Installation Instructions

2.1 Welding Wire Installation Steps:
To install a fresh reel of welding wire into the wire feeder. The hole position of the wire plate should be aligned with the fixed plug on the shaft. The wire reel should be rotated so that the wire feeds from the bottom of the reel into the wire feeder. Following the diagrams below as a guide, place the reel over the spindle in the machine and fasten it into place with the washers, spring and nut. There should be slight tension on the reel, just enough to prevent it from unwinding. While using one hand to prevent in the wire from suddenly unwinding from the reel, loosen the free end of the wire from the edge of the reel. Snip off the crooked or bent tip and insert the tip of the wire into the metal spring wire guide of the wire feeder.

According to the type and diameter of the wire, select the appropriate wire feed roller. V-grove roller for stainless steel and carbon steel, Knurled- grove roller for flux cored wire and U-grooved roller for welding aluminum in the spool gun (spool gun and U-groove roller are not included with the machine and must be purchased separately.) Please match diameter size on the roller with the welding wire diameter. Please note that the wire feeder feeds the wire over the inboard side of the feeder mechanism make sure you install the drive roller so that the desired groove is towards the machine!
Release the drive tension mechanism by rotating the drive tension knob down. Now pass the wire through the wire guide spring over the top of the groove of the drive wheel. Using your finger to aim the wire thought the second guide that is at the front of the machine. Push the wire out a few inches or centimeters. Now bring down the top roller mechanism and raise the tension knob to lock it into place. Adjust the tension knob so that the pressure on the welding wire, guarantees the welding wire is not slipping if the wire is blocked, and not continuing to fed the wire, This would cause a huge mess called a bird’s nest inside the machine.

How to welding aluminum:
Because aluminum dissipates heat very quickly, more heat is required during welding, and the cooling speed of the workpiece is too fast, resulting in that the gas generated by various reasons cannot be discharged in time during the welding process, resulting in the formation of pores. The melting point of aluminum is only 600 ℃, and the welding current is slightly high, causing the workpiece to burn through. Aluminum is also very easy to oxidize. The melting point of the surface Aluminum oxide is 2000 ℃, which is very different from that of aluminum. The Aluminum oxide will form welding protection for aluminum; Aluminum has good ductility and soft material, which makes wire feeding difficult; The expansion coefficient of the welding line is large, and it is easy to deform and produce cracks, which brings great difficulties to the welding of aluminum.
Precautions for aluminum welding:
Clean the oxide film on the aluminum surface with a stainless steel brush, and clean the aluminum welding wire surface with acetone.
Select MIG mode for machine function and switch the gun mode to spool gun mode.
Correctly connect the spool gun to the machine(DCEP).
Install the aluminum welding wire with matching diameter to the spool gun.
Welding aluminum must be protected with 100% argon.
Push welding is adopted, which is called left welding, that is, push welding from the right to the left.
Select the appropriate current according to the thickness of aluminum material. You can try to start with a small current until you find the appropriate current.
The position and angle of the gun head shall be adjusted according to the position of the welding space, and the speed of the technique shall be determined according to experience. However, when the molten pool is initially formed, the welding gun shall be pushed forward.
How to weld wires of other diameters
Based on the powerful intelligent capability of the digital control panel, the machine has automatically set the current and voltage parameters of welding wires with different diameters in different modes, which is very friendly to novice users.However, due to the space limitation of the operation panel, the machine cannot display all the welding wire specifications with different diameters on the panel for the user to choose, and can only select the most commonly used welding wire specifications for the user to choose. How to weld the welding wire that is not on the operation panel? This is an interesting thing.
Precautions for welding wires with other diameters
Prepare a wire feeding wheel that matches the diameter of the welding wire. The knurled wheel or U-shaped wheel is used for flux cored welding wire, and the V-shaped wheel is used for solid cored welding wire.
Prepare for welding according to MIG mode.
Machine function selection MIG mode.
Select the option close to the actual welding wire diameter on the control panel.
Optimize voltage matching parameters through Voltage minor adjust knob.
Start welding.
Adjust the current and fine adjust the voltage according to the actual welding conditions.
Fault display:
OC light
When the welding load is overloaded and the output current of the machine is too large, the internal temperature of the machine will become too high, and the machine fault light will come on. This is normal. The machine will recover after it cools down and the temperature has returned to normal. If it does not, please shut the machine down and restart it. If the machine is damaged, the fault light will be on, in this case, the machine needs maintenance, please contact the supplier.
3.3 Polarity Conversion Joint
This machine has the polarity conversion; There are positive and negative connector on the front panel. When using solid wire with gas shielding, the polarity selection cable should be connected to the positive connector, the working clamp cable should be connected to the negative connector; When using flux-cored wire the polarity selection cable should be connected to the negative connector and the working clamp cable should be connected to positive connector.

The current can not keep stable during operation:
This situation may relate to the following factors:
The voltage of electric power network changes;
Serious interference from electric power network or other electric facilities.
Porosity in welds:
Examine whether the gas supply circuit has any leaks.
Examine whether there is contaminants such as oil, dirt, rust, paint etc. on the surface.

Attention

The precautions listed in this manual are intended to ensure the safe use of the machine and to protect you and others from harm and injury.
The design and manufacture of the welding machine power take full account of the safety, be sure to comply with the precautions in this manual, otherwise it will cause serious accidents.
Wrong use of welding machine power supply will cause the following kinds of different degrees of harm and injury. Please read this manual carefully to avoid or minimize such harm.
6.1 Welding Environment And Safety
Working surroundings
(1) Welding should be carried out in dry surroundings. The air humidity level should not be higher than 90%.
(2) The temperature should be between -10°C to 40°C.
(3) Don’t use the welding machines in sunshine or rain. Keep it dry.
(4) Don’t use the machines in the places of dust or corrosive air.
(5) MIG welding should not be carried out in places with god ventilation.
Safety norms
Over-voltage, over-current and over-heating circuits are built into the welding machine. It will stop working automatically when the input voltage, output current or internal temperature exceed the rated value. But if the machines are excessively used, such as with input voltage higher than the rated, the machine might be damaged. Please pay close attention to the following matters.
Keep good ventilation!
The welding machines work with high welding current.Normal air flow can’t provide the requirement of heat dissipation.
So the fans are installed as cooling system to ensure stable performance.
Make sure the ventilation windows are not covered or blocked. The distance between the machines and things around it should not be less than 0.3m. Good ventilation is good for welding performance and operational life.
Never over load!
Check the maximum rated current (according to the Duty Cycle chosen). Make sure the welding current is never higher than the rated value. Over current running will obviously shortens the operational life, and can even damage the machine.
Never over voltage!
The Input Voltage can be found in Technical data diagram.The auto-compensation function will keep the welding current in the rated range. If the input voltage exceed the permissible value, the machine will be damaged. Users should take protective measures in advance to avoid it.
Make sure earth connected before operation.
On the rear panel of welding machine, a screw for earth connecting would be found. It must be ground connected with cable whose section is bigger than 6mm2 before operation, to avoid accidents caused by static or electricity leak.
