Page 4: Technical Data
2 TECHNICAL DATA Type of welding machine Three-phase static transformer rectifier frequency converter, DC output. Processes MMA (Stick electrode / SMAW) TIG (GTAW) Safety Marking Suitable for use in areas with increased electric shock hazard X: Duty cycle Duty Cycle is percentage of 10 minutes that unit can weld at rated load without overheating. It refers to a 40°C environmental temperature. - Page 5 = Welding current. Range 10 – 320A = No-load voltage Is the voltage between welding terminals (touchable voltage) when the machine is idle and equipped with a voltage reduction function for operator safety. Low value means high operator safety, and with this in mind this machine satisfies the world’s strictest regulation: AS 1674.2-2007 Safety in welding and allied processes (Australian standard) which allows for maximum 35V.

Page 6: Installation
Select a suitable location The UWI 320 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. -
Page 7: Front And Back Panel
4 FRONT AND BACK PANEL Description 1. Active VRD signal. When lit this shows that the Voltage Reducing Device is active, reducing the voltage across the welding sockets. This will happen within 2 seconds after the welding arc is broken to protect the welder from electric chock. Full arc striking voltage will automatically be re-established when the welding circuit is re- established by touching the electrode to the work-piece 2. -

5 WELDING MMA (SMAW stick electrode) welding 1 Electrode Select MMA welding (selector switch up). 2 Workpiece Connect ground (return) cable with good contact to 3 Arc the work piece. Select polarity and amperage as recommended for the electrode and start arc as follows: Drag electrode across work piece like striking a Match and lift electrode slightly after touching work. - Page 9 6 PARALLEL CONNECTION Two pcs UWI-320TP may be parallel connected and will then supply up to 640A current for stick electrode welding and, more important, for Air Carbon Arc gouging. This is done as follows: Set both machines to MMA welding (selector switch up). Set both machines to remote control and if extensions are necessary use same length remote control cables from each machine to the work site where the remote control parallel connection kit, product number...

Page 17: Safety Instructions
12 SAFETY INSTRUCTIONS Arc Welding Hazards The safety information given below is only a summary of the more complete safety information found in the Safety Standards listed in Section 1-5. Read and follow all Safety Standards. Only qualified persons should install, operate, maintain, and repair this unit. During operation, keep everybody, especially children, away. - Page 18 FUMES AND GASES can be hazardous. Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health. Keep your head out of the fumes. Do not breathe the fumes. If inside, ventilate the area and/or use exhaust at the arc to remove welding fumes and gases. If ventilation is poor, use an approved air-supplied respirator.
- Page 19 HOT PARTS can cause severe burns. Do not touch hot parts bare handed. Allow cooling period before working on gun or torch. MAGNETIC FIELDS can affect pacemakers. Pacemaker wearers keep away. Wearers should consult their doctor before going near arc welding, gouging, or spot welding operations.
- Page 20 MOVING PARTS can cause injury. Keep away from moving parts such as fans. Keep all doors, panels, covers, and guards closed and securely in place. H.F. RADIATION can cause interference. High-frequency (H.F.) can interfere with radio navigation, safety services, computers, and communications equipment.
