How Is Portable Welding Different From Classic Welding?

Through heating and then pressing the weld spot on the metal sheet, portable spot welding guns can bond multiple metal sheets together permanently. The term spot The application of a continuous-line electrical current is used to generate the heat necessary to bond the sheets. This technique is often called ‘line welding’ or ‘continuous welding’. The term spot welding refers to the actual welding spot where the heat and pressure applied creates the weld puddle. In most cases, you will have to use a dedicated electrical circuit to get the arc to the correct area.

KVA or “a wattage rating” is the electrical output required to create a bind. Since the strength of the weld will be determined by the amount of current that is applied, it is important to determine the appropriate current requirements before starting the job. Typically, portable welders have a maximum allowable current of 200 amps. There are several advantages when using the higher kVA rating power with a portable unit, such as reduced need for cleanup and less wear and tear on the equipment.

Electrodes are the part of the machine that creates the arc and the part that hold the weld in place. The type of electrode is determined by the type of welding being performed. For example, electrochemical spot welding requires two conductors that are insulated by a thin layer of indium tin oxide. A small hole or channel is present in the center of the electrodes. The hole and channel are sealed to prevent the flow of gas.

There are three types of electrodes in a portable resistance spot welder: consumable, conductive, and flux cored. Each type has its own specific characteristics for proper welding use. There are also different electrode compositions, each having different strengths and compatibility with metal sheets. The weld process uses an arch wire to keep the connection between the weld and the metal sheet in place. This arch wire is attached to a welding machine feed to provide a consistent weld.

The pulse feature in portable spot welder machines provides a smooth, even weld with little heat loss from the heating element. There is no heat variation when welding thinner sheet metal. The pulse feature is also beneficial when welding thicker sheet metal. This feature controls the energy of the arc to ensure uniform heating and cooling of the weld. This feature is typically found in gas-powered arc machines and laser electric welders.
