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
also.
Torch is damaged. 1. Using it without waiting cooling.
2. Changing the new one.
