Larry is overthinking it.
Nah...heat expansion is a fact of life with any wand and mega heat.
Most TMs don't get anywhere near 220+ at the wand .
a 4HT cranked with "normal" cleaning on-off duty cycle can get there
And I will have to respectfully disagree with Larry on the wand. It was a great wand,
It isn't about Greenie ..more the phenomenon of how mediocre tools and juices rise to legendary fame when a wildly popular and charismatic "board star" touts it up....the greenhorn just ain't "all that"
It's "decent" wand
at the price point they start at stock..
the Westpack is an improvement over the tinfoil POS CMP wand (cause it's a little more structurally sound at tube and wand head marriage) , but it's still a cheap wand in same class as the AW29
Respectfully
the streaking could be related to the manifold easily bumped/bent out of adjustment too.
Too high of pressure for the design possibly as well
I've been wondering if I use too much heat. It seems overkill to crank the 4HT all the way up.
I've run a mega heat TM "forever", Jer
Capable of 280+ at the machine .
Typically day in and day out we run well below 220 temp range .(200 is plenty for most "average" jobs)
240
IS "overkill" on most jobs ...but when you need it (like that rathole salvage job you were asking about) it can make a substantial difference .
same for long hose runs in winter..the capacity to make mega heat is an advantage
