Welding Variables: Talking Voltage and Amperage There are so many welding variables that influence a weld’s quality; the variables are amps, volts, travel speed, filler metal, shielding gas, base material, etc. But have you ever stopped to think about how they...

Over-welding: Almost Everybody Does it to No Benefit Countless times throughout my career I have heard people say “I know the print calls for a 3/16” fillet, but I know it is not enough.” As a result, the welds end up being a 5/16” fillet. And while there are times...

Eliminate High Resistance Areas Poor arc quality can be caused by a high resistance. This produces a “hot spot” due to undersized welding cables or even correctly sized cables that have cuts or splices. When you have a poor arc, double check that the weld cables are...

Simple Solutions Oftentimes, little, painfully annoying welding problems are caused by commonly overlooked culprits. Throughout my career, I have observed frustrated welders that are achieving substandard welds. Many of the substandard welds are believed to be a...

Arc-on-Time, Speed & Consistency Welding automation can be categorized as 1) hard automation or 2) robotic (sometimes called “flexible”) automation. Hard automation is the simpler and least expensive of the two to implement. It lends itself to gantry, track and...

Material Costs are Relatively Small The price of welding supplies is by no means irrelevant; but, in mild steel fabrication, material costs represent only 10-20% of total fabrication costs. For this reason, General Air has invested in multiple Welding Engineers and...
