Weld Machine

Weld machine engine power source can be obtained from:
- Motor fuel or diesel
- Parent depot

High-voltage electrical energy transferred through several las transformer.
Voltage required by the machine weld usually:
- 110 Volt
- 220 Volt
- 380 Volt

Network between the machines in weld workshop, there is a switch disconnect.

Wel machine that is driven with the motor, suitable for use in the work field or the shop does not have any electricity


Bow weld flame caused by electric current obtained from the weld machine.

Flame occurs when the bow is made a certain distance between the electrode and the work of the cable work.

Machines have two types of weld, namely:
- Weld Machine DC (direct current - direct current weld machine)
- Weld Machine AC (alternating current - weld machine flow back and forth)

Installation of cable secondary, the engine can be arranged weld DC / DCSP to be made or DCRP.
- If the cable is connected electrode negative engine, and the cable connected positive relationship then called straight polarity (DCSP)
- The relationship DCSP, heat relief, a third electrode heating and heating of a two-thirds of work.

Means of working to receive more heat from the electrode.
- If the cable is connected positive electrode machine, and the cable connected so-called negative polarity relationship best (DCRP)

notes:
DCSP = direct current straight polarity
DCRP = revers polarity direct current

- The relationship DCRP, heat relief, two thirds and a third electrode heating heat things work. Means that the electrode receive more heat from the object of
- When used D.C.R.P, is?
This depends on:
- The workplace object
- Position welding
- Electrode materials and wire
- The desired penetration

AC joint on the engine, the cable and electrode cables can be exchanged without affecting the changes that occur in the hot flame bow.

Benefits on the engine D.C among others:
- Stable flame bow
- Can use the electrode plated and not plated
- Can welding plate is thin in relation to DCRP
- Can be used to welding in places narrow and humid

The benefits of AC machines, among others:
- Blazing small bow, so porous the possibility on weld
- Equipment and maintenance is cheaper

Large currents in welding can be arranged with setting tool, with interesting detour handle or pressing, depend on the construction.
