2.6 Connection of Welding Voltage Detecting Line

HW0480311
HW0480311
When you use two or more welders, Connect the each welding output cable of the welder as
close to the position where welding is performed as possible.
Separate the welding output cable A from the welding voltage detecting line B,and separate
the welding output cable B from the welding voltage detecting line A as far as possible.(Dis-
tance between Cable A and cable B is required 100mm or more.)
Don't connect the welding voltage detection line with the route where the welding current flows
Fig. 4 Connection of Welding Voltage Detecting Line and Welding outputcable
when two or more welders are used.
• Be sure to connect the welding voltage detecting line.
If the welding voltage detecting line is not connected, the error "Err702: Voltage Detection
Wire Error" may occur, and welding cannot be performed.
• Only if the length of the welding cable and exclusive-use base metal
cable is 5 m at a maximum respectively, the welding source can be used
with a short-circuiting cap for detecting voltage of output terminal (-) on
the connector "CON 7" at rear face of the welding source. For improving
the welding performance, connect the base metal and connector "CON
7" with the welding voltage detecting line whenever possible.
