Have some factors that contribute to the waste of propellant

1)     Poor Gas Coverage Leads to Contamination

To troubleshoot gas contamination issues, first check the gas cylinder label to be sure you’re using the right type of gas for TIG welding, Next, set the proper gas flow rate. In fact, excessive gas flow creates turbulence and swirling currents that pull in unwanted airborne contaminants (and it can cause arc wandering).Third, check all the fittings and hoses for leaks. Any breach may pull air into the shielding gas stream, which can cause the weld to be contaminated (and you’ll waste money if gas escapes). Rub soapy water over the hose and all fittings. If bubbles form, you have a leak and need to replace the defective components.Finally, assuming you have a full cylinder, the right type of gas and no leaks, consider that you may have a tank contaminated with moisture.

2)     Welding Aluminum in the Wrong Polarity/Adjusting Balance

To defeat this, always TIG weld aluminum with the polarity set to alternating current (AC). TIG welding in AC allows the electrode positive (EP) portion of the cycle to blast away the aluminum oxide while the electrode negative (EN) portion melts the base metal. A feature called AC balance control allows operators to tailor the EP to EN ratio. If you notice a brownish oxidation and or flakes that look like black pepper in your weld puddle, increase the cleaning action.

3)     Craters

Fix crater cracking issues by continuing to feed filler rod while slowly reducing current at the end of a weld.

4)     Poor Color on Stainless

Discoloration on a stainless steel weld caused by overheating, which not only affects a material’s color, but degrades its corrosion resistance and mechanical properties as well. Unfortunately, once this error is made, there is nothing that can be done to fix it except for scrapping the part and starting over. To prevent overheating, reduce amperage, slightly increase travel speed or shorten the arc length. If your welding equipment features pulsing capabilities, now is the time to learn how to use them. Pulsing reduces heat input, and it offers excellent control of the weld puddle.

To avoid the problem delay engine during fluid flow thought the pipe

1)     Avoid revving the engine when a delayed engagement occurs. Increased engine speed produces friction and can damage the clutches and bands.

2)     Allow time for the transmission to engage to prevent needless damage.

3)     Check the fluid level. Consult your owner’s manual for correct filling and checking procedure as this varies with different manufacturers.

4)      Some models do not provide a means for you to check the transmission fluid level. In this situation, it is best to contact your local Mister Transmission and seek expert advice.

5)     If you are able to check your fluid level, remember it is very important to use the correct fluid type. Using the wrong transmission fluid can lead to problems with shifting, torque converter clutch application, or ultimately cause transmission failure.

6)     Again, consult your owner’s manual to find the correct transmission fluid type for your vehicle. If it turns out that your fluid level is low, you may have a leak somewhere.
