Dont buy china!
Dont buy a china made unit. If u have probs with it service support is null. Any of the Big 3 are gonna be good, Hobart, Miller, Lincoln. Do know that Hobart & Miller are owned by the same parent company with ALOT of the models being pretty much the same thing with Hobart being less expensive. Miller being marketed more towards pro users and Hobart being marketed towards hobby users. Miller versions usually have slightly higher duty cycle and Hobart versions usually have slightly less duty cycle but little more AMPs than Miller version. Lincoln welders tend to cost more than Hobart/Miller. If going with a 110v MIG id recommend going with a 140AMP unit since its the most power any 110v welder can supply. Reason why I say 140AMP unit too is the fact that most are rated at 1/4 inch thickness on single pass and although u probably wont be welding much 1/4 inch material for gokarts, it is nice knowing if u do happen to need to weld that thick once in awhile ur machine is capable. Also note ur duty cycle increases when u run at lower power setting so figure u have a 140amp unit and a 90amp unit. Ur welding at 30 or 90amps the 140amp unit will be able to weld longer none stop then the 90amp and the 90amp unit welding at 90amps probably is only gonna be able to weld for 60 seconds at a time before u reach the duty cycle and have to let the welder cool for 8 minutes before u can lay down 60 seconds of bead again. lol. I own a Hobart Handler 140 and its frickin awesome. I made my own header for my Honda GX160 (easy) built a rear bumper and working on a swingout tire/gas can carrier for my freind and no problems. Only time I had a issue was that my buddies generator couldnt handle the welder. Also note that the bigger 110v machines can both do flux core and run inert gas to run solid wire. My machine came with the valves and everything ready to hook up a inert gas bottle out the box. If u want to spend a few hundred more u can go for a Dual Voltage MIG machine that will do up to 140amps on 110v and more amps, 200amps on 220v. I payed $499 for my HH140 and it came witha welding helmet, gloves and welding cap FREE and I got FREE shipping. Although spend the money for a autodarkening helmet. lol I dont want to spam the board by posting the company but Its not hard to figure who it is if u can use google. Also stay away from china mig wire. Any wire that says E71T-GS is pretty much crap. E71T-11 spec wire is a good all around wire. Lincoln Innershield 211MP & Hobart Fabshield 21B, Hobart RTP are good self shielding flux core and they are E71T-11 spec and can do MultiPass if u weld thicker metal. Also know if ur gonna do alot of sheetmetal ur gonna need gas and .023 tips if not ur gonna burn through the thin stuff. Medium guage metal needs .030 tips and wire and thicker stuff gonna need .035 tip and wire. .035 is pretty much the thickest wire that will run in a 110v machine. If u cant afford multipul tips and wire diameters id recommend just getting .030 and adjusting ur machine settings to make it work. Do know .035 wire is cheaper than .023 and .030. I have noticed the thicker the guage wire the cheaper it is of the same spool size. Cheaper 110v machines usually only can do 1 or 2lbs spools while the better 110v machines can run 1,2, or 10lbs spools. 1 & 2lbs spools are 4 inch spools and 10lbs spools are 8 inch. Hobart/Miller units come with a adapter to run all those diameter spools, Im sure Lincoln does too but not sure. Also note that welding wire is cheaper per lbs with bigger spools, kinda like buying in bulk. Hope this LONG post helped u somewhat. Good luck and have fun. Welding machine is a great tool to have and u can do sooooo much with one, not just build things but also to use for repairs.

The construction industry is responsible for the creation of all kinds of structures with varying sizes, levels of complexity, and uses. From simple, small structures such as family homes to large, complex ones like bridges, dams, and manufacturing plants. Structural integrity and durability are the most important considerations in this industry. This is why the construction industry employs a very large quantity of metals. In the United States alone, more than 40 million tons of steel are used annually in the construction industry. The majority of this quantity is used to create structural frameworks. This is where welding plays an indispensable role in construction.
Welding technologies are widely used in the construction industry, mainly for the fabrication of structurally sound metal frameworks by fusing various metals components. It is also used to create and maintain non-structural components. Some of the welding used for construction is pre-fabricated in a shop environment while other parts of the welding process are done on-site.
