What is EXOWELD ?
EXOWELD is the brand name of exothermic materials which are marketed and sold by Lightning Protection International Pty Ltd, Hobart, Australia.
EXOWELD Exothermic welding is a cost effective method of completing a high quality electrical connection. The process is simple to follow and through the use of a high temperature reaction a long lasting, quality electrical bond is created between conductors.
Making an EXOWELD Connection：
Step 1
Clean the conductors to be welded.
Place the cables into position in the mold.

Place the cables into position in the mold.
Step 2
Close the handle clamp to lock the mold.
Place the disk into position in the mold.

Step 3
Place the weld metal into the mold.
Sprinkle the starting powder over the
weld metal and on the lip of the mold.

Step 4
Close the cover and ignite using flint ignitor.
Open the mold after the metal solidifies.
Remove the slag from the mold before
making the next connection.

Advantages
- Does not deteriorate with age since the connections are permanent.
- Does not loosen as the EXOWELD connections create a permanent molecular bond.
- Excellent corrosion resistance.
- Electrical characteristics are higher than typical mechanical connections.
- Does not increase resistance above that of the conductor.
- No external power or heat is required to make connections.
- Quality can be assessed visually.
- Easy and simple to install.
ILSE®weld放热焊接说明:
导线与导线焊接:
- 导线的水平"十"字焊接,通常支线被切开.
- 导线的焊接,也可以是不同尺寸铜绞线或不同材料的线之间的焊接,如实心铜线,镀铜钢绞线.
导线与接地棒焊接:
- 导线与接地极焊接,导线通常为铜绞线,也可以为其它绞线.
- 接地极可为镀铜钢等其它材质.
导线与线鼻或铜排焊接:
- 线鼻与设备或建筑物接地引下线之间的焊接,最理想是用于电厂或变电站接地系统.
- 也可用于铜导线与扁钢的焊接.
铜排与铜排焊接:
- 除特殊说明外,一般是铜排与铜排之间的焊接,也可用于不同尺寸的扁钢与扁钢的焊接.
导线焊在钢表面:
- 铜绞线与扁钢表面或者管道表面的焊接,为确认是否烧坏薄钢板或薄管壁,请务必先行试验.

工具:
| 型号 | 名称 | 说明 |
| T01 | 去氧化钢刷 | 可用于清洁铜表面并去除氧化层，带硬钢丝，主要用于清洁氧化不是很严重的导体 |
| T02 | 模具清洁刷 | 对于清洁垂直打开的模具焊渣效果最好 |
| T03 | 焊渣清洁铲 | TS01（#65以下焊药用）或TS02（#65以下焊药用）对水平打开的模具焊渣效果最好 |
| T04 | 增径铜片 | 包裹在导体，直到导线直径与模具导体开口直径相同 |
| T05 | 高温棉 | 在所有钢筋焊接时均需要 |
| T06 | 清洁刷 | 可清洁任何导体，特别适用于粗糙或脏的导体。该钢刷可旋转并可以更换刷头 |
