reverse polarity and straight polarity
The answer is right but a bit of furthur explanation is required. Polarity can be changed in DC output welding sets. The heat of the welding arc is concentrated on the positive terminal. So when thick plates are welded as more concentration of heat is required on the job the job is kept +ve ie. straight polarity is used.
For thin plates concentration of heat is on the filler rod ,so reverse polarity is used.
What else can I help you with?
Can a DC motor be turned into a welder?
A dc is an acronym for direct current & 2 be put in to use,changed to ac which could then be used in welding
What determines weather the polarity of a welding machine is set for dcen or dcep?
DCEP supplies about two-thirds of the heat at the end of the rod, which allows more digging action, or penetration, into the base metal. It's what you want to use for thick steel. For thin steel, direct current electrode negative (DCEN) is best.
How is current controlled in welding transformer?
in welding machine, the transformer used is basically a current transforrmer. so by changing the tap of secondary side of transformer, we can increase or decrease the current in the transformer.
Is your house alternating or direct current?
Alternating current. Direct current is used in batteries.
How welding current is generated?
Welding current is typically generated through a power source that converts electrical energy into a suitable form for welding. This can be done through mechanisms like transformers, rectifiers, or inverters, depending on the type of welding process being used. The current is then delivered to the welding arc, where it generates the heat necessary to melt and join the workpieces.
The old welding machines used electromagnetic winding to step up the current for welding rods. What is the new principle inside the welding machines?
The new principal inside welding machines is based on metal-arc welding, whereas the older welding machines used electromagnetic winding to increase the current in welding rods.
What letters are used to direct current?
DC are the letters for direct current AC are the letters for alternating current
What letters are used to indicate direct current?
DC are the letters for direct current AC are the letters for alternating current
Where do you use direct currect?
An example of direct current is the current used from a car battery to activate the starter motor. Also the flashlight uses direct current.
What type of current is used in battery?
DC direct current
What current types are diodes used in?
Direct Current or DC
What is difference between welding rod and electrode?
welding rod is used without applying current through it while the other one is, current is passing thru it..i.e. Welding rods are used in TIG welding process while Electrodes (E6011, E6013, E7017..etc..) is used in SMAW process
