPTION

The we ding machine is a rectifier adopting the most advanced inverter techno ogy.

The deve opment of inverter gas-shie ded we ding equipment profits from the deve opment of the

inverter power supp y theory and components. Inverter gas-shie ded we ding power source uti izes

high-power component MOSFET to transfer 50/60Hz frequency up to 100KHz, then reduce the vo tage

and commutate, and output high-power vo tage via PWM techno ogy. Because of the great reduce of

the main transformer’s weight and vo ume; the efficiency increases by 30%. The appearance of inverter

we ding equipment is considered to be a revo ution for we ding industry.

CO2 shie ded we ding equipment adopts the most advanced inverter techno ogy by our. Inside of the

machine is equipped with e ectronic reactor circuit which can accurate y contro the process of the

e ectric short transition and b ending transition and resu t exce ent we ding characteristic. Comparing

with synergic we ding machine and other machine, it has the fo owing advantages: stab e wire speed,

compact, power saving, no e ectromagnetic noise. Continuous and stab e operation with sma current,

especia y suitab e for we ding sheet of ow-carbon stee , a oyed stee and stain ess stee . Automatic

vo tage pu sation compensation capabi ity, sma spark e, good arcing, uniform we ding poo , high duty

cyc e and so on.

The welding machine to meet the temperat re rise of 40 degrees ambient temperat re and rated

load cycle req irements.

The welding machine belongs to the CISPR11 first gro p eq ipment.

Thanks for purchasing product and hope for your precious advice. We wi dedicate to produce the best

products and offer the best service.

INSTALLATION INSTRUCTION

The we ding equipment is equipped with power vo tage compensation set. When power vo tage

f uctuates between±15% of rated vo tage, it sti works norma y.

When using ong cab e, in order to minimize the reduce of vo tage, big section cab e is suggested. If the

cab e is too ong, it wi affect the performance of arcing and other system function, so stated ength is

suggested.

1. Make sure the intake of the machine is not covered or b ocked to prevent the ma function of the

coo ing system.

2. Use earth cab e that the section no ess than 6mm2 to connect the housing and earth, the method is

from the connection in the back of the machine to the earth set, or make sure the earth end of

power switch reaches the earth. Both ways can be used for better security.

MIG 200Installation：

1) Connect the gas f ask with CO2 decompression f ow meter and the CO2 mouth behind the machine

via gas cab e.

2) Insert the swift p ug of earth cab e into the swift socket in the front pane .

3) Set the wire whee with wire on the whee axis, the

whee ho e shou d be matched with the whee fixer.

4) Choose wire s ot according to wire size.

5) Loosen the screw of wire-pressing whee , pit the wire

into so t via wire- ead tube, tune the wire-pressing

whee to fix wire from g iding, but pressure shou d be

suitab e in case the wire distorts and affects wire

sending.

6) Wire ro shou d turn c ockwise rotation to et out wire,

to prevent wire from g iding, wire is usua y set to the

fixed ho e on the whee side. To prevent the bent wire

from getting stuck, p ease cut off this part of the wire.

7) Put and tighten the torch on the output socket and put

the wire into the torch by hand.

OPERATION INSTRUCTION

1. Put the air switch to “ON” position, open the va ve of argon cy inder and adjust the f ow.

2. Adjust the wire diameter of the wire machine to rated number according to wire diameter.

3. Choose torch oopho e span based on wire diameter.

4. Tune the vo tage and speed knob to the right position based on the thickness of the work piece and

mechanics.

5. Press the torch switch to et out the wire to the torch head and begin to work.

NOTES OR PREVENTIVE MEASURES

1. Environment

1） The machine shou d be operated in dry environments with humidity eve s of max 90%.

2） Ambient temperature shou d be between -10 to 40 degrees centigrade.

3） Avoid we ding in sunshine or drippings. Do not et water infiter the machine.

4） Avoid we ding in dust area or the environment with corrosive gas.

5） Avoid gas we ding in the environment with strong airf ow.

2. Safet norms

The we ding machine is insta ed with protection circuit of over vo tage, over current and over heat.

When vo tage, output current and temperature of machine exceed the required standard, we ding

machine wi stop working automatica y. However, overuse (such as over vo tage) wi sti resu t in

damage to the we ding machine. To avoid this, the user must pay attention to the fo owing.

1） The working area is adequatel ventilated！

The we ding machine is powerfu machine, when it is being operated, it generated by high

currents, and natura wind wi not satisfy machine coo demands. So there is a fan in

inner-machine to coo down machine. Make sure the intake is not in b ock or covered, it is 0.3

meter from we ding machine to objects of environment. User shou d make sure the working

area is adequate y venti ated. It is important for the performance and the ongevity of the

machine.

2） Do not over load！

The operator shou d remember to watch the max duty current (Response to the se ected duty

cyc e). Keep we ding current is not exceed max duty cyc e current. Over- oad current wi

damage and burn up machine.

3） No over voltage！

Power vo tage can be found in diagram of main technica data. Automatic compensation

circuit of vo tage wi assure that we ding current keeps in a owab e range. If power vo tage is

exceeding a owab e range imited, it wi damage to components of machine. The operator

shou d understand this situation and take preventive measures.

4） There is a grounding screw behind we ding machine, with a grounding marker on it. Before

operation , we ding crust must be grounded re iab e with cab e which section is over 6 square

mi imeter, in order to prevent from static e ectricity , and accidents because of e ectricity

eaking.

5） If we ding time is exceeded duty cyc e imited, we ding machine wi stop working for protection.

Because machine is overheated, temperature contro switch is on “ON’’ position and the

indicator ight is red. In this situation, you don’t have to pu the p ug, in order to et the fan coo

the machine. When the indicator ight is off, and the temperature goes down to the standard

range, it can we d again.

·OWNER’S MANUAL· - 7 - SMC-003-A3

QUESTIONS TO BE RUN INTO DURING WELDING

Fittings, we ding materia s, environment factor, supp y powers maybe have something to do with

we ding. User must try to improve we ding environment.

A. Arcing-striking is difficult and eas to pause：

1) Make sure the earth cab e c incher connects the work piece we .

2) Check each connecting point connected or not.

B. Output current can not reach rated volume：

That supp ied vo tage is different from the rated wi ead to unconformity of the output current and the

adjusted current. When Supp ied vo tage ower than the rated, the max output current wi be ower than

the rated.

C. Current is not stabilizing when machine is been operating.

It has something with factors as fo owing.

1) E ectric wire net vo tage has been changed.

2) There is harmfu interference from e ectric wire net or other equipment.

D. Welding gap has air hole.

1) Check the gas supp y oop eaks or not..

2) Surface of mother materia has oi , stain, rust, acquer or other impurity.

MAINTENANCE

WARNING：

Before Maintenance and checking, power must be turned off, and before opening the

housing, make sure the power plug is pulled off..

1. Remove dust by dry and c ean compressed air regu ar y, if we ding machine is operating in

environment where is po uted with smokes and po ution air, the machine need remove dust every

month.

2. Pressure of compressed air must be within the reasonab e range in order to prevent damaging to

sma components of inner-machine.

3. Check interna circuit of we ding machine regu ar y and make sure the circuit connections are

connected correct y and tight y (especia y p ug-in connector and components). If sca e and rust are

found, p ease c ean it, and connect again tight y.

4. Prevent water and steam from entering into the machine. If that happens, p ease b ow it dry and

check insu ation of machine.

5. If we ding machine wi not be used for ong time, it must be put into the packing box and stored in

dry and c ean environment.

6. When wire machine operates for every 300 hours, the e ectric carbon brush and armature recitifier

shou d be added to the turbo and bearing.
