Brazing rods? Alternative use?

[SiPMerlin150]

I've just had a brain wave....

People use acetylene torch's to heat stiff/seized bolts to expand and release them.... Now i need to replace a few droplinks on my car, and i have no access or skill to use oxy-fuel safely...

Can i use brazing rods to 'arc heat' up bolts to loosen them ?

Just a thought...

Do you mean the carbon arc rods used in one of those guns which brings them together until an arc flame is created? If so then yes, a friend of mine uses them all the time
to warm stuff up for bending, loosening ect.

Dont forget to disconnect the battery on the car though.

And the alternater, i had the diodes go pop on a corsa i was welding once, thankfully it was having a heart transplant the next day!

Yep! Carbon arc rods, they have black carbon tips on the tip. Thats good to know i can use them rather than gas cylinders

Yep, will remember to disconnect the battery also if i find the ecu, i will disconnect that also.

Any brand of carbon rods recommended?

Can i also cut metal with these too?

Why do you need to heat drop links? There not taper fit usually and the threads almost always turn. I use a ricipro saw, mole grips, alan and torx bits (some have an allen key or torx key hole in end of threads) Most used on slippery suckers is a 115mm angle grinder and slitting discs to remove the nut.

Also any stress related components that show signs of exessive heat will fail an MoT
