8-2. Polarity
There are two welding output terminals,
『＋
＋ ＋
＋』
and
『－
－ －
－』.
Select the polarity according to the operation, referring to the table below.
<Caution>
Follow the instruction of the welding rods, the polarity of which is specified.
8-3. Connection – Welding Cable
Danger: Electric Shock
Always examine welding cables, power cables and plug etc., to ensure there
are no defects present, prior to operation.
Before connecting or disconnecting a welding cable from welding output
terminals, stop the engine, and remove the engine key. A person performing
this task must always keep the key.
①
Stop the engine.
②
Connect the welding cables to the DINZE connectors, a welding rod holder
and a material holder.
<Caution>
Always fit the correct size DINZE connectors.( Recommended parts
：
DIX SK70)
Ensure the welding cables connections are made correctly.
Be sure to connect the cables tightly to welding output terminal. Otherwise,
welding output terminals may burn due to the heat caused by poor connections.
Do not use a cable without the DINZE connectors. Personal injury or damage to
the machine may result as a consequence.
8-4. Duty Cycle
Duty cycle is the percentage of time the load is being applied in a 10 minutes period.
For example, a 50% duty cycle represents 5 minutes of load and 5 minutes of no
load in a 10 minutes period. Be sure to take 5minutes break after each 5minutes of
continuous welding time.
<Caution>
The equipment may become damaged due to overheating, if continuous welding
periods exceed 5minutes or if break period is reduced.
This machine produces drooping characteristics to EN60974-1.
