Tungsten-Arc Inert-Gas Welding (Tig) - Paton StandardMIG-160 User Manual

default. If you change this parameter from 50%, the asymmetry between the current pulse
time and the current "pause" time is entered:
By default
"duty ratio" 50%
The machine will calculate that while maintaining the set pulse difference, the
average welding current will be maintained at the main welding current of 60A (as set),
respectively the heat input to the weld will be at the same 60A, but the stability of the
welding process and the mixing of the weld pool will change. This is a very important
condition for the user to accurately estimate the amount of change in weld pool heat input.
These parameters are set up differently in each situation, according to the
requirements of the welder. To change the value of any function in the current welding
mode, see section 6.1.

4. TUNGSTEN-ARC INERT-GAS WELDING (TIG)

Warning! As a safety gas, pure argon "Ar" is used most often, sometimes helium
"He" or their mixture in different proportions. DO NOT allow combustible gases! Other
gases should only be used in agreement with the manufacturer.
Warning! The argon torch must be of the valve type, with a Ø9mm bayonet
connector. Choose the maximum current of the torch according to your working
requirements.
!
Warning Always use a water-cooled torch with continuous currents of more than
150A!
!
Warning A common mistake is to sharpen the electrode to a "needle", while the
arc can "wag" from side to side. The correct sharpening is a slightly blunted tip, and the
fewer are the "needle butts" that can withstand the set current, the better. Keep in mind
that at high welding currents, a very sharpened electrode is easily melted due to low heat
transfer. Also, the "stripes" from sharpening should be located along the axis of the
electrode.
