• Did you know? The barrel of the Python can be rotated 180º, so you can trigger the gun with your thumb.This will keep your fi ngertips off the pot.
• Be sure to always connect the workpiece to a proper earth ground. Connect the frames of electrically powered machines to a properly grounded disconnect switch, receptacle or other appropriate ground. Always double-check the installation and verify proper grounding.

• When installing a replacement power cable ALWAYS use a conductive sealant on the threads to insure maximum weld current transfer.
• For Orbital GTA Welding, tungsten arc gap settings can vary with application. Most manufacturing cell and benchtop tube welding environments benefi t from the following formula: Arc Gap = 1/2WT + .010” [WT=Wall Thickness]. While tube welding in the fi eld and pipe welding applications generally utilize the following: Arc Gap = Wall Thickness up to .070” MAX.
Summer 2004
• Blow out the conduit every time you change a spool of wire.
• Welders always carry soapstones or a piece of chalk... in order to write the word ‘HOT’ on or around a recently welded piece of metal, that in the case of aluminum, doesn’t always look hot.

For GMA Welding, to measure wire feed speed in the fi eld on equipment without a digital display; reduce pre-purge time to zero and turn off PosaStart, hold trigger to measure out wire for 6 seconds, multiply the measured length of wire by 10 (length x 10 = wire feed speed) to estimate the IPM.
