摘要： A torch lead extension is provided that comprises a conduit having a distal end and a proximal end. The torch lead extension further comprises a distal connector member disposed at the distal end of the conduit and a proximal connector member disposed at the proximal end of the conduit. The distal connector member is engageable with a torch lead connector member secured to a proximal end of a torch lead. The proximal connector member is engageable with a power supply connector member of a power supply. Generally, the distal connector member and the torch lead connector member comprise a distal quick disconnect, and the proximal connector member and the power supply connector member comprise a proximal quick disconnect. Accordingly, the torch lead extension may be quickly assembled between or disassembled from the torch lead and the power supply.
摘要翻译：提供了一种火炬引线延伸部，其包括具有远端和近端的导管。割枪引线延伸部还包括设置在导管的远端处的远端连接器构件和设置在导管的近端处的近侧连接器构件。远端连接器构件可与固定到割炬引线的近端的割炬引线连接器构件接合。近端连接器构件可与电源的电源连接器构件接合。通常，远侧连接器构件和割枪引线连接器构件包括远端快速断开，并且近端连接器构件和电源连接器构件包括近端快速断开。因此，焊炬引线延伸部可以快速地组装在割炬引线和电源之间或从割炬引线拆卸。

摘要： A dual mode plasma arc torch is provided that preferably comprises a start cartridge disposed between an electrode and a tip. In one form, the start cartridge comprises an initiator that is in electrical contact with the electrode and that is resiliently biased into contact with the tip, such that when the plasma arc torch is in a contact start mode, the initiator is movable against the resilient bias to separate from the tip and establish a pilot arc between the initiator and the tip. Further, when the plasma arc torch is in a high frequency start mode, the start cartridge spaces the tip from the electrode such that a pilot arc is established between the electrode and the tip. In other forms, a contact start torch is provided that is operable under high frequency, and conversely, a high frequency start torch is provided that is operable under low voltage.
摘要翻译：提供了一种双模式等离子弧焊炬，其优选地包括设置在电极和尖端之间的启动盒。在一种形式中，启动盒包括与电极电接触并且被弹性地偏置成与尖端接触的起动器，使得当等离子体电弧焊炬处于接触启动模式时，起动器可抵靠弹性偏压从尖端分离并在引发器和尖端之间建立引导电弧。此外，当等离子弧焊炬处于高频启动模式时，起动盒将电极的尖端与电极隔开，使得在电极和尖端之间建立引导电弧。在其他形式中，提供可在高频下操作的接触启动手电筒，相反地，提供可在低电压下操作的高频启动手电筒。

摘要： An activity entry apparatus for making activity entries onto pre-established time log activity forms is disclosed. The apparatus comprises a time log form overlay sheet of resilient and significantly transparent material having a series of writing instrument guides extending therethrough. The guides define a series of activity change segments having lengths at least great enough to extend from one time log form activity section to a directly adjacent time log form activity section. At least one such activity change segment has a length great enough to extend from and between activity sections on the time log form which are separated furthest from one another. The guides also define time interval segments which extend from the activity change segments. The time interval segments have lengths which are equal to predetermined distances between log form time indicator lines which represent selected intervals of time during the pre-established time period for a given activity on the time log form. The apparatus assists a timekeeper in quickly, easily and accurately logging time on particular pre-established forms.
摘要翻译：公开了一种用于使活动条目进入预先确定的时间日志活动形式的活动输入装置。该装置包括具有延伸穿过其中的一系列书写工具引导件的弹性和显着透明材料的时间记录形式覆盖片。指南定义了一系列具有至少足够大的长度的活动变化段，以从一个时间日志形式活动部分延伸到直接相邻的时间日志表单活动部分。至少一个这样的活动改变段具有足够长的长度，以从时间日志形式上的彼此最远分离的活动部分之间和之间延伸。指南还定义了从活动变化段延伸的时间间隔段。时间间隔段的长度等于记录形式时间指示符行之间的预定距离，其表示在时间日志形式上的给定活动的预先建立的时间段内的选定时间间隔。该设备协助计时员快速，轻松，准确地记录特定预先确定的形式的时间。

摘要： Plasma cutting apparatus (10) for use in cutting a material (M). A torch (12) cuts the material. A control unit (14) controls the cutting operation performed by the torch and includes a control module (16) in which the control unit is housed. At least one power unit (18) supplies power to the cutting torch, the application of this power being controlled by the control unit. Each power unit includes a power module (24) in which the power unit is housed. A cooling unit (54) for cooling the torch is also available. The cooling unit includes a cooling module (56). The control module, power module(s), and coolant module are removably stackable one on top of the other.
