8-2 Polarity
There are two kinds of welding output terminals,
『+』
and
『‑』.
Select the polarity according to the operation, referring to the table below.
<Caution>
z
Follow the instruction of the welding rods, the polarity of which is specified.
8-3 Connection – Welding Cable
Danger : Electric Shock
z
Before 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.
①
Stop the engine.
②
Connect a welding cable to a crimping terminal and a welding
rod holder, and connect the other cable to a crimping terminal
and a material holder.
③
Connect the welding cables to the output terminals.
In terms of DGW311DM, connect cables to the welding output
terminals, referring to the table below.
