The SR122 is a portable spot welder with an electronic timer which enables precision spot welding on low carbon sheet steel ( using the standard 

arms supplied ) up to a thickness of 1+1mm. The unit also features welding pressure adjustment. The SR123 is similar to the SR122 but has additional 

features and capabilities enabling welding on low carbon sheet steel ( using the standard arms supplied ) up to a thickness of 2+2mm. The SR123 is 

microprocessor controlled enabling the following functions to be selected from the control panel. A) Welding time. B) Welding thickness. C) Selection 

of normal or pulse welding modes. Both units are supplied with standard 120mm arms and electrodes.

ensure that you read and understand the safety instructions in section 1.

4.1. 

Connection to mains power supply.

 

Before making any electrical connections check that the voltage of the available power supply is suitable for the spot  

 

 

 

welder model that you have purchased. ( See specification above.)

4.2 

The SR122 & SR123 require a 30amp. supply and are suitable for either single phase or three phase connection.

4.3 

The SR122 requires a 16amp plug and the SR123 requires a 32 amp plug. If connecting to a 30amp supply wire the plug as shown on  

 

page 1. If the unit is to be connected to a 3 phase supply this must be done by a 

qualified electrician

.

4.4 

The mains power supply should be equiped with appropriate fuses or an automatic cut-out switch arrangement.

4.5 

If more than one welding machine is to be installed consult a 

qualified electrician

 regarding a suitable 3 phase supply.

4.6 

Before proceeding to set up and use the welder, ensure that the electrical connections have been made correctly.
