If your Thermal Arc Welding System isn't starting, here's what to check: * Ensure the power switch is in the ON position. * Verify the voltage of the power lines. * Look for and repair any breaks in the power lead. * Confirm you're using the correct line voltage. * Check the input power connections against the wiring diagram. * Inspect for open circuits to the power switch or control transformer, repairing any broken wires or loose connections. * Examine the control transformer fuse and replace it if blown, after addressing the cause.
