Metal-cored wire can weld thin materials without burn-through because it lacks a "deep finger" of penetration. Also, spray transfer requires less amperage with metal-cored wire. On thinner metals (1/8 in. or less), metal-cored wire may let you switch from short-circuit to spray transfer to improve travel speeds, bead appearance, and bead quality.

Aluminum Drive - You won''t find the welding wire fed through some plastic drive system. No! Inside the Hobart 140 you''ve a, quality Aluminum drive feeding your welding wire. The steady feed of your MIG welding wire helps you get decent welds. Dual Gauge Gas
When welding with metal-cored wire, the spray transfer process is used. This process creates tiny filler metal droplets that deposit in the weld puddle and generate little to no spatter. Because the current travels through the outside metal sheath, the wire
How to MIG Weld - Welding Techniques For Beginners
MIG welding is often known as Gas Metal Arc Welding or wire welding (which is the colloquial term for it). It is a popular form of welding which is capable of welding (for maintenance and repair purposes) anything from 24 gauge materials to those of a half-inch thickness.

FAQ | Lampert Werktechnik GH
The point of break must be prepared specially for welding: The edges are filed into a V shape and only the remaining material that is directly touching is welded together. The joint that results from this is continually filled with filler material (welding wire).
Plant Engineering | Mild steel welding: find the right filler
When welding mild steels, two common gas-shielded flux-cored wire options are E70T-1 for flat and horizontal welds and E71T-1 for all-position welds. Offering similar or higher deposition rates than metal-cored wires, E70T-1 filler metals are well-suited for thick, heavy weldments requiring a lot of weld metal.

Wire Feed Welding - EzineArticles
The basic idea behind wire feed welding is that you use a welding wire that continually feeds through a MIG welding gun when you squeeze the trigger. This is a continuous welding process. As long as you keep your finger on the trigger and the welding wire touching the base metal you will be able to wire feed weld all day.
With metal-cored wire, the contact tip to work distance — the gap between the welding gun and the base material — can be slightly longer than it is with solid wire. The recommended gap for the best performance and arc stability with metal-cored wire is between 1/2 inch and 1 inch, depending on wire …
7 MIG Welding Mistakes and How to Avoid Them | Bernard
Because flux-cored wire is softer — due to the tubular design and flux inside — it requires using a knurled drive roll that has teeth that can grab the wire and help push it through. Knurled drive rolls typically should not be used with solid wire, since the teeth can cause shavings to break off of the wire, clogging the liner and creating resistance in wire feeding.
