Safety Guide for Thermic Lance's Operation

Thermic Lance Safety Guide
Daiwa Lance manufactures Thermic Lance (TL) as one of our high-performance products, and having knowledge to actually use Thermic Lance properly is a challenge. The users have concerns about safety due to the high heat generated by Thermic Lance, also find an optimal proposal from the manufacturers of furnace pipes with the aim of improving the production cost efficiency.

Based on our previous experiences, we can provide clarity on the compatibility of existing equipment with the appropriate size of Thermic Lance by introducing to customers the appropriate size based on actual testing. 
In this blog, we are going to introduce the safety guide for Thermic Lance Operation and some advice to operate with safety guide.

Prepare Safety Tools and Operating Equipment

One of the initial tips to using Thermic Lance with effectiveness is to prepare all necessary safety equipment to protect the operator during processing time. Also, the position of the operator is somehow closed to the area of cutting scraps in a scrap yard. Therefore, preparation is definitely a crucial step for highly effective protection.

When safety tools are all set, the operators will check the Oxygen Sources with precise Oxygen Flow and Pressure Levels as the second step for safety. The adjustment will be controlled by Oxygen Regulator and Oxygen Hose as well. This step will help the operator before sticking the Thermic Lance to the whole system.

Adjust Ignition and Handling Position

The most crucial part of the 3 tips is the way of carefully setting up the Holder, connecting the Thermic Lance, and standing correct position to operate.


Step 1: Set up the Holder



Step 2: Connect Thermic Lance to Holder



Step 3: Connect the Oxygen pipe to the Holder


Use acetylene torch to heat one end to red hot, then start blowing oxygen

Step 4: Use an acetylene torch to heat one end to red hot, then start blowing oxygen



Step 5: Keep safety distance and Keep Thermic Lance at around 60 degrees angle



Step 6:  Connect to the next piece of Thermic Lance in terms of continuing cutting


You can see the types of connections of Thermic Lance in the upcoming part in case you keep continuing Step 6.

3. Use quick coupling

Easy connection type. You just hit Thermic Lance and couple together to the wall or floor a coup of times then connected. Most popular size for this quick coupling type is ¼”(OD 13.8mm) x Length TYPE-T.

Recommecdation of using Thermic Lance

After burning and using Thermic Lance, the tube will shorten closer to the Holder. Keeping a moderate distance is very crucial to keep safety for the operator. For oxygen pressure from 8 to 10 bars, the remaining length of Daiwa Thermic Lance recommended is leaving about 1 meter to achieve safety.

Depending on the gas pressure adjustment, size of TL, type (Type T or Type W), and the intended use of the Thermic Lance, we recommend that you should contact our technical department directly for various advice, for the safest and most effective usage.


Due to the great heat produced by Thermic Lance, users are concerned about their safety. In order to reduce production costs, furnace pipe makers develop an ideal solution for consumers. We can introduce to customers the suitable size based on actual testing and, based on our prior experiences, provide clarification on the compatibility of existing equipment with the proper size of Thermic Lance.
