· Four major cities announced that they will completely ban diesel vehicles by 2025

According to foreign media reports, even before the explosion of the Volkswagen diesel "emission door" scandal, passenger cars equipped with diesel engines have become unpopular in the United States. But in other places, especially in Europe, consumers have chosen diesel cars in their purchases in recent decades.
However, the public's growing concern about air pollution and the mass outbreak of “emissions gate” scandals are beginning to change. According to the BBC report, the mayors of the four capital cities of Athens, Madrid, Mexico City and Paris reached an agreement at the biennial C40 Mayor Summit in Mexico, which plans to completely ban diesel cars and trucks by 2025. use.
The BBC said that the UK also held a campaign to urge the mayor of London to sign the diesel car ban.
According to reports, in addition to banned diesel cars and trucks entering and leaving, the mayors of Athens, Madrid, Mexico City and Paris also promised to do everything possible to encourage the use of electric vehicles, hydrogen fuel gas vehicles and hybrid vehicles.
According to reports, since diesel combustion emits pollutants such as nitrogen oxides and aerosols into the atmosphere, the mayors decided to ban the use of diesel vehicles due to concerns about air pollution.
It is reported that selective catalytic reduction (also known as urea injection) exhaust gas treatment system can significantly reduce the emission of nitrogen oxides and aerosols. In 2008, the United States issued the second phase of automobile exhaust emission standards (Tier 2/Bin 5). Since then, almost all diesel vehicles in the United States have been equipped with selective catalytic reduction converter systems. However, diesel vehicles in the European market have only recently installed selective catalytic reduction exhaust gas treatment systems in large quantities to comply with the Euro 6B emission standards that came into effect on January 1, 2017.
The ban on diesel vehicles represents a major shift in Europe. Due to the low carbon dioxide emissions of diesel vehicles, European governments have previously advocated the use of diesel vehicles. In addition, the high fuel economy of diesel vehicles can help offset the impact of high fuel prices.
This phenomenon is most pronounced in France. But now, the French capital, Paris, is taking some of the most positive measures to curb the use of diesel vehicles.
In July of this year, Paris announced that it banned cars produced before 1997 from entering the city center on working days. Only after the weekend, these vehicles were allowed to enter, except for historic cars. Paris Mayor Anne Hidalgo has said that he hopes to completely ban diesel vehicles from driving onto the streets of Paris, and considering that by 2020, the ban will cover all cars registered before 2010.
In addition, Paris has issued a temporary ban on the ban on the use of internal combustion engines in certain areas of Paris. It is worth noting that the French capital, Paris, provides a sound public transportation system, public bicycle rental service and Autolib electric car self-service car rental service, which can be used instead of driving to meet the travel needs of the citizens. As other cities have not yet built such infrastructure, it will increase the difficulty of implementing diesel bans in these cities.


Electrode Holders

Features and Benefits:  Selection or amperage ratings to cover a wide variety of applications from light to heavy duty applications.  Light weight for convenient, efficient, fatigue free welding.  Holders designed to fit the welders hand and tight spaces.  Fully insulated, glass tip insulators and upper level, fiber handle and spring protector.  Copper alloy jaws and body for maximum conductivity and sgtrength.  Heavy duty spring for positive bite on electrode.  Easy cable installation with large oval point screw.  Component parts replaceable.

A closed head Electrode Holder allowing the electrode to be fitted either horizontally or vertically. The electrode holder is made of glassfibre-reinforced plastic. All Optimus electrode holders are fully insulated and approved to EN-60974-11.

Electrode  HolderAn  electrode  holder,  commonly  called  a  stinger,  isa clamping device for holding the electrode securely inany position. The welding cable attaches to the holderthrough the hollow insulated handle. The design of theelectrode  holder  permits  quick  and  easy  electrode  ex-change.  Two  general  types  of  electrode  holders  are  inuse: insulated and noninsulated. The noninsulated hold-ers are not recommended because they are subject toaccidental short circuiting if bumped against the work-piece during welding. For safety reasons, try to ensurethe use of only insulated stingers on the jobsite.Electrode  holders  are  made  in  different  sizes,  andmanufacturers  have  their  own  system  of  designation.Each holder is designed for use within a specified rangeof electrode diameters and welding current. You requirea larger holder when welding with a machine having a300-ampere rating than when welding with a 100-am-pere machine. If the holder is too small, it will overheat.
