OPERATION INSTRUCTION
1. Turn on the power switch, the screen will show set current value and ventilator is beginning to run.
2. Adjust knobs of welding current and arc-striking push, make welding function complies with
demands.
3. Generally, welding current is adequate to welding electrode according with as following:
Specification
φ
2.5
φ
3.2
φ
4.0
φ
5.0
Current
70-100A
110-140A
170-220A
230-280A
4. Knob of arc-striking drive is use to adjust welding function, especially in low current arrange, that is
cooperated with knob of welding current adjustment, they may adjust current of arc striking and be
out of control of knob of welding current adjustment. So, machine can gain powerful energy and
push current can achieve effect that may.
5. If the VRD equipment is installed in the machine. When the switch of back panel is put "ON"
position, the VRD indictor is lit, and when the switch is put "OFF" position, the VRD indicator is off,
then the no-load voltage is 67V. Switch of VRD is put inside the machine, with the "on" condition.
the no-load voltage changes to be less than 15V, which is safe for people.
6. The welding machine has been coordinated with remote control device:
1) Check the switch position of remote-control
device before operation .If the switch is on “OFF”
Position then is out of remote control. Switch is on “ON” position then is using remote control
device.
2) Insert plug of remote control in socket of remote control correctly and tighten firmly in order to
prevent poor contact.
3)
If remote control device is not used, make sure the switch is on “OFF” position, or welding
current will not be able to be adjusted on panel.
WARNING
！
Before connecting operation, please make sure all the power is turned off. The right
order is to connect the welding cable and ground cable to the machine first, and make sure they
are firmly connected and then put the power plug to the power source.
