Stick welding electrode holders let welding operators control the position of the electrode during stick welding tasks. Also known as stingers, the holders connect to a stick welder that supplies current to the electrode.
How do you hold a stinger?
Instead of grabbing the stinger and just letting the lead hang, give the welding lead one wrap around your forearm then grab the stinger. This way your shoulder is carrying all the load instead of your arm. This allows you to carry the weight easier and also allows your arm and hand to easly manipulate the rod.
What is a good electrode holder?
The Lenco AF-25 electrode holder is recommended for electrodes up to 3/16” and up to a 2/0 gauge cable. This means it can be used on a large rig and on large-scale projects.
How do I choose an electrode holder?
The first step in choosing an electrode is to determine your base metal composition.
Base metal properties
What does the metal look like?
Is the metal magnetic?
What kind of sparks does the metal give off when touched by a grinder?
Does a chisel “bite” into the base metal or bounce off?

What is the best electrode size?
Generally the size of the electrode that should be used depends on the thickness of the part to be welded. For thin metals the electrode is only slightly larger than the metal to be welded. For example if a plate is of 2.0 mm thick the electrode of 2.5 mm should be used.
What amp do you stick weld?
A: A 225- to 300-amp stick machine handles almost anything the average person will encounter, as most stick welding procedures require 200 amps or less. To weld material thicker than 3/8 inch, simply make multiple passes — this is what professionals do, even when welding on 1-inch structural steel.
What are the two types of electrode holders?
There are three types of electrode holders available: the 200A, 400A and 600 A. Range Welding Cable sizes 35mm2, 50mm2 and 70mm2.
Why must the electrode holder be correctly size?
Why must the electrode holder be correctly sized? Electrode holders are designed to be used at the maximum amperage rating or less and too high amperage will cause the holder to overheat and burn up. But if the holder is too large for the amperage range being used, manipulation is hard, and operator fatigue increases.
What factors should be considered when selecting an electrode size?
Electrode size – Electrode size should depend on the electrode type, welding position, joint preparation, base metal thickness, and skill of the welder.
How do you size an electrode?
The size of the grounding electrode conductor is based upon the size of the largest ungrounded service-entrance conductors or ungrounded derived conductors (such as for a separately derived system) or the total equivalent area for parallel conductors (AWG/kcmil).
Do size of electrodes matter?
The dimensions of your electrodes should not effect the open circuit voltage, since this is determined solely by the identity and concentrations of the redox species. Once the cell is running, the dimensions may affect how much the voltage drops off as you draw current, known as “overpotential”.
Does size of electrode affect voltage?
Repeated measure analysis of variance and Newman-Keuls post hoc tests revealed that increasing electrode size significantly decreased voltage but increased current and phase charge magnitudes.
What are the three most common electrode sizes?
Common electrodes used in Stick welding are 6010, 6011, 6013, 7018 and 7024 with the most common diameters ranging from 1/8- to 5/32-in. Each of these electrodes offers all-position welding capabilities (except 7024).
What is the easiest rod to weld with?

What will happen if we use wrong size of electrode?
Bare electrodes or electrodes of the incorrect size can lead to brittle welds. In order to produce ductile welds, be sure to use shielded arc electrodes, avoid using excessive current, and pass over the weld several times.
What should you not do when stick welding?
How many times can electrodes be used?
Manufacturers recommend that adhesive metallic mesh cloth electrodes be used no more than 10 times before they are discarded, however, clinically the electrodes are often used up to 30 times. Another concern is sanitation.
Why do my welds drip?
In gas metal arc welding (GMAW) a common unwanted side effect is the creation of what welders call spatter. These are droplets of molten material that are produced near the welding arc. Spatter happens when welding currents are too high, incorrect polarity or if there is insufficient gas shielding.
Is it better to push or pull a weld?
While pulling might create a deeper penetration, in most situations, pushing creates a flatter weld that covers more surface area. In some instances, this can create a stronger weld than what you might get with the pull technique. As mentioned, pulling allows you to watch your bead as its being produced.
