8-2 Polarity
There are two kinds of welding output terminals, 『+』and
zFollow the instruction of the welding rods, the polarity of which is specified.
| Application | Connection |

|
|
Normal Polarity | General Welding, | Plus to the Earth (Material) |
| such as construction | Minus to holder (Rod) |
|
|
|
Reverse Polarity | Thin Plate, Build up | Plus to holder (Rod) |
| Welding, Stainless | Minus to the Earth (Material) |

8-3 Connection – Welding Cable
Danger : Electric Shock
zBefore connecting or disconnecting a welding cable from welding output terminals, stop the engine, and remove the engine key. A person performing should always keep the key.
①Stop the engine.
② Connect a welding cable to a crimping terminal and a welding | WELDING ROD | CRIMPING | |||
| rod holder, and connect the other cable to a crimping terminal | HOLDER | TERMINAL | ||
|
|
| |||
| and a material holder. |
|
