WARNINGS
（Concerning Hot Spot II U & Repair）
The Hot Spot II is a pul high energy welding unit and can generate voltages and hot particles that are dangerous to the operator. Care should be taken to avoid coming into direct contact with the uninsulated portions of the holding pliers or wire being welded while using this tool. Particular steps should be taken to avoid damage caud by sparks and sprays of molten metal produced by welding operations. The operator can be protected by a plastic shield from the hot particles. In no ca should the unit be ud without suitable eye protection such as the shaded goggles provided with the welder. Avoid flammable clothing and do not operate in areas containing inflammable or explosive materials. Very high currents are produced by this device so care should be exercid using the unit in any electrical environments nsitive to such puls.
Internal power supply and energy storage capacitors will retain significant charge for an extended time interval after the unit is turned off. Circuit board inspection or repair should be performed by qualified personnel and only after the capacitors have been discharged. The ground electrode of the welder (heavy lug) is electrically common with power line safety ground and the metal ca of the welder. Take care to avoid accidental discharge to the unit's ca or other grounded conductors.

All potential operators should be aware of the above cautions and the welder's operating characteristics before using the Hot Spot II.
警告
（HotSpot II的使用和维修）
HotSpot II是脉冲高能焊接单元，它能产生电压和热飞溅颗粒物，这些对操作者是有危险的。在使用该设备时要格外小心，拿钳子时不要接触非绝缘的部分或被焊接的线，并且要采取特别措施来防止在焊接操作时熔融金属火花溅到身上。操作人员可以使用塑料防护物来保护自己，使自己免受热颗粒造成的伤害。操作人员绝对不能在不戴合适的防护镜的情况下进行操作（焊接机已配护目镜）。不要穿易燃的衣服，不要在有易燃或易爆材料的地方操作。该设备能产生强电流，应该小心不要在对脉冲比较敏感的地方使用该设备。
内部电源和储能电容器能在设备断电后延长操作时间。线路板检测或维修都应由专业人员操作，而且在电容器完全放完电后进行。焊接机的接地电极（插头上的粗接线柱）是电学通用的与电源安全接地线和焊接机的金属盒连接的电极。设备对外壳或其它接地导体的意外放电要格外小心。

Controls, Indicators, and Overload Protection
queenie什么意思The Hot Spot II is powered from the AC line through a step-down transformer and rectifier. Front panel indicators and controls allow the operator to easily monitor the state of the unit, determine the level of energy to be transferred to the storage capacitors, and initiate a weld cycle, the maximum power output of the Hot Spot II is approximately 250 Joules. The power level is t by the position of the front panel control knob. The power ranges, normal (low) and turbo (high), are lected by a two position toggle switch. Initiation of the welding discharge is controlled by a snap action push button switch.
The range switch and power level control t the voltage to which the energy storage capacitors are charged. Peak voltage on the low range is approximately 35 VDC and on the high range 75 VDC. The stored energy is proportional to the square of the capacitor voltage. Increasing the tting of the control knob will cau the capacitor to be charged to a higher level. However, decreasing the tting will not immediately reduce the value already stored so a welding cycle will always relea an energy pul equal to the highest power tting since last recent discharge.
When the internal capacitors are being charged to the level t by the energy control potentiometer, the charging indicator glows brightly. The PI and P2 indicators show that the two high energy storage capacitors have been charged. Once the energy in the storage capacitors has been raid to the val
ue indicated by the control potentiometer, the charging indicator will be only dimly lit or off. After a weld cycle has discharged the capacitors, the charging cycle will be repeated automatically (following a short delay to assure internal SCR turn -off) A ret table circuit breaker in the primary AC line is accessible on the unit's back panel and protects against damage from internal circuit shorts and similar fault conditions.
调控、指示和超负荷保护
Hot Spot II是通过降压变压器和整流器来给焊接机提供交流电的。面板指示和控制便于操作人员对设备状态进行监控，从而决定电容转换储存的能量级别和启动的焊接周期。Hot Spot II的最大输出功率大约为250焦耳。能级是由面板控制按钮的调整决定的。能级范围----正常（低位置）和涡轮（高位置）是通过双位拨动开关来选择的。启动焊接放电是由便捷按钮开关来控制的。
能级范围开关和能级控制旋钮可以设定能量储存电容器的充电电压。低位置时的峰值电压大约为35VDC，高位置时的峰值电压为75VDC。能量储存大小与电容器电压的平方成正比。调高控制按钮的数值将会使电容器的充电值增加。但是，减少设定值不会立即减少已经储存的电压值，因此每一个焊接循环释放的能量值与上次循环放电时最高的能量值相等。
当内部电容器充电至能量控制旋钮的设定值时，充电指示灯将会变亮。P1和P2指示灯会显示两个能量
储存电容器的充电最大值。一旦储存电容器的能量升高至控制旋钮的设定值时，充电指示灯会变暗或熄灭。在一个焊接循环电容器放电后，充电循环将会自动重复进行（紧跟着会有一个延缓来保证内部SCR关闭）。主交流电路上可重置的断路开关已接到设备后部面板上，用来防止因内部线路短路或小的错误操作引起的损坏。
Hot Spot II Capabilities and Features
The principal difference between the Hot Spot II and the Standard Hot Spot is its heavier wire welding capacity. The Hot Spot II can handle wire pairs as heavy as #14 gauge. It can also clo larger tubes than the standard unit and can do light duty stud welding as an aid in wire harness attachment and in insulation blanket installation.
For the same weld power the Hot Spot II can operate at lower arc voltage than Standard Hot Spots. This produces less weld splatter and somewhat aesthetically superior thermocouple beads. There is no difference in the reading accuracy of the junctions produced by either unit.
The Hot Spot II operates only from AC power. A battery powered version of the unit is not offered. Its less than 14# weight and compact design make it a very portable package. Simplified front panel controls and status display facilitate operator training and understanding.

