AC DC welder is two types of arc welding that produce an electric arc using various currents. An electric arc is created between an electrode and the metal being welded in several methods of welding. The heat from the electric arc is used to fuse the metals together.  A power supply, which can be either alternating current or direct current, creates the arc. The power source AC or DC determines the polarity of the electrical current that travels through the electrode. The power source used has an impact on the weld created. The quality and strength of your weld are determined by the electrode polarity you select. The two types of current flow are also known as 'electrode negative' and 'electrode positive,' and are commonly referred to as straight or reverse.  The DC polarity remains constant, whereas the AC polarity alternates between flowing in one direction for half of the time and in the opposite, reverse, direction for the other half of the time. Advantages of DC we...

It is easy to come across various auto-darkening welding helmets in the market that has a plethora of control settings.  But, no matter how technically advanced an auto-darkening welding helmet is, it must have some basic features that make it possible to work with flexibility.  In this blog, we will talk about the three important features that you can look out for in your next auto-darkening welding helmet. 1- Light sensitivity With this control setting, it becomes possible to determine how much light is actually required to initiate the automatic darkening filter or ADF. The more powerful is the light source, the darker the lens on the helmet will get on detection of light.  2- Delay  Delay control denotes the speed at which the automatic darkening filter on your helmet gets activated once the light source is detected by the arc sensors.  It is possible to control the delay setting by slowing it down or speeding it up as per arc initiation and completion to a...
