Will 120 volt equipment work on a 110 volt transformer?
Yes.
What difference's between potential transformer and voltage transformer?
Both are same. This is an instrument transformer used for metering & protections.
What is the name of the transformer that reduces the voltage?
a step down transformer is used to lower the voltage from the powerlines into your home. a common slang term for this type of transformer is a pole pig.
Can I use a 120 v 24 v 75 VA transformer instead of a 120 v 24 v 40 VA transformer?
Yes that would work. It's all about the ratio. As long as the rated voltage is not exceeded, as there will be a limit to what the insulation can stand, before breaking down. Lower voltages than rated will be safe.
What is the cost of welding machine in india?
Its depend upon the type of welding machine. It varies from Rs50.000 to more than Rs 1,00,000 There are various manufacturers in India like Artech welders, Roteckweld, Pro Arc Welding etc. who offers welding machines at affordable price.
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.
What causes saturation in a welding transformer?
what causes saturation in welding machine
What type of welding machine does not have positive and negative terminal?
Transformer type welding machine
How does welding transform work?
The welding transformer - converts 'standard' mains electricity to high-amp power. The negative lead is attached to the piece of work, and the positive to the welding 'gun'. Touching the welding electrode (from the gun) - completes an electrical circuit - making an 'arc' with enough power to melt the metals together.
What type of welding machine does not have positive and negative terminal connection?
Transformer type welding machine
What is a welding transformer?
A welding transformer is an electrical transformer used in welding power supply. It pulls relatively low current drawn from the mains power (typically limited to 15 A to avoid tripping the circuit breaker) and converts it to the typical 50 A to 500 A used in arc welding and higher currents used in spot welding. The main difference between a Normal Step Down Transformer & a Welding transformer , is Not only to Step Down ( lower ) the outlet supply voltage and at the same time increase the Available Output Circuit Current, but to be also able withstand the Short Circuit Conditions on the Welding Output Side and especially for the Magnetic ( Iron Lamination Core ) Part of the Transformer. This Magnetic Path difference prevents the Supply side Electrical Circuit from Oveloading , espcially during the Striking of the Arc, when the Welding Electrode & the Welding Job touch to initiate an Arc, after which the Welding Electrode is lifted slightly by Experience, to maintain the required weld flow. A Normal Transformer of equivalent rating will not be able witstand this operation without burning out.

Why is a transformer rectifier often prefferred for smaw?
SMAW stands for shielded metal arc welding. The rectifier used in the welding machines must be referring to this type welding.
Why is a welding machine not adjusted when a welder is welding?
two reasons i can think of: 1 - Probably dont need to, usually welding material of constant thickness. 2 - The transformer is mechanically adjusted on most welders, this means that that there would be a possibility for electricity jumping in the transformer, and premature failure, or fire.
What type of oil is used for cooling arc welding machine coil?
which oil use for arc welding machine
What is the difference between rectifier and inverter type welding machine?
A welding rectifier is a m/c which converts A.C. supply to D.C.supply. Rectifiers are used for heavy welding work. An invertor is a welding m/c which converts A.C. supply to D.C.supply and then again converts D.C. to A.C. The wt. of invertor welding m/c is less than a welding transformer.
How many 16 Amps per phase welding outlet can you install to a 30 KvA rating transformer?
..the questions does not say wether the 30kVA transformer is 3 phase transformer or single phase transformer..but it is implying that a single phase welding load at 16A per phase is to be connect to it, it is assumed then that the transformer is 3 phase transformer..we assume load is rated 240V.. ..though not much details is given about the transformer voltage specs. but if is rated 3 phase 415/240V, the approx full load current per phase is given by 30KVAx1.3912=41.736A.. ..but if the transformer was rated single phase 240V say, the approx full load current FLC=30000/240V gives 125ampers.. ..if you further devide the FLC by the intended load current.. ..Recommended no of welders per for a 3 phase 415V transformer and assuming single welding sets =41.736/16=2.6..so you can connect max two welding sets to this transformer per phase,..max 6 weld sets can connect at an approx load factor of 76%.. ..for the single phase transformer, FLC/16=125/16, gives 7.8 but is also recommended not to connect more than 6 welding sets to such transformer for the same reasons..
