What is a Dual Purpose Wire Feed Welder?

A dual purpose wire feed welder is a type of welder that can use both flux-cored and solid wire for welding. Flux-cored wire is a type of wire that has a flux material inside it that creates a shielding gas when heated. This gas protects the weld from contamination and produces a smooth and strong weld. Solid wire is a type of wire that does not have any flux material inside it. It requires an external shielding gas, such as carbon dioxide or argon, to protect the weld from contamination and produce a clean and neat weld.

A dual purpose wire feed welder allows you to switch between flux-cored and solid wire welding depending on your needs and preferences. You can use flux-cored wire for outdoor welding or when you need more penetration and strength. You can use solid wire for indoor welding or when you need more precision and appearance. A dual purpose wire feed welder also allows you to adjust the voltage and wire speed settings to suit different materials and thicknesses.

What is Resistance Welding?

Resistance welding is a general term for a group of welding processes that use an electric current to generate heat and melt the metal at the weld area. Resistance welding does not require any filler material or shielding gas, making it a cost-effective and efficient method of joining metals. Resistance welding works by applying pressure and electric current to the metal pieces that are to be joined. The electric current flows through the metal pieces and encounters resistance at the point where they touch. This resistance generates heat, which melts the metal and forms a weld nugget. The pressure is maintained until the nugget solidifies and creates a strong bond between the metal pieces.

Resistance welding has several advantages over other welding methods, such as:

It is fast and easy to perform.
It produces consistent and high-quality welds.
It does not affect the appearance or shape of the metal pieces.
It can join dissimilar metals or metals with different thicknesses.

Resistance welding also has some disadvantages, such as:

It requires specialized equipment and skilled operators.
It can cause distortion or damage to the metal pieces if the current or pressure is not controlled properly.
It can create weak spots or cracks in the weld if the metal pieces are not clean or aligned properly.
It can be affected by the electrical conductivity and resistance of the metal pieces.

There are many types of resistance welding processes, each with its own applications and characteristics. Some of the most common types are spot welding, seam welding, projection welding, and butt welding. These types differ mainly by the shape and size of the electrodes that are used to apply pressure and current to the metal pieces.

What are Electrodes for Resistance Welding?

Electrodes for resistance welding are the parts that deliver the pressure and the electric current to the metal pieces that are to be joined. They are usually made of conductive and refractory materials that can withstand high temperatures and pressures. The shape and size of the electrodes depend on the type and thickness of the metal pieces and the desired weld shape and size.

Electrodes for resistance welding can be classified into two main types: solid electrodes and back-cast electrodes (also known as insert electrodes). Solid electrodes are made of a single material, such as copper, copper alloys, tungsten, molybdenum, or tungsten heavy metal alloy. Back-cast electrodes are made of two materials: a copper or copper alloy shaft and a tungsten, molybdenum, or tungsten alloy insert. The insert is the part that contacts the metal pieces and creates the weld, while the shaft is the part that connects to the welding machine and conducts the current.

The choice of electrode material depends on the electrical conductivity and resistance of the metal pieces. For example, conductive electrodes, such as copper or copper alloys, are used to weld resistive materials, such as stainless steel or nickel. Resistive electrodes, such as tungsten or molybdenum, are used to weld conductive materials, such as copper or gold. The electrode material should also have a high melting point, high hardness, high strength, and good wear resistance.

Electrodes for resistance welding wear out over time due to heat, pressure, and spatter. They should be cleaned and dressed regularly to maintain their shape and performance. They should also be replaced when they are damaged or worn out. The quality and consistency of the electrodes affect the quality and consistency of the welds.

How to Use the Century 85 Amp Dual Purpose Wire Feed Welder?

The Century 85 Amp Dual Purpose Wire Feed Welder is a user-friendly and versatile device that can help you with various welding projects. To use the welder, you need to follow some basic steps, such as:

Install the welder according to the instructions in the manual. Make sure you have a proper power source, a gas cylinder and regulator (for solid wire welding), a ground clamp, a welding gun, a wire spool, and a drive roller that matches the wire size.
Select the polarity of the welder according to the type of wire you are using. For flux-cored wire, use DC negative polarity. For solid wire, use DC positive polarity. To change the polarity, you need to switch the polarity jumper inside the welder.
Set the voltage and wire speed controls according to the material thickness and type of wire you are using. You can use the chart inside the welder as a guide, or adjust them by trial and error until you get a smooth and stable arc.
Prepare the metal pieces that you want to weld. Clean them from any dirt, rust, paint, or oil. Clamp them securely to prevent movement or gaps. Make sure they are well grounded.
Put on your safety equipment, such as gloves, helmet, and protective clothing. Make sure there is adequate ventilation in your work area.
Squeeze the trigger of the welding gun and start welding along the joint. Keep a steady speed and distance between the gun tip and the metal pieces. Release the trigger when you finish welding.
Inspect your weld for any defects or flaws. If necessary, clean it with a wire brush or a chipping hammer.

The Century 85 Amp Dual Purpose Wire Feed Welder also has a spot/stitch function that allows you to perform spot and stitch welding for precise and fast results. To use this function, you need to set the spot/stitch switch to either spot or stitch mode. In spot mode, the welder will create a single spot weld when you squeeze and release the trigger. In stitch mode, the welder will create a series of spot welds when you hold down the trigger and move along the joint.
