What is electrode holder in welding?
2. 3 Electrode Holder – The electrode holder connects to the welding cable and con- ducts the welding current to the electrode. The insulated handle is used to guide the electrode over the weld joint and feed the electrode over the weld joint and feed the electrode into the weld puddle as it is consumed.
What are the electrode holder classifications?
There are three types of electrode holders available: the 200A, 400A and 600 A. Range Welding Cable sizes 35mm2, 50mm2 and 70mm2.
What is the specification of welding electrode?
The number E6010 – indicates an arc welding electrode with minimum stress relieved tensile strength of 60,000 psi; is used in all positions, and reverse polarity direct current is required….
| Digit | Coating | Weld Current |
|---|---|---|
| 0 | * | * |
| 1 | Cellulose Potassium | ac, dcrp, dcsp |
| 2 | Titania sodium | ac, dcsp |
| 3 | Titania potassium | ac, dcsp, dcrp |
What is the use of electrode holder?
An electrode holder is a device that is used to hold the electrode during the welding process. It is a clamping device that holds the electrode secure enough to enable you to weld in a variety of positions. They come in many different sizes and current capacity.
What is the function of electrode in welding?
When joining two pieces of metal together, electrodes are used to create an electric arc. The two metals heat and melt, fusing together in a stronger bond. Depending upon the welding process, the electrode is either consumable or non-consumable. It must be chosen very carefully for a job.
What are the two parts of electrode?
Electrodes are conductors by which electrons flow through to generate a current. There are two types of electrodes, cathodes, and anodes.
Is the electrode holder positive or negative?
Stick electrodes are generally run with a positive polarity (DCEP). With this setup, your electrode holder (stinger) has a positive current flowing to the stick electrode (also just called a “rod”). Your ground lead will be attached to the negative terminal of your machine.
What is the function of electrode cable?
What is Welding Cable? Welding cable is designed for use in electric arc-welding machines to power an electrode, a specially designed metal rod, that conducts a charge. The charge carried by the electrode is needed to produce an electric arc, the heat source, between the electrode and the metals being welded.
What is the name of the electrode holder?
An electrode holder, commonly called a stinger, is a clamping device for holding the electrode securely in any position. The welding cable attaches to the holder through the hollow insulated handle. The design of the electrode holder permits quick and easy electrode exchange.
How are electrodes used in the welding process?
Welding electrode Welding electrode is a piece of wire or rod, which can be of metal or alloy and has a flux with or without flux and carries an electric current to obtain sufficient heat for welding. At one end it is fastened to a holder and an arc is installed at the other. Electrodes are the most part of welding work.
What do you call a clamping device for electrodes?
Electrode Holder An electrode holder, commonly called a stinger, is a clamping device for holding the electrode securely in any position. The welding cable attaches to the holder through the hollow insulated handle.
Is it possible to weld without an electrode?
Welding without electrodes is impossible in most welding processes, mainly divided into two parts, based on the electrode work function.
