There is no such thing as guaranteed ignition. There is only a very large tech pool and very high regen rate. The two weapons that are usually the subject of such comments are the Hellfire and Volcano.

The Volcano is easy to explain - you have a Maliwan sniper with a legendary accessory. In that order, you will also get good pool size, low fire rate and high regen rate. Put them all together and you would have a tech pool that never depletes.

The Hellfire is a bit touchy. The pool size and regen rate are much higher, but being an SMG also means that the fire rate, and consequently the proc chance, may overshadow the regen rate and deplete the pool. Having a Hellfire not proc occasionally just means that the proc rate is only slightly higher than the regen rate. The reasons why this is not so obvious is again because of time. Reload time allows the pool to regen, but not by very much, as I'm assuming reload buffs with maximum SMG proficiency - not a stretch to imagine because of the kills you would be getting with a Hellfire. I'm also assuming that whatever you're shooting at with a Hellfire is going to die pretty quickly; if you have mobs, even better. So you're going to be spending less time firing a Hellfire compared to firing a normal-elemental SMG. And more idle time means more regen time, and more regen time means that the pool never depletes to zero, because you fill it up again before the next encounter.

tl;dr
 * Maliwan has tech pool size and active regen rate.
 * Volcano fires too slow to ever deplete the pool.
 * Hellfire regens too bloody quickly. Continuous firing will eventually deplete the pool, but anything more than negligible reload/idle times will give the pool a chance to regen back to full strength.

Might not be 100% chance, but this is 100% my opinion. Just putting my thoughts somewhere.
