Indicating Light（Power, Thermal Protection）
There are two indicating lights : power indicator and thermal indicator. When the
machine is turned on, the power indicator will be on to show it. When the thermal
indictor is on, it shows the machine is overloaded working and the internal
temperature is too high. The machine will turn off automatically but the fan will
still be working. When the internal temperature is decreased, the machine will
turn on automatically.
Current Adjustment
Current adjustment is on the front panel of machine. It is an infinite current output
adjustment
Output "+"Connector
This is the connector for welding cable most often when STICK welding. When
this machine is used for TIG welding, this connector is for the grounding cable.
Ground Cable and Clamp
The ground cable and clamp is attached to the work piece to complete the flow of
current needed to weld.
