Used my brand new Rossi 130 a gasless mig welder & after 10 minutes the wire feed stopped,
The only things that come to mind after your checks are a spool not set in completely, a stripped spool or a spool drive shaft failure of some kind.
so...make surenthe spool is not stripped, its seated all the way and if so is the drive shaft for the spool and/or feeder pulleys all moving. If nothing is moving anywhere but you hear the actuator motors turning inside you have a warranty issue.

What is Welding Electrode?
An electrode is a coated metal wire. It is made of materials that are similar to the metal being welded. To begin, there are consumable and non-consumable electrodes. The electrodes in SMAW, also known as a stick, are consumables, which means they wear out during use and melt with the weld.
TIG Welding Electrodes are non-consumable, so they do not melt and become part of the weld. Electrodes are continuously fed wire during GMAW or MIG welding. Flux-cored arc welding necessitates the use of a continuously fed consumable tubular electrode containing a flux.

What is the difference between TIG & MIG welding?
MIG welding is also called Metal inert gas welding, gas metal arc (GMAW) welding. MIG welding uses an arc of electricity that creates a short circuit amidst a constant anode and a cathode. The short circuit produces heat and a non-reactive gas. This melts metal, enabling it to be mixed together. After the heat is removed, the metal cools down and then solidifies, creating new fused metal.
MIG wire is used in MIG welding. Tungsten inert gas (TIG) welding utilizes a non-consumable tungsten electrode that produces the electric arc for the weld. Unlike MIG welding, TIG welding does not require additional metal to be added.

Which type of dissimilar welding materials combination is good for welding?
Dissimilar welding refers to the process of connecting materials with different alloys through welding. The filler material and both metals need to be evaluated before choosing the best way to connect the metals.The type of welding typically used for dissimilar metals is fusion welding, which welders also use for joining similar metals. In some instances, a welder may need to determine another method for joining dissimilar metals. For all these types of joining, the welder will need to consider:
1. The composition of the intermetallic layer.
2. The unmixed zone (UMZ) of base materials that did not combine into the intermetallic layer.
3. The heat-affected zone (HAZ)

Difference between mig welding and arc welding?
Arc welding is any welding process that uses electricity, which includes MIG, TIG, and SMAW. SMAW Shielded metal arc welding is most commonly referred to as stick arc welding. In SMAW welding the stick electrode contains a flux that keeps the atmosphere from contacting and contaminating molten metal. It is a good choice for welding thicker metals. It is a manual process, that is hard to get a hand of. yet once done. MIG welding is a semi-automated process that is a much better option to use on thinner metals. It is easier to get hang of than SMAW welding. A welding
MIG wire is used in the MIG welding process. TIG welding is the hardest as compared to SMAW & MIG welding. It is capable of producing an autogenis weld which is one does not use any filler. These are some differences in arc welding processes.
What is the difference between overlay welding and hard facing?
Hardfacing welding is an overlay i.e to completely cover the surface such as applying an overlay to a worn or damaged shaft. Overlay welding is normally done with a machineable alloy that is close to or very compatible with the original alloy. Hardfacing is typically not normally done as a complete overlay but rather placed only at wear point or it is applied to surfaces with the random arrangement.
Hardfacing electrodes are specially used in hard facing.
