Welding 101: Getting Started With MIG Welding Basics
The same goes for the wire type (as we listed above), if you’re welding mild steel you will want to use a steel wire, stainless steel, a stainless wire, and aluminum use aluminum wire. This ensures your wire has a melting point as close to your working material as possible and most closely matches it from a metallurgical standpoint.
Beginners Welding Tips for Machines / A short guide | …
Similar to how ARC welding rods work this is accomplished by using the flux that is filled inside the welding wire used. You see the weld must still be protected from oxygen & moisture in the environment, so flux is filled inside the wire to shield the heated weld.

Learning to Weld : 19 Steps (with Pictures) - Instructables
It shows some welding on heavy stock well beyond the normal capability of my 125 amp. wire feed welder, yet it worked because I preheated the joints with a MAPP gas torch before welding. That gave my welder a boost and extended its capabilities.
3 Welding Processes Explained | Westermans Blog
MIG Welding Other name: Gas Metal Arc welding Abbreviations: MIG or MAG or GMAW It uses a shielding gas along the wire electrode, which heats up the two metals to be joined. This method requires a constant voltage and direct-current power source, and is the
MIG vs TIG Welding - Beginner Welding Guide
MIG vs TIG welding – The Basics It is always striking to see a near-perfect TIG weld on a finished product. A near-perfect TIG weld looks like a stack of dimes. The evenness and accuracy of the weld bead is an indior of the skill level of the welder. Nevertheless, a
Mig Welding Tutorial
And if the wire gets stuck then what happens is that the feeding wheel keeps feeding the wire and you have a problem because the wire will get all jammed up in that area. At this point you must stop welding so that you can get the tip unjammed, cut the wire off, and then re-feed the new wire all the way through your cable, which is a massive waste of your time.
Flux-Cored Welding: The Basics for Mild Steel
2010/6/1· Weld outdoors with ease Self-shielded flux-cored welding can be an excellent process to use for welders of all skill levels who frequently need to weld outside or on dirty material. Self-shielded flux-cored welding is a wire welding process in which a continuous hollow wire electrode is fed through the welding gun into the weld joint.
Which cored wire is the best for welding without …
On the other hand, cored wire is extremely insensitive to influences such as wind in outdoor appliions. After the process has already been explained in detail in other articles (cored wire welding without gas), in this article we clarify the question of the cored

Understanding MIG Welding Nozzles - ABICOR BINZEL
When welding zinc or zinc-coated metals, conical welding nozzles are the recommended nozzle shape to use. The reason being is because zinc produced very large and explosive spatter when being welded, and the clearance provided by the base of the conical welding nozzle allows for it to be reamed more effectively than other nozzle shapes assuming you use a two-stroke reaming process with air blast.
