There are many different types of welding, but some are much more common than others. Besides, there are several factors that should influence your buying decision when you are in the market for used welding equipment.
You will have to decide on the brand of the equipment - Miller, Lincoln, Esab or Hobart from amongst the many. Should you opt for a multi process machine capable of TIG, MIG, Flux Core, and stick welding or buy different machines for each of the process. Would you want oxy-fuel cutting outfit or plasma cutter and more importantly, whether you need air compressor or electric grinders.
Many professionals opine that multi process machines are unwieldy and cumbersome and you should opt for it only if you have that type of regular work to warrant its purchase.
For your main TIG welding machine and MIG welding, you may visit e-Bay or Craigslist where you will find several bargain offers. If you have restricted floor space, you can opt for a foldable welding table that can be hung on the wall saving you a lot of moving space.
As regards electric grinders you can easily obtain one or two straight grinders as also 4 1/2 inch angle grinders along with a variety of consumables. If you have a regular workshop away from your home, then go for an oxyfuel cutting, welding, and heating kit. You will never regret this purchase.
It is strongly recommended that you have two argon cylinders preferably owner cylinders and not leased ones. Keeping a spare owner cylinder will provide you the required time-gap in getting your main cylinder refilled.
Please know that nearly 500,000 employees in the United States work in factories that do welding work. This means there is a lot of used welding equipments around for sale. Because of the wide choice for used welding equipment - people who are hunting for the equipment should do plenty of research before finally buying.
A useful tip for getting good deals on used welding equipments is to search the local Craiglist listings where you will come across some fabulous offers. However, if buying the welding equipments online, you must insist on seeing true pictures of the welding equipment - particularly if you are planning to buy an expensive item like a Miller Syncrowave 250 or 300. If a seller refuses to provide a real photo, then negotiate no further and call off the deal.
There are several online auction sites where you can find some really good welding equipment. Of course, the most resourceful auction site is eBay. Then there is UBid that may not be as popular as eBay but it can throw some surprise offers. More importantly, when you buy used welding equipment on the Internet, check what kind of certifications and approvals the company that sells them has.
