How to spot weld with tig welder
WebCan take some tweaking. No one can tell you exactly what you need. It can also be effected by the settings of your welder(how fast it feeds wire). Too fast with too much tension can cause this. Sometimes if you use a welder for awhile the liner for the mig gun will cause this & will need to be replaced as well.

WebJul 19, 2024 · The only way to spot weld aluminum is to use two to three times the weld current you’d use when welding steel. That’s why it requires a three-phase input spot welder. In addition, the spot welder needs to have a capacitor system. This allows it to “charge” and store the electricity, then it instantly discharges a significant amount of power. WebThe presence of porosity in the weld metal is a visible sign of a bad weld. porosity is the presence of holes created from trapped shielding gas released. NO2, O2, and H2 gas are absorbed from the molten weld pool and become trapped in the weld metal when solidified and create porosity.

WebFor example, welding steel that is 1/8" thick (0.125"), you should start at 125 amps. If this is a corner fillet weld then you would want 125 * 1.3 = 163 amps. If welding stainless steel, you want to take your initial thickness number, multiply it by 0.7, then start from there since welding stainless steel requires less heat.
