Tig Welder Welding Equipment

CCPD
Connection used for welding with the positive part. In this way the heat is concentrated on the material that you must pay, the effect is exploited thermionic electrode, positive charges that move toward the electrode have lower values of kinetic energy, while the anode, ie the material base, is bombarded by electrons that arrive at very high speeds, resulting in a bath of melting deep and narrow.

CURRENT
Do in relation to the type of material to be welded, TIG can be used in direct current in AC.

CCPI
In this connection, there is a greater concentration of heat to the electrode in this case, the torch is connected to the positive pole. This type of connection is hardly ever used because it threatens to ruin the tungsten electrode. Still used in low levels of current, is very effective for removing oxides from the surfaces that must be welded in practice the positive ions, higher weight, accelerated from the arch, crashing against the base material by grinding the oxides and the welding

A.c.
The alternating current is a combination of the two types of connections mentioned above. The heat is distributed to 50%, between electrode and workpiece. With this type of connection, it uses the thermionic sanding to remove infusible oxides of aluminum and magnesium. The positive ions, heavier than the negative charges, affecting oxides disintegrating.
