4. 3 Description of inside

Please operate on the basis of following content

Step 1. Power on the back panel

Step 2. Inching the wire

The wire transmission equipment is internally installed from side fo this machine. Aligning wire

diameter and size of transmitting

roll

and fastening with dial.

Transiting the wire through plastic tube, impressing it from transmitting roll to connecter, then rocking the driving roll properly.

Welding torch is installed already. Pressing the torch switch and confirming until the wire

come out. (8 meter/minute)

Because the wire that come out from torch hurt face or hands, please not look into.

Step3. Setting starting run

4.4 Stable welding surroundings

·Around

a) The dry surroundings is best for welding, when humidity is above 90%, it is unsuited to welding.

b) Range of Necessary temperature is from-10 ̊C to 40˚C, beyond the range is unsuited to welding.

c) Direct sunlight for a long time or rainy day is unsuited to welding.

d) Welding is prohibited in where have Combustible or Strong corrosive

·Standard for safety

Protective circuit is designed on the welding machine for overvoltage, overcurrent ,overheating.

Input voltage, if input current and internal temperature exceeded rated value, the machine

automatically.

a) Please change of air as much as possible.

The melding machine run with high current, temperature of the machine is high, therefore , the smog or

heat can’t dissipate depending on airflow.cooling fan must be installed on the machine.

Please confirm that whether the ventilating fan is turning or not,is co vered or not .Be sure that machine

keep at least 30cm away from around .changing of air as much as possible contribute to lifetime of

machine.

b) Overload

Please confirm the maximum rated current and whether welding current exceeded the rated current or

not. Overload can shorten lifetime of machine and cause breakdown.

stop run

c) Overvoltage

Input voltage can be knowed by technical data. Welding current is controlled in the rated range by special supplement functions. If input voltage exceeded allowable limits, the machine may be damaged. please take steps to avoid malfunction in advance.

d) Please not power off when keeping defensive function

If run for a long time and exceed rate of utilization, the machine stay defensive status , the machine stop

operation as temperature sensor is started. If the machine is off and power on again before cooling fan

power on at the moment, it may cause malfunction and destroy.

4.5 The problem of welding and solution

About the problem that accessory

or welding material,power supply caused,is described as followings.

Generation of arc is difficult, and disconnect in halfway

a) Is earth wire and welding part is installed hardly?

b) Confirming that whether joint part and contact part loosen or not?

Output current

didn’t reach rated

value

.

The deviation of rated value and supply voltage may cause inconformity of output current and adjusted

value. If supply voltage below specified value, maximum output current can below specified value also.

Current is unstable when machine is running.

In

most

cases, above problem relate to

following reasons.

a) The changes of voltage

b) Distraction of other Electric machine

5 Daily Maintenance Or Check Points

Daily Maintenance

a) Be sure to clean Compressor internal dust or waste at regular intervals. Welding machine work in

harsh environments that always generate smog, therefore please clean the dust at least once a

month.

b) Please examine inside of machine, and check that whether fixed torch or earth wire occur loosening

and scar. Please wipe out with sandpaper if rust.

c) Be careful using in high humidity or heavy weather to avoid water permeating into the machine. In

case of machine moistened , dry in the air and then bring in for a repair.

d) When don’t use machine for a long time, enclose it into original box and seal fully, store it in dry environment

WARNING

When machine power is off fully, all of maintenance project will be cleared. Please confirm that

machine power is off.

Remarks

Checking the size of chips If it is off size, the arc become unstable.

The size of Each parts

don’t fit the wire diameter.

Please confirm when arc become unstable.

Transmission Equipment Didn’t welding wire coil

expand? Please change wire.

Cleaning

transmission equipment or passageway of wire

Once transmission equipment or

passageway is blocked, wire can’t move

past smoothly, therefore it can’t welding
