Oxford Tig welder plus welding recommendations
Oxford plasma cutters best offers: Stick Welding — If you learned to weld years ago, you likely learned using an arc welder. Stick welding for many years has been the most popular method for most home-shop welding needs. This process uses an electric current flowing from a gap between the metal and the welding stick, also known as an arc-welding electrode. Stick welding is an effective method for welding most alloys or joints and can be used indoors and outdoors or in drafty areas. It’s also the most economical welding method and provides the ability to create an effective bond on rusty or dirty metals. However, this method is limited to metals no thinner than 18-gauge, requires frequent rod changing, emits significant spatter and requires that welds be cleaned upon completion. Stick welding is also more difficult to learn and use, particularly the ability to strike and maintain an arc. Arc welders are available in AC, DC or AC/DC, with AC being the most economical. It’s used for welding thicker metals of 1/16 inch or greater. These machines are a good choice for farmers, hobbyists and home maintenance chores.
OXFORD HYBRID chopper machines such as the MULTI-ARC models, CUTMAKER PLASMA, TIGMAKER & PULSE MIG models (I-MIG DP & S-MIG DP) offer a really sensible alternative to the inverter. They are still built around a rugged copper wound transformer but the hybrid chopper technology used in these works to give you superior welding performance, the lowest power consumption & the very high efficiency means the transformer is around half the size & weight of an older type machine. The electronics are simple & operate at the welding voltage level i.e. under 80V, there is only one PCB fitted & no microprocessor to cause software faults. So to sum up you get all the performance benefits of a good inverter but reliability is superb & you can expect a really long life span, equivalent to old type transformer machines, many times that of any inverter!

The arc is shaped like a cone, with the tip at the electrode and the base on the metal being welded. The closer the electrode is held to the metal, the smaller the base of the cone – but as you pull the electrode farther away, the base (and puddle) gets larger. If the puddle gets too large, gravity will simply pull it away from the base metal, leaving a hole. This is why thin-gauge metals are especially challenging for beginners. Perhaps the most important skill needed for TIG welding is moving the torch in a controlled manner, with steady forward movement, while keeping the gap between the tip of the electrode and the base metal consistently small – usually in the range of 1/8 inch to 3/16 inch. It requires a lot of practice to precisely control the arc length, keeping it as short as you can without allowing the electrode to touch the base metal or filler rod.
Many companies get completely “bogged down” in the paperwork required to run a business. But with today’s latest technological advances, there are items that can be a great help. For instance, Lincoln Electric offers something called ArcWorks software which can document procedures, create drawings everyone in the shop can access, keep track of welding operator’s qualifications, and many other things. Software such as this can be tailored to the individual company’s needs and provide great efficiencies and also eliminate mistakes. Adding Robotics or Hard Automation to the Operation: Today’s technological advances offer many options. Robotics can be justified when the volume of parts a company produces is so great that it can offset the monies spent on a robot. Robotics can also be considered if there are a number of different parts that are similar enough in nature to be able to be handled by the same robot. If robots are not justified, a company might determine that fixturing or hard automation could be used to increase efficiency or quality. One company incorporated fixturing and clamps to hold down a tank while the seam was being welded. In another case, an automotive manufacturer decided that automation was necessary because of the amount of parts and intricate angles and welding positions.
