Can i buy any butane to refill it or has to be a specific can from master appliance?

Yes, you can buy the butane for refill

If the electric ignition fails, can I still ignite it with an external spark or flame?

Hi from Art Clay World USA, Yes, you can use an external spark or flame to ignite the torch. Please remember to follow all safety instructions enclosed with this device.

is this torch powerful enough to heat a stuck bolt and get it loose?

Worked for me! Twice in the past week. I like the small directed flame for heating just the nut. Works 100% better than my propane torch which seems to heat everything in sight and never works to get a nut loose.

About how many refills can i get from the the 5 oz butane canister ?+

We use a 5oz canister of butane for filling our torches. Although we have not keep an accurate count, one of our Teachers said she easily can refill her torch at least ten times. Tom, Art Clay World USA, Inc.
