An incredible wire, and the nicest welds you will ever see. It’s genuinely a joy to weld with, and we’ve tried it on every and all type of mild steel application. A pure quality product (and as good as MIG welding gets).

Bulk pallet (56 reel) rates available upon request and in stock.

To be used in flat and horizontal only.

ESAB Coreweld 46 LS is the premium equivalent of Lincoln Electric Outershield MC710 metal-cored MIG wire, and is designed for the below reasons.

Ultra clean, no spatter, and no silica
A true production wire for lots, and lots of fast, clean and perfect welding
Superior fusion at the root joint and sidewall penetration front and back (does not blow through)
The wider welding arc produced means larger gaps can be bridged than with solid wire (great for shipbuilding and often needed)
A much easier wire to weld with and ideal for difficult plating prep situations
Super smooth spray transfer (welds like liquid metal is pouring out of the end of the shroud)
Flat welds with deep penetration and wetting into plate for superior fusion
Very high deposition rates (quick welds). This dramatically reduces weld time, reduces heat input in the Heat Affect Zone (in and out quicker), and massively increasing productivity
This wire produces very strong welds, and used on high strength 355 to 460 MPa mild steels

ESAB Coreweld 46 LS is not recommended for vertical-down welding, as metal-cored wires are generally designed for flat and horizontal positions due to their high deposition rates. Vertical-down welding with a metal-cored wire will result in a runny weld pool and loss of control, unlike gas-shielded or self-shielded flux-cored wires which create a slag to support the puddle.

Metal-cored wires offer many more advantages over solid wire. Since metal-cored wires carry the current on the outer sheath, current densities are considerably higher than weld current being spread across the entire cross-sectional area of solid wire. As a result, the metal-cored arc tends to be softer and more controlled, with reduced tendency to burn through.

Product Description

Always use with ‘-‘ negative earth.
4x roll feeder needed with knurled flux-cored serrated drive rollers.
3mtr torch preferable because it’s a soft wire (unless it’s an ESAB Robust Feed which can feed with 4mtr torch)
1.6mm Polyamide Teflon liner needed for 1.2mm wire.
Sometimes a 1.4mm contact tip is also advised if used on an air cooled torch (prevents snagging).
88% Argon / 12% Co2 BOC M21 shielding gas required for best results.

DO NOT USE ON SYNERGIC MODE (unless it’s the Warrior Edge which has a synergic setting for Coreweld 46).

DO NOT USE ON PULSE MIG MODE.

Keep the feed speed low and amperage high, and this wire floods into a prep like liquid metal… and fast.

For best results welding 6mm to 6mm plate for example, use on a manual MIG, set to the polarity to 75%, wire feed speed @ 6mtr per min, and 24.5 Volts.

Why Coreweld 46 LS is not for vertical-down welding

Lack of slag support: Unlike flux-cored wires, metal-cored wires do not produce enough slag to support the molten weld pool in a vertical-down position. This leads to the weld metal running out, making it impossible to create a proper joint.
High deposition rate: Metal-cored wires are designed for high productivity in flat and horizontal positions, which is not suitable for out-of-position welding.
Incorrect process: The metal-cored process is optimised for high deposition rates and penetration, which is not what you need when trying to maintain control in a vertical-down scenario.

Alternative for vertical-down welding

For vertical-down welding, a gas-shielded flux-cored wire (FCAW-G) is the correct choice. This type of wire has a flux coating that solidifies quickly and forms a shelf to hold the molten metal in place
