Why is my Thermadyne Welding System electrode melting when the arc is struck?
The electrode might be melting because it's connected to the ‘+’ terminal instead of the ‘?’ terminal. Also, the WAVE BALANCE might be greater than 50%. Try connecting the electrode to the correct terminal (‘?’) or reducing the WAVE BALANCE to below 50%, or increase the electrode size.
What to do if the Thermadyne Thermal Arc 185TSW Welding System weld bead is too wide and flat?
If your weld bead is too wide and flat, or you notice undercut at the edges, or excessive burn through, it could be due to the welding current being too high. Try decreasing the welding current.
How to fix excessive bead build-up with Thermadyne Welding System?
Excessive bead build-up, poor penetration, or poor fusion at the edges of the weld can occur if the welding current is too low. To resolve this, increase the weld current and ensure proper joint preparation.
What to do if Thermadyne Thermal Arc 185TSW weld bead is too wide?
If the weld bead is too wide, there's excessive bead build-up, or excessive penetration in a butt joint, it may be caused by travel speed being too slow. Increase the travel speed to correct this.
How to correct uneven leg length in Thermadyne Thermal Arc 185TSW Welding System fillet joint?
Uneven leg length in a fillet joint is often caused by incorrect filler rod placement. Re-position the filler rod to achieve even leg length.
