Why can not welding machine welding electrode spark?
1 subway did not catch, 2 medicine skin covered electrode. 3 the current of the welder is too small, the internal circuit of the 4 electric welder
The size of the spark is related to the matching of current and voltage. The general matching formula is V=14+0.05A. When the voltage is 4, the electrode selection is reasonable, how do you do the above?. Is that correct? The welder is not in size
Is there a spark, but small or no spark at all?But if a spark is small: 1, welding cable is too long and too small; 2, ground is not good or welding cable connection loose and bad contact phenomenon; inappropriate choice of 3, 4, welding electrode; fault.If there is no spark: 1, welding cable is not connected; 2, welding machine output adjustment is not appropriate; 3, welding machine internal fault;I wonder what brand and model of your welding machine?Chengdu Jiatai letter Technology Co. Ltd, professional sales and maintenance of welding machine.
Cause and treatment of welding rod welding spark:1 、 welding current is too small. According to the type and diameter of the electrode used, the welding current shall be explained with reference to the electrode packing box.2 、 the ground wire is not clamped and the ground contact is bad. Check the cable joint firmness with a special ground clamp.3, the surface of the work has greasy dirt, embroidery scale paint, water and other impurities, affecting the electrode conduction. When striking, striking or striking the arc, the instantaneous resistance is greater. It can produce instant sparks, lift the arc, and then rub out the workpiece with an angle grinder, exposing the metallic luster.
