So I broke out the Syncrowave 250 DX to set up for welding the aluminum drawer for the Lathe/Mill tooling cart build. When I turned on the power the cooling system blew at the feed line and ****** antifreeze from three places.
.
The weld craft WP-20 torch has fixed cooling lines so cutting and re-crimping was not an option. I called around and found an upgrade (CS310-25) for $584. What the heck, thats stupid money. I asked the young man on the other end of the phone if I could get a break since I had an account with Airgas (used to be Pima welding) since 1989, he giggled and stated that was the year he was born and quickly re quoted a more reasonable price of $288. The CS310-25 is 25' long and the torch itself can be changed out with other types of torches such as swivel or flexable style torches.
I also noticed the filler cap gasket disintegrated upon opening the poly tank. I sucked out the old coolant and small gasket pieces and headed to Airgas. He gave me the coolant at $24/gal. which is ten bucks cheaper than anyone else in town. While I was there, he talked me into trying out some non radio active tungsten (E-3). insidently, Miller doesn't offer the gasket alone and sells the entire filler cap
. I think I have new wrinkles on my forehead after this unscheduled expensive repair.
Todays purchase: The short return hose was not included with the new torch
. The young man noticed the wrinkled forehead and gave it to me
.
Back in business holding/cerculating coolant.
Being the cheap Bast%#d I am, I decided to make a new gasket from some 1/8" neoprene rubber I keep on the shelf.
I used a scrap piece of aluminum that had the exact diameter I needed and traced it with a razor blade.
Punched the center out as its a vented cap.
The jury is still out on the new E-3 Tungsten. I ran four open corner test pieces and played with the balance (clean/penetration) adjustment.
The numbers are the setting for each weld. .100" aluminum, filler rod .063" E-3 Tungsten 1/16" and 75 amps.
I normally use 2% Lanthanated Tungsten. Its a good stable all around electrode.
I'm a Knucklehead, It turns out I only had ONE aluminum filler rod. I took a quick glance prior to heading over to Airgas and saw a full sleeve of shiny rod, Turns out it was Stainless filler rod
. Lots of mad faces today, but tomorrows a new day
.
Keep the shiny side up.
