WARNING! Use welding head shield to protect eyes and avoid exposing skin to ultraviolet rays given off by electric arc. Wear safety welding gauntlets.
If difficult welds are to be performed and the welding parameters are unknown, it is advisable to carry out several trial runs on test pieces in order to
p
determine the right welding current and gas flow.

ARC WELDING PROCEDURE
Please note that the way the welding cables are connected to the inverter for ordinary ARC welding may be different to the way the cables are
connected for standard TIG welding. Whilst most stick electrodes are connected to the positive terminal certain types need to be connected to the
negative terminal. It is therefore essential that the user refers to the electrode manufacturers instructions to ensure that the correct polarity is
selected.
Before commencing welding read the safety instructions in Section 1.
