| AC Welding Machine |
Electrical machinery and classified AC welding machine DC welding machine, welding machine AC is usually a welding transformer, welding machines sedangkam DC transformer apart or equipped with a rectifier diode (Changer alternating current into direct current) motor drive typically uses either diesel or petrol motors and electric motors. AC welding machine that uses a transformer or welding transformer.
Currently widely used welding machines DC because DC has
several advantages of the AC welding machines, such as stable arc, polarity can be set.
Las DCSP (Direct Current Straight Polarity) or Las Straight Polarity.
If the base material or materials to be welded is connected to the positive pole (+) and elektrodenya connected with the negative pole (-) in the way of a DC welding machine is called straight polarity welding or DCSP.
In this way the electric arc moves from the electrode to the base material so that the collision of electrons in the material base that resulted in 2 / 3 heat in the base material and the third heat in the electrode. This will result in melting of basic material more than elektrodenya so that the results have deep penetration welding, so that both are used in welding a slow and narrow weld bead and for a thick plate. Las DCRP (Direct Current Reversed Polarity) or Las Polarity behind. With the welding process in this way the basic material connected with the negative pole (-) and elektrodenya connected with the positive pole (+) of DC welding machine, and DCRP so-called electric arc moving from basic materials to the electrode and the collision of electrons in the electrode resulting in 2 / 3 heat at the electrode and the third heat in the base material.
This will produce more so that the melting electrode welds have shallow penetration, and both are used in welding of thin plates with a width of weld bead.
Welding Las AC (alternating current) or Las Las alternating electric current alternating current there is no positive and negative poles (two both the same) and therefore the inverted penyambungannya behind the results remain the same. Each pole will receive 50% heat, resulting in more normal penetration.
