I had a similar problem a year or so ago when rebuilding an old
HP double oven frequency standard, where the heater element was
probably nichrome, and which needed to be bonded to ptfe tinned
copper wire. Thought the pulse arc welders very good, but as you
imply, too expensive for a one of job. Eventually used a power
supply to charge a large electrolytic and a tungsten probe in
series with an iron cored choke to generate an arc on break. A
few tries at various voltage levels got the job done as per a
proper pulse arc welder...
