The welder is used when the current bottom can not spark is anything to cause
Low current, no spark, usually there is bad contact, for example: copper and pedestal connection screws loose, resulting in contact surface oxidation resistance, switch contact is not good, etc..
The first is to look at the adjustment of the problem, there is no, and some arc current is small will have an impact, second is slow rise time adjustment is not too long, wit welding machine has one is, you adjust the time is long, just can't afford. This is the most basic you should be familiar with your machine in check the welding line, if not, can only find vendors or manufacturers, generally a lot of things are a single phone warranty convenient and easy, as in other manufacturers to what they can learn to really, if the warranty expired, only power in familiar situations after the examination, if not find professionals.
1, the use of welding machine, the current does not hit the end of the spark because of loose joints, there is poor contact place.2, welding machine is also called current welder or resistance touch welding machine. By using the resistance between the two workpieces' contact surfaces, the contact surfaces of two mutually butted metal can be instantly heated, melted and fused instantaneously through a low voltage and high current.3. Welding is suitable for wide range. The metal material which can be forged in principle can be welded by flash butt welding. For example, low carbon steel, high carbon steel, alloy steel, stainless steel and other non-ferrous metals and alloys can be welded by flash butt welding. Welding section area is large, generally from tens to tens of thousands of mm2 cross sectional area can be welded. Flash butt welding is widely used in welding various kinds of plate, pipe fittings, profile, solid parts, cutting tools and so on. It is widely used and is an economical and efficient welding method.
