1, Premium E7018 Classification: Low-hydrogen iron powder rods for high-quality, X-ray acceptable welds in demanding structural applications.
2, Versatile All-Position Welding: Engineered for use in all welding positions (flat, horizontal, vertical, overhead) with AC or DC reverse polarity.
3, Superior Arc Performance: Ensures a steady arc, low spatter, quick re-striking, and high deposition efficiency for consistent results.
4, Prevents Porosity Issues: Recommended for welding medium carbon and cold-rolled steels that often exhibit porosity with conventional electrodes.
5, Structural Grade Application: Ideal for low-alloy structurals, offshore rigs, power plants, and general steel fabrication.
Q: Can I run these 1/8" rods on a standard 120V wall outlet?
Q: Can I run these 1/8" rods on a standard 120V wall outlet?
A: Highly unlikely. These rods require 115A-165A of output. Most 120V welders max out at 90A-100A on a standard circuit. For these 1/8" rods, you generally need a 240V welder to prevent the rod from constantly sticking.
Q: What is the best polarity setting for these rods?
Q: What is the best polarity setting for these rods?
A: For the best results, use DC+ (DCEP / Electrode Positive). This provides the smoothest arc and the best penetration. While they can run on AC, you will experience more spatter and more frequent arc-outs.
Q: Do I really need a rod oven to store these?
Q: Do I really need a rod oven to store these?
A: If you are doing critical structural work (like a trailer hitch or a bridge), yes. Once the seal is broken, they start absorbing moisture. For general farm repair or non-critical hobby use, a sealed plastic O-ring canister is usually sufficient for most American climates.
Q: How do I restart a rod that I’ve already used half of?
Q: How do I restart a rod that I’ve already used half of?
A: 7018 forms a "glass" crust over the tip after it's been used. Do not just try to strike it like a match; you must pinch the tip with your gloved hand or tap it against a hard surface to break that glass crust off and expose the core wire.
Q: Why is my weld look "worm-holed" or porous?
Q: Why is my weld look "worm-holed" or porous?
A: This is almost always caused by one of two things: 1) Your arc length is too long (keep the rod very close to the metal, almost dragging it), or 2) The rods have absorbed moisture from the air.
Q: Can I weld over rust or paint with E7018?
Q: Can I weld over rust or paint with E7018?
A: It is not recommended. 7018 is a "clean metal" rod. If you weld over rust, the low-hydrogen properties are neutralized, and you will likely get porosity. Use a grinder to get to shiny metal before using these rods.
