WARNINGS

（Concerning Hot Spot II Use & Repair）

The Hot Spot II is a pulse 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 caused 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 case should the
unit be used 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 exercised using the unit in
any electrical environments sensitive to such pulses.

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 these capacitors have been discharged. The ground electrode of
the welder (heavy lug) is electrically common with power line safety
ground and the metal case of the welder. Take care to avoid accidental
discharge to the unit's case or other grounded conductors.

Use the Hot Spot II in well ventilated areas and minimize breathing the
toxic compounds generated by the high temperature arc from the various
elements of the components being welded.

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。

在通风良好的地方使用 Hot Spot II 来减少由

焊接各种零部件时产生的高温电弧附带的有毒气
体。

所有准备操作的人员在使用 Hot Spot II 之前

应该看一下以上警告和焊接机的特性。

Controls, Indicators, and Overload Protection

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 set by the position of the front panel control knob. The
power ranges, normal (low) and turbo (high), are selected 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 set 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 setting
of the control knob will cause the capacitor to be charged to a higher level.
However, decreasing the setting will not immediately reduce the value
already stored so a welding cycle will always release an energy pulse equal
to the highest power setting since last recent discharge.

When the internal capacitors are being charged to the level set 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 raised to
the value indicated by the control potentiometer, the charging indicator will
be only dimly lit or off. After a weld cycle has discharged these capacitors,
the charging cycle will be repeated automatically (following a short delay
to assure internal SCR turn -off) A reset 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 close 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 used 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。
