When welding vertically, it's often beneficial to use a slightly higher current to ensure proper penetration and to help overcome the effects of gravity on the molten weld pool. However, the exact current setting will depend on the material thickness and type, as well as the welding process being used. It's essential to balance the current with travel speed and technique to avoid issues like excessive spatter or burn-through. Always refer to the specific welding guidelines for the materials and processes you're using for optimal results.
What else can I help you with?
When welding in a vertical position the arc length is longer then welding in a flat position?
Actually I usually crowd the puddle when welding vertical up. The longer the arc length the more the arc can wander.
How can you select the current values for welding?
The amount of current (amps) is controlled by the user. It's done with a variable resistor. Another thing to note is whether you are welding constant current or constant voltage. If you are welding constant current, the voltage will vary and a set Amp measure will remain constant. With constant voltage, the current will vary and that's determined by the resistance. Constant voltage should be an easier set up. I'm not 100% sure but most stick welding is constant current, which is why increasing the arc length produces more heat, because more arc length should increase the resistance, which would cause the welding machine to increase voltage to keep the current constant.
welding i want to weld steel bars to my trailer should i use a arch welder or a wire feed welder?
arch welding is a more stable form of welding. it get hotter and creates a stronger bond
Why you used Alternating current in gas tungsten arc welding?
A couple primary reasons. 1 the current reversing itself helps to break up oxides on the surface of the metal. 2 Alternating current produces more heat in the arc which is useful in welding aluminum because heat dissipation is rapid in this metal.
What is the difference between arc welding and resistance welding?
Arc welding uses an electric arc to melt and join metal pieces together, while resistance welding uses heat generated by the resistance to electric current flow between two metal pieces to join them together. Arc welding is more versatile and can be used for various types of metals, while resistance welding is more suited for high-speed production and is commonly used in automotive and appliance manufacturing.
Is welding a semi skilled job?
It can be. Basic welding techniques can get you started in the welding field. Stick welding in the flat position for example. The more experience you get usually translates to more money. Certain processes take more skill such as TIG or plasma welding as well as pipe welding and underwater welding. These are considered highly skilled.
What is a typical open circuit voltage for an arc welding machine?
I read that it can go up to 80 Volts, any more and it becomes a shock hazard to the operator.
What is cs welding?
CS Welding is known as Carbon Steel welding that is more beneficial and easy to use for welding purpose.
How does current flow during welding?
Think of electricity as water in a pipe. The larger the pipe the more water can flow thru. That is current = volume = amperage = amount of heat. Voltage can be compared to pressure in a pipe. That is drive/force. Most welding machines allow you to control the amperage but not the voltage.
What are the advantages of using thorium welding rods compared to other types of welding rods?
Thorium welding rods offer several advantages over other types of welding rods. They provide better arc stability, higher current-carrying capacity, and improved heat resistance. Additionally, thorium rods have a longer lifespan and produce less spatter during welding, resulting in a cleaner and more efficient welding process.
What is arc welding answer?
Arc welding is a type of welding using electricity to heat and fuse metal together. In order to control the process the heat must be controlled by varying the current. MIG (Metal Inert Gas) welding uses an inert cast to protect the weld from the air at extreme temperatures during the welding process.

What are the 5 different types of welding?
There are far more than 5 types or processes of welding. Currently the American Welding Society (AWS) states that there are more than 80 different welding and joining processes. However, some of the common welding processes include shielded metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW), flux cored arc welding (FCAW), and oxyfuel gas welding (OFW).
