MIG Welding Parameter Settings and Guidelines

So you have purchased your Pinnacle MIGARC or PrimiMIG Welding Inverter and you are new to MIG Welding? Here is a breif guideline to getting a starting point with your MIG welding machine parameters. So let us start by detailing the basic understanding of what each control manipulates:

What is the Life Expectancy of a Safety Harness?

PPE isn’t like perishable food in your fridge or pantry that has an expiration date. Mandated expiration dates could cause complacency among workers or companies that might cut corners to save time or money or wrongly assume that a newer harness might be “good” for another few years.

What is Flux Core Welding Wire or Gasless Welding Wire?

Flux Cored Arc Welding (FCAW) Self-Shielded. In flux cored arc welding the heat is obtained from an arc between a continuous flux cored wire and the work. The flux provides gas shielding for the arc and a slag covering of the weld deposit. The self-shielded flux-cored arc welding process is...

What is MIG Welding?

In MIG Welding a wire from a reel is fed through a welding torch-passing a contact tip supplying the welding current. The wire melts and is transferred to the pool through the arc that is shielded by a gas. The shielding gas is necessary to prevent oxygen from the air...

What is Scratch-Start, Lift-Arc and HF Ignition in TIG Welding?

What is Scratch-Start TIG Ignition? Scratch start is a very basic and rudimentary process, usually found on low cost inverter welders that have been essentially designed for Stick (MMA) welding.  The TIG tungsten electrode is scratched on the job to initiate the arc, and must be quickly lifted off the...
