3. Positive Output Terminal
Welding current flows from the Power Source via heavy duty Dinse type terminal. It is
essential, however, that the male plug is inserted and turned securely to achieve a sound
electrical connection. A loose or worn connection will cause excessive heat and may cause
damage to the front frame or internal components of the welding unit.
4. Negative Output Terminal
Welding current flows from the Power Source via heavy duty Dinse type terminal. It is
essential, however, that the male plug is inserted and turned securely to achieve a sound
electrical connection. A loose or worn connection will cause excessive heat and may cause
damage to the front frame or internal components of the welding unit.
Loose welding terminal connections can cause overheating and result in the male
plug being fused in the bayonet terminal and /or melting of the housing (case) and
/or internal components of the welding unit.
5. GAS OUTLET
The Gas Outlet is a 5/8 18 UNF right-hand threaded female fitting.
6. WATER OUTLET
The Water Outlet is a 5/8 18 UNF left-hand threaded female fitting.
7. ON/OFF SWITCH
