• A low-hydrogen iron powder type electrode that produces high quality x-ray welds.
• It can be used in all positions on AC or DC reverse polarity welding current.
• Recommended for welding medium grade carbon steels where no preheat is used, and on cold rolled steels normally exhibiting excessive porosity when welded with conventional electrodes.
• Typical applications includes low-alloy structurals, low, medium and high carbon steels, offshore rigs and power plants, steel structures and tack welds for tubular wire applications.
• H4 electrodes have low hydrogen content which make them resistant to cracks and allows them to form stronger welds for a longer period of time.
• Ideal for welders in small shops, farms, artists, hobbyist, small repairs, and DIY welders
