Welder polarity has to do with DC (Direct Current) welders. Essentially, polarity is the direction of the current. Straight polarity means that the current is running from the electrode, to the metal, and back through the grounding clamp. Reverse polarity means that the current is going the opposite way, from the grounding clamp, through the metal, and up through the electrode.

How much does a welder weigh?
The weight of a welder can vary depending on the type and size of the equipment being used. A portable welder typically weighs between 10-50 pounds, while larger industrial welders can weigh several hundred pounds.
Why must a welder's duty cycle never be exceeded?
Exceeding a welder's duty cycle can lead to overheating of the welding machine, which can cause damage to the equipment and reduce its lifespan. It can also result in poor weld quality and increase the risk of accidents or injuries to the welder. It is important to follow the duty cycle recommendations to ensure safe and effective welding operations.
What is meant by a welder and duty cycle?
A welder is a person who joins metal parts together using heat and pressure. Duty cycle refers to the percentage of time within a specific period that a welding machine can operate at full capacity without overheating.
How do welder's glasses work?
Welder's glasses work by using special lenses that have a very high optical density to shield the eyes from the intense light generated during welding. These lenses are designed to filter out harmful ultraviolet and infrared radiation while allowing a safe amount of visible light to pass through. This protects the welder's eyes from damage and allows them to see clearly while working.
What protection should be worn at the welder is working in the area that exceeds to set limits for noise?
The welder should wear hearing protection such as earplugs or earmuffs that are designed to reduce noise levels. It is important to choose the appropriate level of protection based on the noise levels present in the work environment. Additionally, using a combination of earplugs and earmuffs can provide extra protection.
What are the application of straight polarity arc welding?
AC (Alternating Current) and DC (Direct Current) is used to describe the polarity of the electric current that the welder generates and in what direction it travels. If you use the wrong polarity for a certain welding rod, your weld strength will not be very good. The general terms associated with polarity are reverse polarity and straight polarity. These are common to the welding trade. Another way to describe the two terms are electrode positive and electrode negative. Electrode positive is the same as reverse polarity. Electrode negative is the same as straight polarity. Hence the + and the - written on your welder where the cables connect to it. Any type of welding rod you buy will be labeled as to what polarity should be used for welding with it. Using the correct polarity will ensure the proper penetration and the over all look of the final bead. If you use the wrong polarity you can tell by the signs. There will be an excessive amount of spatter, you will have bad penetration, and you will have less control of your arc. Some welding machines have a switch to adjust the polarity. If your welder doesn't have one you will need to switch the welding cables around where they plug into the machine. If you want reverse polarity, you need to make sure the electrode holder is plugged into the + terminal. The easiest way to tell if you are using the wrong polarity is by the sound and the feel of the weld you are laying down. If you don't have much experience with stick welding you will have a little more trouble determining the difference. I have seen guys weld all day long with the wrong polarity. Then I would grab their welder to use for couple of minutes and I could tell right away. It all comes down to experience.

Can make mig welder use flux core if doesnt have plus - change polarity?
Don't know exactly what you are asking. Most MIG welders can be used for flux cored, or bare wire. Polarity doesn't change, same for both. incorrect bare wire with gas and flux cored run different polarity i think what hes asking is how do you change polarity if there is no switch and the answer is usually on most welders in the wire spool compartment there are 2 lugs one with a ground wire and the other with a jumper wire to the wire feeds drive roll assembly. to switch the polariy just reverse the connections on the lugs.

What does the term single hand welder mean?
A "single hand welder" is any person welding on a job that is not using their own personal equipment. I.E., welding with a company welder or rented welder until you can afford to buy your own welder.

The wire feed welder is a MIG welder.
