OPERATION INSTRUCTION
1. Open the power switch, screen will show set current volume and ventilator is beginning to revolve.
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.

4. Knob of arc-striking drive is use to adjust welding function, specially 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 grain powerful energy and
push current can achieve effect that may .
5. If the anti-shock device 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 60-70V. 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. If welding machine has been coordinated remote control device:
1)
Make sure the switch position of remote control device before operation .If switch is on “OFF”
Position that is out of remote co
ntrol. Switch is on “ON” position that 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 be used, make sure the switch is
on “OFF” position, or welding
current will not be adjusted on panel.
7. Hot initiation: Heavy current, perfect effect, striking easier.
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.
