Why can DC welding machine weld any electrode?
Direct current, especially the direct current produced by the inverter DC welding machine, is relative to the power frequency AC welding machine. The arc is stable, the spatter is very small, and the arc is not easy to break. The welding parameters have almost no fluctuation under the influence of input voltage. Three phase welding machine also supports thrust current, hot arc ignition function. It can avoid sticking electrode when arc welding with basic electrode. If there is no frequency exchange of AC, it is difficult to weld slag hole. A metal with a high sensitivity to carbon is not susceptible to cracks in heat sensitive metals.Basic electrode J426 J506 can be AC DC welder dual-use. These two kinds of welding rod contain arc stabilizer. However, from the quality of welding, DC welding machine is much better quality than AC welder.
AC DC stability is not available
General welding rod (acid welding electrode) is both AC and DC dual-use.Basic electrode, recommended DC, AC is also ok.Cellulose electrodes must be dc.So it comes to this conclusion.
