3. USAGE INFORMATION
3.1 THE POWER SOURCE FRONT PANEL
● On the front control panel of the welding power source,there are Pilot lights, Welding current and voltage
controller,etc
(Figure 1)
● LED1: Pilot light of the power supply. The LED1 is lighted when SW1 switch is ON.
● LED2: Pilot light of Over-heating or Over current.The LED2 is lighted with thermal overload protection.

3.2 THE POWER SOURCE BACK PANEL
● SW1: ON/OFF Switch of the welding power source.
● Power source cable,
● Gas Input.
3.3 ADJUSTING THE GAS FLOW
●The indicators on the regulator at the tube side shows the pressure and the other shows the flow rate "L/min".
●Appropriate gas flow rate must be between 7 and 9 times of the diameter of the wire in use. The practical ratio is 8.
EXAMPLE:
Diameter of the wire: 0,8 mm.
Gas flow rate: 8 x 0,8 ≈ 6 L/min
3.4 ALIGNING DRIVE ROLLS FOR APPROPRIATEWIRE DIAMETER
Always control the rolls on the flange for compatibility with diameter of the
wire, because alignment problems are out of warranty.
●Both sides of the rolls are labeled according to appropriate wire diameter.
●Rolls must be inserted into the flange in such a way that appropriate diameter of the wire to be feeded is seen
from outside. After installing the rolls, the screws should be positioned and fastened.
3.5 ADJUSTING THE FREE WIRE LENGTH,WELDING CURRENT AND VOLTAGE
In order to obtain good welding characteristics, free wire length (L

instructions. The diameter of the wire (d) and the distance (L) between the nozzle and the contact tip is
important.
●Free wire length (L
) is the distance between the end of wire and the contact tip.