Applications of Welding in ConstructionConstruction comprises numerous industries, including transportation, oil, and gas, telecommunication, power, manufacturing, many others. The construction industry is very broad & diverse and is divided into three major sectors which differ by the type of structures they create. These sectors are Building, Infrastructure, and Industrial.
The application of welding is crucial to all three sectors.
Building ConstructionAs the name suggests, the building construction sector involves the creation of structures in which people can dwell and carry out their activities. This sector is further divided into residential and non-residential. Building construction mainly employs welding in the creation of structural frameworks from metal components. Welding is used for connecting steel I-beams, trusses, columns, and footers, to support the walls, roof, and floors of a building. These components are cut to shape and size, lifted into position, and welded together.
Structural welding is not employed as extensively in small buildings, as it is in high-rise buildings that require thousands of metal joints. Welding in building construction is also used for the fabrication of non-structural building components such as firewalls, stairs, handrails, and floor joists. Furthermore, welders work with other professionals in setting up various systems in a building. These include:
This sector is responsible for the creation of infrastructures such as bridges, dams, railways, stadia, water supply systems, highways, and wastewater management systems. The application of welding in infrastructure construction is mainly structural. This is because most of the structures created in this sector are megastructures that completely depend on structural reliable metal frameworks created via welding. Certain infrastructure such as bridges can be made almost entirely of metal. Others such as dams and water systems require a lot of pipe welding.
Industrial ConstructionFor more information, please visit builders warehouse welding machine.
Industrial construction covers all structures that are utilized industrially. Structures created by this sector hardly stand alone but are usually part of a large system of numerous components and structures that work together for specific purposes. Such systems include manufacturing plants, refineries, mills, power generation stations, and many more. Industrial construction is considered the most diverse sector within the field as it cuts across numerous industries. The applications of welding in this sector are as diverse as the sector itself. TIG welders are used for the fabrication and maintenance of structural frameworks, pipelines, industrial equipment, and support structures for large components.
Welding Technologies Employed in the Construction IndustryThe construction industry has a wide range of welding needs. Most existing welding technologies have one use or the other in the industry. Some of these and their uses are as follows:
The importance of structural integrity and durability in construction can hardly be overemphasized as structural failure can lead to a devastating loss of life and resources. Structures created weigh thousands of tons and are expected to last for hundreds of years. With the high strength and durability of weld joints, stakeholders in construction can rest assured that there&#;s nothing to worry about from the point of the framework.
Productivity is crucial to saving costs, resources, and time on any construction project. Productivity in a project is dependent on the efficiency of the processes involved. In terms of advancing construction efficiency, welding is at the forefront. While welding itself is a highly efficient process when using the right equipment, several other technologies have been incorporated into the process to make it even more efficient. Some of the technologies used in welding that are particularly beneficial to the construction industry are as follows:
This technology saves builders thousands of dollars and increases speed and productivity by eliminating the need for a welder to move to and from a power source to make necessary adjustments during welding. This is particularly helpful in high altitude welding where the actual welding may be 100s of meters above the ground where the power source is located. Some of the solutions that make up ArcReach include Cable Length Compensation (CLC&#;) which automatically adjusts the delivered voltage based on the cable length to ensure that the set voltage is always supplied; and Adjust While Welding (AWW&#;), which allows the operator to remotely adjust weld settings right from where they are working.
Types of automation equipment that increase efficiency and accuracy include automatic wire feeders, welding manipulators, turning rolls, and welding positioners which are used to hold and rotate the pipe or other weldment.
Some welding projects require more than one welding technology at a spot. It is stressful enough to switch equipment not to imagine doing this at heights where you would need to ascend and descend repeatedly. Multi-process welders eliminate this problem by combining various welding technologies into a single compact unit. In addition to all these, another factor that boosts productivity is the portability of welding equipment. This is appreciated when work has to be carried out over rugged terrain, at height, or in relatively small spaces.
The construction industry has a wide range of fabrication requirements. One of the numerous reasons why welding is indispensable in construction is its flexibility. For any size, work environment, or material, there is a suitable welding technique. For example, 5 cm diameter pipes can be welded as good as 50 m long beams and columns. Also, the various metal grades used in construction are all compatible with one welding technology or another.
Cost-effectivenessCompared to many other manufacturing processes, welding is relatively cost-effective. To save even more, contractors and other industry stakeholders can simply rent high-quality TIG welders equipment, saving thousands of dollars on capital spending.
