we have a process were the welders hold a welding rod to the bit while welding with oxy-acetylene torch. While doing this the welders hand is within the vicinity of the flame which is being 'bounced' back of the bit and with the welder holding the welding rod in place is heating up his glove and eventually damaging it. The welders all wear welding heat resistant gloves but in this example the welder has gone through 3 gloves on one job and states his hand is very red after a period of time. He has been instructed to change his gloves as often as he needs and to take regular breaks. According to welder they previously tried a welding rod hold fixture but this was not suitable. Anyone got any ideas or suggestions they may have came across before? Goin to annoy some engineers now to see if they can help with a solution too.
Cheers in advance!

Has a risk assesment been done with the conclusion that there is not a safer way of undertaking this task??
If the answer is no then it should be done, if the answer is yes then an alternative type of PPE should be considered.
As an ex welder there are enough products on the market which stop the operative from burning himself.

Thanks for your responses.
More details...oxy-acetylene welding of a bit. Welder holds a welding rod to the bit and applies the torch flame to the bit. The flame slightly bounces back of the surface of the bit and into the direction where the welder is applying the welding rod. The small finger section of the welding glove is in and out the vicinity of the flame during the job and the glove eventually gets burnt. This section of the welders hand gets heated (but not burnt!). They have stated they have previously tried a holding fixture for the welding rod but that it did not allow them to have adequate control for positioning the rods when welding.
The previous risk assessments identifies PPE as a control measure. They currently use BSEN388 Cat 2 Welders glove. I am going to engineers for possible solutions but thought I'd ask if anyone knew of any fixtures, devices or other control measure they may have used in the past?
Cheers

undertake a job safety analysis to confirm just what is happening thereafter you may have to settle for some burnt gloves etc

Don't try to use the last few inches of the rod?

As with MP, why do the welders need to hold the rod so close to the bit? I used to weld, albeit badly, without needing to wear gloves.

You don't say if this is a finishing process or a complete operation.
If this type of welding causes problems, can you change the type of welding process, could Arc welding or Mig etc.
Have had cause to change process with previous employer, Mig welding removed 90% of the risk involved with the process.
Just a thought.

This may be a bit obvious but I can remember being taught (many years ago)the importance of using all of the welding or braising rods. Put a slight kink in one end so you are aware of which one is hot and then use till you are near to flame.
Allow stub end of rod to cool and straighten out the kink. Get new rod put warning kink in one end and then gently weld the stub end on to the other.
Very sad to say that in those days we often did not wear gloves so you took care to keep enough distance between hand and heat source!!
Hope that this helps.
Malcolm
