804036 BASIC ELECTRODE 2.5 X 300 CF 119 PIECES TELWIN

Telwin 804036: Professional Basic Electrodes for High-Tension Joints

Model 804036 identifies a professional supply of basic electrodes (also known as E7018 according to the AWS regulation). These electrodes were developed by Telwin to ensure impeccable results in steel welding, where the mechanical strength of the weld is a fundamental requirement.

Coating Characteristics and Deposit Quality

The basic coating formulation offers superior technical advantages compared to rutile models:

• Material Purification: The coating exerts a purifying action on the base material, producing clean and structurally sound welds.
• Hydrogen Free: The chemical composition prevents hydrogen contamination in the weld pool, ensuring maximum mechanical integrity.
• Positional welding: They are ideal for vertical, overhead and difficult angle welding, maintaining total control of the weld pool.
• Tough slag: The slag produced is hard and protective, ideal for high-quality rework after mechanical removal.

Operating Data and Recommendations for Use

To achieve maximum performance, it is necessary to use inverter power sources in Direct Current (DC) with reverse polarity (connecting the electrode holder to the positive pole). The presence of fluorite in the coating requires the skill of an experienced operator to maintain a very short and stable arc throughout the operation.
