What to do if my Soyer BMH-22i stud does not weld with total flange surface?
- R
  Richard GibsonAug 21, 2025
  If the stud isn't welding with its total flange surface on your Soyer Welding System, resulting in deficient weld joint strength, consider the following: * Time too short: Readjust the time for main current duration according to the table. * Poor earth connection: Check earth cables and earth clamps for a tight fit, and tighten if necessary. * Soiled workpiece surface: Clean the workpiece surface. * Deformed stud face: Use new welding studs. * Incorrect stud projection: Set the distance between the stud holder and stud face to 2-3 mm. * Welding gun tilted: Ensure that all three gun legs are simultaneously and evenly positioned on the workpiece. * Lift incorrectly set: Set the lift correctly.

- A
  Alexander FloresAug 25, 2025
  Intensive sparking and a nearly molten stud flange on your Soyer Welding System can be caused by: * Time too long: Readjust the time for main current duration according to the table. * Welding current too high: Readjust the welding current.

What causes my Soyer BMH-22i Welding System stud welder to switch off?
- M
  Manuel LeeAug 26, 2025
  Your Soyer stud welder might switch off due to several reasons: * Incorrect stud lift setting: Set the stud lift according to the welding gun's operating instructions and switch the stud welder back on. * Gun removal during welding: Avoid removing the welding gun while the main current is flowing and switch the stud welder on again. * High gas pressure: Adjust the gas pressure to the prescribed value. * Poorly conductive workpiece surface: Grind the surface area. * Defective mains supply: Check the fuses of the mains supply.

What to do if there is no shielding gas flow during welding process of Soyer Welding System?
- M
  Margaret MorenoAug 28, 2025
  If there's no shielding gas flow during the welding process with your Soyer Welding System: * Check gas cylinder connection: Ensure the gas cylinder is properly connected, and the valve or shut-off valve is open. * Adjust gas flow duration: Set the gas flow duration to the desired preflow time; avoid setting it to '0'. * Regulate gas flow rate: Set the gas flow rate to 4-5 l/min using the control cock.

What to do if my Soyer BMH-22i Welding System stud lifts, but main current is not ignited?
- D
  Deborah BaileySep 1, 2025
  If the stud lifts and preweld current starts, but the main current doesn't ignite on your Soyer Welding System: * Ensure the operating mode is set to 'OP', not 'PRE'. * Clean or grind the workpiece surface. * Adjust the lift according to the welding gun or welding head's operating instructions, ensuring it's not too high. * Set the gas pressure to the prescribed value, ensuring it's not too high.

What does it mean if LED 'Stud welder not operative' lights up on Soyer BMH-22i Welding System?
- N
  nicholasknightSep 3, 2025
  If the LED 'Stud welder not operative' lights up on your Soyer Welding System, it could mean: * There isn't enough free space around the stud welder, leading to heat accumulation. Make space available to eliminate heat accumulation. * There's an excessive welding sequence. Please observe the admissible welding sequence.

What does it mean if LED 'Lift test carried out too long' lights up on Soyer BMH-22i Welding System?
- E
  Emma AndersonSep 6, 2025
  If the LED 'Lift test carried out too long' lights up on your Soyer Welding System, it means you've activated the lifting magnet for too long or too often when testing the lift. Wait until the coil in the welding gun has cooled down.

What causes single-fillet bulging at equal points in Soyer BMH-22i Welding System?
- D
  Dr. Wesley SpencerSep 8, 2025
  Single-fillet bulging at equal points in your Soyer Welding System is caused by a magnetic blow effect, where the arc is forced into a certain direction. To resolve this, alter the fixture of earth clamps, place iron parts on the edges, and/or rotate the welding gun.

Why my Soyer BMH-22i stud thread scorched?
- J
  Jessica BennettSep 10, 2025
  If the stud thread is scorched on your Soyer Welding System, it's likely due to a worn stud holder. Replace the stud holder.

What to do if there is no arc even though Soyer BMH-22i Welding System is ready for operation?
- J
  juliemaddenSep 12, 2025
  If there is no arc even though your Soyer Welding System is ready for operation, the stud might be too loose in the stud holder. Press the stud holder together or tighten it.
