Welding machine power source can be obtained from:
- gasoline or diesel motor
- subtation
High voltage electric power is transferred through several kebengkel weldingtransformer.
Voltage required by the welding machine is usually:
Voltage required by the welding machine is usually:
- 110 Volt
- 220 Volt
- 380 Volt
- 220 Volt
- 380 Volt
Between networks with a welding machine in the garage, there is a breaker switch.
Welding machines driven by motors, suitable for field work or in the garage that has noelectricity network.

Arc welding flame caused by electric current from a welding machine.
Arc flash occurs when made certain distance between the electrodes with the workpiece and the wires clipped to kebenda work.
Welding machine there are two kinds, namely:
- welding machine DC (direct current - direct current welding machine)
- welding machine AC (alternating current - welding machine alternating current)
Secondary cabling, the DC welding machine can be configured / made into a DCSPor DCRP.
- if the cable is connected kekutub negative electrode machine, and the cable is connected positive kekutub then called straight polarity relationships (DCSP)
- the relationship DCSP, the heat that arises, one third and two thirds of heatingelectrodes heats the workpiece.

- the relationship DCSP, the heat that arises, one third and two thirds of heatingelectrodes heats the workpiece.
Means workpiece receives more heat from the electrode.
- if the cable is connected kekutub positive electrode machine, and the cable is connected kekutub negative polarity it is called the relationship the best (DCRP)
- if the cable is connected kekutub positive electrode machine, and the cable is connected kekutub negative polarity it is called the relationship the best (DCRP)
notes:
DCSP = direct current straight polarity
DCRP = direct current polarity revers
- the relationship DCRP, the heat that arises, two-thirds of the heating electrodes and a third heating workpiece. Mean electrode receives more heat from the workpiece
- when used D.C.R.P, it?
This depends on:
- workpiece material
- position welding
- materials and electrode salutan
- the desired penetration
In AC welding machines, cables and wiring the electrodes can be interchanged without affecting the heat changes that occur in the arc flame.
The advantages of machine D.C among others:
- stable arc flame
- can use the electrode covered and not covered

The advantages of machine D.C among others:
- stable arc flame
- can use the electrode covered and not covered
- to weld thin plates in relation DCRP
- can be used to weld in damp places and narrow
The advantages of AC machines, among others:
- arc small flame, so minimize the possibility of porous timbunya on ridge-ridge las
- equipment and maintenance is cheaper
Large current in the welding can be arranged with a tool setter, with a detour handlepull or push, depending on its construction.
Large amperage produced machines can be viewed on the scale amperes
- can be used to weld in damp places and narrow
