What to do if the Power first SMART TIG AC/DC-200P Welding System arc is not stable?
- P

What to do if Power first SMART TIG AC/DC-200P Welding System is not easy to start the arc?
- C
  Carol HenryAug 21, 2025
  If it's not easy to start the arc or sticking occurs, check the following: * Ensure the plug is properly connected and tightened. * Inspect the workpiece for oil or dust and clean it. * Verify that MMA welding is selected.

Why is there no current output in Power first SMART TIG AC/DC-200P Welding System?
- A
  Austin TaylorAug 23, 2025
  If there is no current output during welding, the cause may be: 1. The welding cable is not connected to the welding unit’s output, so connect the welding cable. 2. The welding cable is broken, so have the welding cable replaced. 3. The grounding cable is not connected or is loose, so check the ground clamp.

What to do if Power first SMART TIG AC/DC-200P Welding System alarm light is on (Overheat Protection)?
- S
  Scott ThomasAug 26, 2025
  If the alarm light is on for Overheat Protection, it could be due to: * Over welding current. Reduce the welding current output. * Working time is too long. Reduce the duty cycle by taking a break.

What to do if Power first SMART TIG AC/DC-200P Welding System has arc blow?
- A
  Ashley PerryAug 27, 2025
  Arc blow can occur due to several factors: * Airflow disturbance: Use a shelter to block the airflow. * Awkward or defective electrode: Adjust the electrode angle or replace the electrode. * Magnetic effect: Incline the electrode opposite to the magnetic blow, change the ground clamp position, connect the ground clamp to both sides of the workpiece, or use short arc operation.

What to do if Power first SMART TIG AC/DC-200P Welding System welding current cannot be adjusted?
- A

What to do if Power first SMART TIG AC/DC-200P Welding System alarm light is on (Current Protection)?
- T
  Tiffany LeonardSep 1, 2025
  If the alarm light is on for Current Protection, there may be an unusual current in the main circuit. Test and repair the main circuit and drive PCB.

Why is there no gas flow in Power first Welding System (TIG)?
- G
  Gregory KnightSep 3, 2025
  If there is no gas flow in TIG mode, check the following: * Ensure the gas cylinder is open and has sufficient pressure; open or change the gas cylinder if needed. * Check for obstructions in the valve and remove them. * The electromagnetic valve may be damaged; change it if necessary.

What to do if Power first SMART TIG AC/DC-200P Welding System molten pool penetration is not enough (MMA)?
- K
  Kathy BassSep 5, 2025
  If the penetration of the molten pool is not sufficient in MMA mode, it could be because the welding current is adjusted too low or the arc current is inadequate. Increase the welding current and the arc current.

What to do if Power first Welding System gas always flows?
- E
  Erika GibsonSep 7, 2025
  If gas always flows, consider these possibilities: * The gas-test button on the front panel is on, turn off the gas-test button. * Something is obstructing the valve, remove it. * The electromagnetic valve is damaged, change it. * The adjustment knob for pre-gas time on the front panel is damaged, repair or change it.
