DCEP, or Reverse Polarity is the standard polarity for MIG and for Stick welding. In MIG, if it uses gas only, without a flux or metal core, it will require electrode positive. Dual shield and metal core can vary.
If you are confused by welding terminology like “Reverse Polarity” and “Straight Polarity”, this blog will be a basic primer to help you understand the basics of polarity and where and how to use them. Every welding process has a preferred polarity. This means that the lead or cable connected to the gun, torch or electrode holder is connected to the receptacle with the stated polarity. Usually this will be stated as a + sign or a – sign.
Sometimes it will simply be stated as work and torch, with or without a polarity designation to reduce the chance of confusion.
As a part of any tech information that you will find on any welder, one of the most prominent technical specifications listed should be the declaration of duty cycle. This is usually found on the front or rear of the welder. Historically, duty cycle has been an indicator of the soundness of a machine for a particular work application. The standard of 60% has long been considered to be a professional, industrial type of welder, whether it is MIG, TIG or Stick.
If you’ve always used a MIG welder, and never attempted to stick weld, it is likely something that is somewhat of a intimidating process. It may even seem archaic and out of date. But it is hardly the case. As far as you skill teaching, even for MIG welding the stick process will always be a great tool to teach the basics of welding. One of the best skills that stick welding teaches is probably the skill of patience.
Regardless of the welding discipline the subject of more controversy and opinion is the subject of manipulation, whether it is the torch or filler manipulation. For stick welding purposes, it is referred to as electrode manipulation. Electrode manipulation is also called weaving. Weaving is movement of the welding rod in a particular pattern. There are numerous possible weave patterns that can be used including figure eights, zig-zag, J patterns, crescents , circles, cursive e’s, whipping, V patterns and more. Pattern selection depends upon individual preference and applications.
While learning to stick weld, the most common issue that people have is learning to maintain a proper angle, or rather we should say proper angles, because there are multiple angles to be considered when holding an electrode. When stick welding, the reference point when discussing angles is perpendicular to the metal, or a 90 degree angle. For example, in stick welding the electrode should be held at a 10 degree angle to the direction of travel.
In stick welding, there are multiple critical things that are going on at the same time that you eventually learn to pay attention to without thinking twice about it. But at first it may be like patting your head and rubbing your stomach if you are not coordinated or not used to doing several different things involving manipulation and concentration at the same. It’s not something to be concerned about though, as practice will eventually help bring all these things into focus at the same time and it will become second nature.
If you are learning to weld, and wish to master all disciplines of welding eventually, you will probably want to begin with one process, and learn it before proceeding to the other disciplines. If you are wanting to do this, then consider learning to Stick weld first. There are a lot of people who would like to ignore this facet of welding, but being able to stick weld is a not an outdated process and is not going anywhere for some time to come as it still excels in providing economy, portability, versatility and capability.
Everlast provides a variety of welding products, including stick welders, TIG welders, MIG welders, wire feeders, welding consumables, plasma cutters, water coolers, welding protection equipments, guns and torches, and other accessories.
Accessories and Parts
Everlast offers a wide variety of welding parts and accessories.
Consumables are important components for manufacturing industries and the overall welding process.
Guns and Torches
There is a variety of welding equipment, which includes a wide range of guns, gears and torches. Each piece of equipment serves a different purpose. For example: MIG welding will require different equipment from plasma cutting processes.
Helmets and Safety
Investing in the right welding helmet is a smart and convenient way to enjoy added protection. Still, welding is a potentially dangerous activity, forcing welders to avoid burns, electric shock, eye damage, poisonous fumes, and overexposure to ultraviolet light and radiation. Everlast safety helmets are thus a necessity for welders.
