E7018
Diameter × Length (mm)
2.5 × 350, 3.2 × 350, 4.0 × 400, 5.0 × 400
Package
20kg/Carton
EASYARC™ 7018 is an iron powder low-hydrogen type electrode for all-position welding of mild and low alloy steels. The easily controlled arc of EASYARC™ 7018 makes it easy to use on DC polarity.
EASYARC™ 7018 offers excellent mechanical properties, high efficiency and high impact values at -30°C. It is also easy to strike and restrike.
ADVANTAGE LINCOLN
All controlled hydrogen electrodes will perform optimally when they are dry. Unopened Lincoln PERMAPACK's provide excellent protection against moisture pick-up in good storage conditions. Should re-drying be necessary, remove electrodes from the packet / container and spread thinly and evenly on racks in a ventilated oven. For electrodes that have had a short or mild exposure to the atmosphere then re-drying at 572°F(300°C) for 1 hour will be sufficient. For electrodes that have been exposed to longer or more aggressive conditions or for critical work re-drying at 572-662°F (300- 350°C) for 1-2 hours is recommended. After re-drying electrodes should be stored in a hot box.

TYPICAL APPLICATION
EASYARC™ 7018 is a multi-purpose electrode with excellent operator appeal. EASYARC™ 7018 is excellent for welding of mild and low alloy steel, which is used for bridges, buildings, ship building, pressure vessels, etc. EASYARC™ 7018 can also be used for the construction or repair of earth moving, farm and mining equipment.

GUIDELINES FOR USE
- All water, rust and oil should be completely removed from base material to prevent cracking and blowholes.
- Backstep method should be applied to prevent blowholes and pits during starting. Arc length should be kept as short as possible during welding.
- If weaving is required, the width should not exceed 3x the diameter of the electrode.
