follows:adjust the required welding parameter,press channels selection knob,the voltage LED display the present
channel,if need to storage,press storage knob.If need to storage the parameter to other channels,continue to press
selection channel till find the required channel,then press storage knob.It will return to the present adjustment
parameter if without any operation within 5s.
f
、
Parameter selection: press the knob to select any parameter of any channels,as follows:press channel selection
knob,to select the suitable parameter,and press selection parameter knob.
g
、
Current selection:Press it to choose the welding current,arc force or hot start.
h
、
Control mode: press and choose the mode.
i
、
Overload: it on,mean overload,need to stop working and temperature drop.
j
、
Input fault: the indicator on means the power miss-phase or undervoltage,meanwhile,power off and check the
power supply.
k
、
welding current:the indicator on means current LED display the present welding current.
l
、
Arc force: the indicator on means the current LED display the arc force current.It will return to welding current
indicator without any operation within 3s.
m
、
Hot start: The indicator on means the current LED display the hot start current.t will return to welding current
indicator without any operation within 3s.
n
、
Locate: the indicator on means available to adjust the parameter on the power source.
o
、
Remote: the indicator on means not able to adjust any parameter on the power source,only adjust welding
parameter by remote control box.
p
、
Channel No.: the indicator on means voltage LED display the present channel no.
q
、
Voltage(V): the indicator on means voltage LED display the present voltage.
r
、
Current(A): “on”mean the LED of current display the actual current.
s
、
Preset indicator: “on “mean the LED of current display the preset current.
Note:
1
、
The machine have intelligent fan function,it will work after power on but without welding for 15s,then stop;Fan
keep rotating during welding,and stop after 8mins if end welding.
2
、
The machine have anti-electric shock function,welding machine will output the safety voltage 8-10V if machine
power on but without welding.When welding,output the normal arc voltage,but it will drop to the safety voltage if
no welding after 1s.

Maintenance
Install and operate the machine strictly according to the operator's manual, the warranty period is one year.
Troubleshooting
TROUBLE (SYMPTOMS)
POSSIBLE CAUSE
RECOMMENDED COURSE OF ACTION
When machine energized, the
circuit breaker trip
1.Three phase bridge rectifier may
damaged
2. The capacitor which parallel with the
three
phase
bridge
rectifier
may
damaged.
3. IGBT may damaged
1.
change the bridge rectifier
；
2. change the capacitor.
3. Replace PCB and IGBT
2.
When machine energized, the
power indicator not on, no voltage
indication
1.
The protective fuse on the back of the
machine may break
2.
Lack phase
1.
Replace fuse
2.
Check the input power
When machine energized, the
power indicator on, but no voltage
indication
1.
PCB AP1 may damage
2.
IGBT module may damage
3.
Voltmeter may damage
1.
Replace AP1
2.
Replace IGBT module
3.
Replace voltmeter
