Welding direction
As the appearance and properties of the deposited weld metal varies broadly in accordance with thewelding conditions, select the welding conditions carefully.The welding conditions and their effects are shown in Fig.1.
If it is leaned to opposite to welding direction① Weld metal width becomes narrow.② Reinforcement of welds becomes high.③ Penetration becomes deep.
If it is too large① Spatter loss becomes high.② Arc becomes unstable.③ Penetration becomes shallow.
It becomes long (wire feeding speed is fixed)① Welding current decreases.② Arc length becomes long.③ Penetration becomes shallow.
If it is too high ① Porosity appears.If it is too low;① Nozzle is prone to clogged with spatters.② Long time welding is impossible.③ It is difficult to see the welding line..
If it becomes long① Weld metal width becomes wide.② Reinforcement of welds becomes
low.③ Penetration becomes shallow.④ The undercuts are prone to appear.
If much oil and rust are on it, porosity appears.
If the gas flow is little or the wind is strong, porosity appears. The transfer mode of molten drop varies in accordance with the type of gas.

The large-packaged wire reduces the time loss for changing the wire, which is particularly effective forrobotic welding and other automatic welding.
① Please load and fix at pallet when conveying. Use cart to keep on the horizontal status whentransporting separately.
② Please clean up the inside of cable once or twice a week for smooth supply of wire. (Use high pressure air)
③ Use the press board in the pack as equipped status when supplying. Do not lift up or pull out while using, it may cause the tangle.
④ Before use, remove and pull out silica-gel to remove the moisture in the pack or spring for fixing toprevent trembling during transfer.
⑤ The pack might get humid, so keep it at the dry place.
