What wire diameter is the Lincoln MetalShield MC-706 Metal-Cored Welding Wire available in?

The Lincoln MetalShield MC-706 Metal-Cored Welding Wire is available in .045, .052, 1/16 diameter. Wire diameter selection depends on base metal thickness and travel speed requirements: .023 in suits thin sheet metal (up to 3/16 in), .030 in is versatile for 1/8–1/4 in, .035 in is the most common all-purpose diameter for 3/16–1/2 in steel, and .045 in or larger suits heavy plate and high-deposition applications.

What shielding gas or flux type does the Lincoln MetalShield MC-706 Metal-Cored Welding Wire require?

Shielding gas selection affects arc stability, spatter, bead profile, and penetration: 100% CO2 gives deep penetration and good bead wetting but more spatter; 75% Ar/25% CO2 (C25) is the most popular general-purpose mix, balancing penetration, spatter, and bead appearance; higher argon mixes (90/10, 95/5) suit spray transfer at higher amperages. Match shielding gas to your wire alloy and welding parameters.

What is the deposit strength of the Lincoln MetalShield MC-706 Metal-Cored Welding Wire?

For E70C-6M: Deposit tensile strength for mild steel solid MIG wire (ER70S-x) is approximately 70,000 PSI (483 MPa) minimum. For stainless filler metals, the deposit strength matches the base alloy grade. For flux-core wires, strength and chemistry vary by classification — refer to the AWS classification on the package for the exact mechanical property requirements.

What spool size is the Lincoln MetalShield MC-706 Metal-Cored Welding Wire available in?

The Lincoln MetalShield MC-706 Metal-Cored Welding Wire is available in 50 lb, 500 lb, 33 lb spool/coil sizes. Smaller spools (2 lb, 10 lb) fit most hobby and light commercial feeders. Larger spools (33 lb, 44 lb) are standard for production welders with 12 in spool capacity. Drums and coils (250–600 lb) are used with bulk drum feeders for robotic and high-production applications.

How should I store the Lincoln MetalShield MC-706 Metal-Cored Welding Wire to prevent weld quality issues?

Store MIG wire in a clean, dry location away from humidity. Moisture absorption causes porosity in the weld — mild steel wire is particularly susceptible. If wire has been exposed to moisture, it may show surface rust; lightly rusted wire can sometimes be used but should be wiped before feeding. Flux-core and low-hydrogen electrodes require stricter moisture control than solid wire. Keep spools in their original packaging or sealed containers with desiccant packets when not in use.
