The ZipweldersTM are considered one of the most advanced shear welder in the world today. These fully automatic welding machines were developed with an intention to reduce the operator involvement and increase mill uptime by reducing weld failures. The ZipweldersTM are designed for use on either start/stop or continuous lines like pickling lines, tube/pipe mill, coil buildup, galvanizing lines, and annealing and pickling lines. Zipwelders are used in a variety of applications such as stamping, tube/pipe mill, and many types of steel and stainless steel process lines. These machines can also be used for welding a wide range of alloys including stainless steel, carbon steel, copper, and aluminum.
The modern day RCM Zipwelders make use of some of the most advanced welding methodologies such as Tungsten Inert Gas (T.I.G.) welding, Plasma welding, Metallic Inert Gas (M.I.G.) welding, and last but no the least Laser Beam welding. The uniqueness about the Zipwelders is that they can shear and butt weld a variety of materials at varied range of thickness be it 0.15mm (.006”) to about 25mm (1.00”) and as wide as necessary. With the advent of new technology, newly developed Zipwelders machines can weld any type of weldable material, and have the capability to weld metals up to 2,400mm wide.
Another major example of innovation in ZipweldersTM is the ME 500-28 Zipwelder™. This Zipwelder is a computer operated automatic welder, equipped with an exit pinch roll. The ME 500-28 Zipwelder™ has been designed in such a manner that it can cut through a steel coil end up to 12.7mm (.500”) thick and 700mm wide (28”) from a steel coil. When operated in automatic mode, the trailing coil end automatically stops in the shear opening, whereas the exit side guides center the strip automatically, allowing the exit weld clamp to close down automatically. The operator feeds the leading steel coil into the Zipwelder™, and then the entry sides and entry weld clamp closes. The specialty of Zipwelder™ is that it automatically shears the two coil ends, and automatically makes an MIG weld based on the selection as per the on-board computer which controls not just the weld gap, wire speed, weld speed, but also the welding voltage. As with shear welder, these ZipweldersTM can be similarly custom designed, as per the requirement of the customer.

you may want to do a search on that (google). That may give u the help u need. Good luck!
mig welders need a shield gas unless u use flux core wire.
the best way to get a nice bead id to set your heat, and turn up the wire feed speed,…..strike an arc and turn down the wire feed till you get a nice bead with little splatter

glad you asked, Mig welding is really a simple task if you can already stick weld. what you see is what you get with a mig. follow the following process and you'll do great.
if right handed hold the handle slightly to the left just enough to see the wire sticking out of the nozzle, weld to the left in an overlapping circular pattern usually between 1/4 and 7/16 wide the lens should be sufficient if for arc welding. a quick practice on scrap metal should ease your concerns quickly. you will see the deposited weld in the lens and no chipping needed
Hope you are not using pure argon (just a wast of money for pure). You should be using a 75/25 mix of argon/co2. The shielding gas shields the molten metal from the atmosphere, more so oxygen and nitrogen to prevent porosity, and reduce the chance of cracks. To rent a tank you should call a local welding supply for the prices as the price varies quit a bit by location. I am in Ohio so a price I would give you would not be true for your location.

There is a big difference between MIG and TIG welding, in both the process, and the skill level required of the weldor. They really are two different processes altogether, and the MIG is the much easier of the two.
There is much to read on the web, including some great information at the Miller and Lincoln websites. They can give you a pretty great overview of TIG welding. But, as with many skills, it takes hands-on practice as well as study, to be successful.
If your fiance has ever welded with a gas torch, he might already have the skills he needs. Unlike a MIG welder, a TIG does not feed an electrified filler wire for you. You are in control of a separate heat source (the torch) that you must manipulate in order to melt the base metal together, while adding the filler by hand to the molten puddle you're creating. It's the same way a gas torch works, just with electricity, rather than gas, as the heat source.
The tricky part comes in learning how hot to make the puddle, how much heat to apply (with a foot or hand controller), and how to coordinate the filler at the same time. Quite often, TIG welding involves metals like aluminum or stainless, which have their own quirks that need to be considered. It's by no means impossible to learn all of this…and it can be a very valuable skill to have, often paying higher than MIG welding jobs.
If your fiance shows this prospective employer that he is a professional who takes pride in his work, has studied the subject, and is willing to learn, he may get his foot in the door and start down a new path on his welding career. I wish him the best. Study all you can, and if you know a buddy who is good with the Oxy-Acetylene torch, go visit him right away for some practice!
Best of Luck!

If the nozzle is arcing it means the insulator between the nozzle and gas diffuser is probably shot. You will have to either replace the insulator or make sure you don't touch the work piece.
Arcing outside the weld zone is not good, can lead to inbrittlement and cracking.
Oh, and good job on buying a miller…i hate it when people buy crap gear and expect miracles(or ask me to perform them with their junk welder)
First off, are you a good welder? If you have limited experience, you will not get good weld penetration with a MiG welder. Also if you use one of the cheap welders that you can buy at Lowe's or auto parts stores, they don't produce enough power to get a deep penetrating weld.
MIG means machine inert gas. Those cheap welders are called MiG but are just wire feed welders and not MiG. You must use gas to get a good weld. A cheap gas to use if you are a good welder is carbon dioxide. The weld is good only if you are very experienced. Next you can use 75/25 gas mix which is 75 % argon and 25 % carbon dioxide. Doesn't take as much skill and produces a reasonable weld. For a top job, use 100% argon. It costs a little more but does so much more.
If you buy a MiG, get a good one in the $2000 dollar range, such as a commercial Lincoln, Miller or Hobart. Go to welding school at your local Vo-tech and practice, practice, practice. Once you learn, you can weld car doors, bodies, exhaust, frame or anything else you so desire. As a good MiG welder, you can get a top paying job and be set for life. I prefer a auto darkening helmet when I weld. It makes learning so much easier.
Consistency, quality, and operating cost. Remember, you don't need highly trained welders, just machine operators to run them.
