OPERATION

Argon-arc Welding

1. Make sure the power switch is in "on" position and the indicator will be lit.
2. Open the valve of argon cylinder and adjust the volume of flow meter.
3. Inter axial-flow fan will now begin to work. Press the control knob of the torch so that the elec-
tromagnetic valve will start. The user can hear a sound of HF arc-striking, at the same time
the argon will start flowing out of the torch tip.
4. The knob of arc-striking push is used to adjust the welding function, especially in a low cur-
rent range, that is cooperated with knob of welding current adjustment. They may adjust cur-
rent 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 imitate DC welder re-
volving.
5. The distance from welding tungsten electrode to work piece needs to be 2-4 mm. Then you
need to press the control knob. Burning and striking the arc the sound of HF arc-striking will
be diminished. The welding machine can be operated now.
Striking Description

1. Open the power switch of front control panel so that the fan starts working.
2. Make sure the function switch is on "down" position.
3. Set the welding current adequate to thickness of work piece.
4. Adjust welding characteristic by drive knob.
NOTE: Do not touch any cable and connector when the machine is working, it can cause damage to
health of people or the machine itself.

MAINTENANCE

1. Remove dust by dry and clean compressed air regularly. If welding machine is operating in envi-
ronment with polluted air or smoke, the machine needs to be cleaned of dust every day.
2. Pressure of compressed air must be inside the reasonable arrangement in order to prevent dam-
aging to small components of inner machine parts.
3. Check inter circuit of welding machine regularly and make sure the cable circuit is connected cor-
rectly and connectors are connected tightly (specially insert connector and components). If scale
and loose are found, please give a good polish to them and then connect them tightly again.
4. Avoid water and steam to enter into the machine. If they enter the machine, please dry
chine and then check insulation of machine again (including between connectors and mantle, be-
tween connectors and connectors).
5. If welding machine will not be operated for longer times, it must be put into packing box and
stored in dry environment.