Identical procedures are ud when making and attaching thermocouples as were developed for the Standard Hot Spot. Expectedly, there are fewer problems with T type junctions or heavier wire sizes, the same internal power circuitry operates for both high and low energy ranges. Therefore, control resolution desired and maximum energy required should dictate which range is to be employed for a particular application.

Hot Spot II功能和特性
Hot Spot II与标准的Hot Spot的主要区别是它的粗丝焊接能力。Hot Spot II可以焊接#14（1.6mm）粗的线。它也可以将大尺寸的管子封口，可以连接轻型螺柱和铠装线，以及协助安装隔热衬垫。
使用同样的焊接能量，HotSpot II可以在比HotSpot的电弧电压低的情况下操作，这种焊接产生的飞溅物少，而且产生的热电偶焊结球也要美观些。任何一款设备在结球时，读取焊接能量的精确性上并没有什么差别。
Hot Spot II只能使用交流电源，我们不提供电池供电的设备。其重量只有14磅（6.3公斤），而且设计紧凑、便携。简化的面板控制和状态显示便于操作培训和学习。
制作和焊接热电偶的程序设计与HotSpot焊接时的程序相同。该设计也达到了预期的效果，在焊接T 型
热电偶或粗丝时出现的问题较少，同样的内部能量电路可以在高和低两个量程下操作。因此，所需的控制能力和所需的最大能量要求应该指出特定设置的特殊要求。
HOTSPOT II 产品使用说明书
tadCaution!
The Hot Spot II can be damaged if operated in a mode which allows the charging circuit to operate continuously. The welder is designed to recharge to maximum power in less than 10 conds.navigator
• Starting a CHARGING CYCLE while still in a DISCHARGE MODE will allow the charging circuit to Latch On in a continuous discharge cycle. This extends the end of the normally short charging cycle and will OVERHEAT and DESTROY the charging circuit FET switch and associate components.
• TO A VOID CHARGING CIRCUIT DAMAGE, OPEN the PLIERS CIRCUIT after each discharge. During welding operations, the Red LED charging lamp should be on for NOT MORE than 10 SECONDS. Care should be taken that unusual welding modes, modification to the circuitry, or discharge during a charging cycle do not create the above damaging conditions.

如果在充电模式下进行持续操作的话，Hot Spot II有可能损坏。该焊接机在10秒钟内能达到充满状态。
• 在放电模式下起动充电循环（就是放电后，电极还在接通中），会使充电电路锁定在连续放电循环中。这种情况下会延长正常的短时间充电模式，会导致设备过热和损坏充电电路的FET开关和相关组件。
• 为了避免充电电路损坏，在每次放电完毕后拿开钳子，断开电路。在焊接作业时，充电红色LED指示灯显示的时间不能超过10秒。应该注意的是，不要非正常焊接、不要修改电路和在充电周期内不要放电，这样就不会产生上述的损坏。
