我们把包含前面已说的焊接控制的基本程序在内的、出厂时设定的各种基本机能及性能的如下变
化、扩展，称之为可护机能。
延长电缆的连接
将延长电缆接到焊接电源正端的输出端子和送丝装置输出端的电缆之间，可扩大焊接作业的活动
范围。(此时，您也必然将准备的母材端的电缆延长，较大的焊接物等特殊情况除外)
另一方面。因连接的延长电缆的电阻及电缆的连接方式，会产生电压降等不利于焊接作业的因素。
连接电缆越长，截面积越小，不利影响越大。
因此，延长电缆选用不当，可能会引起焊接不良。
在选用延长电缆时，请注意以下几点
●延长长度与电缆截面积的关系

●延长电缆越短越理想，请注意不要接过长的电缆，这毫无必要。
●延长电缆请务必拉直使用。
(焊接时延长电缆卷曲会引起电弧不稳)。
●在使用延长电缆时，请使用FTT(无)装置。 (参见P20、P35)
All functions can be extended
We have said before that contains the control of the welding procedures, basic, factory set of basic function and performance of the following change
, Extended care functions can be called.
Extension cables linking
Extension cables are received welding power-output terminal and sent to the output device wire cable between welding operations can be expanded activities
Scope. (At this point, you must also be prepared baseplate side of the extension of cable, welding etc. larger except for special circumstances)
On the other hand. The extension cables for connecting the resistance and cable connections, would have voltage drop and not conducive to welding operations factors.
The longer the cable, smaller cross-sectional area, the greater negative impact.
Therefore, the improper selection of extension cables, which may lead to bad welding.
In selecting extension cables, please note the following points
