• Do not use the machine for defrosting frozen pipes�
• When working heights, observe safety procedure for
working heights�
After finishing operations
• Always turn off a gas cylinder valve after completion
of works�
• After the final shut-off, examine a place where weld-
ing works were carried out, do not leave decaying sub-
jects, or the heated particles of metal - they can cause

Machines are intended for creation of one-piece con-
nection of various metals (further in the text "welding of
metals") by their local fusion�
All models of welding inverter (TIG) allow welding
metals with direct current, with non-consumable elec-
trode (of tungsten) in an atmosphere of inert shielding
gases� Using this method, non-alloyed and low-alloyed
steel, stainless steel, copper, nickel, titanium, etc� can
be welded�
It is also possible to perform manual arc welding
(MMA) using consumable electrodes with coating�
