Q - Is this a better deal than ordering the parts individually?
A - Yes, buying the kit is cheaper than buying all the parts individually, plus it comes with a case to hold it all.
Q - How long will this whole kit last?
A - It greatly depends on what work is being done and the frequency of use, though the ratio of parts should be consistent with how quickly they typically wear.
Q - When should I reorder consumables?
A - When your 6th nozzle is enlarged or oval, when the pit depth of hafnium/tungsten is over 1/32 in., when cracks appear in the retaining cap, or when slag starts to build up on the shield.
