3 INSTALLATION
Only qualified personnel should perform this installation.
Only personnel that have read and understood this Manual should install and operate this
equipment.
Machine must only be plugged into a receptacle which is grounded in accordance with valid
regulations.
Note
The power switch should be in the OFF position when installing work cable and electrode cable and
when connecting power cord to input power.
Select a suitable location
The UWI 203 TP inverter welder has an IP23S rating. Locate the welder in a dry location where there
is free circulation of clean air into the louvers in the back and out the front of the unit.
Ensure minimum 50cm free space on all sides. If free flow of air is hindered the machine will
overheat.
A location that minimizes the amount of smoke and dirt drawn into the louvers reduces the chance of
dirt accumulation that can block air passages and cause overheating.
Avoid tilting
The machine must be placed on a secure, level surface, maximum 15º out of horizontal.
Assembly
Select polarity to electrode based on recommendations on the electrode package and the job at
hand. For GTAW (TIG) welding negative (-) polarity should always be to the torch.
