Pro Spot Welding

Get To Know The Pro Spot Gas Regulator For MIG Welding: Shielding Gas  plays a vital role in welding. It ensures proper clean welds and keeps them porosity free. Proper set up and correct shielding gas are a must for quality welding results. Facts: Many gas regulators in the field are measured in Pounds per Square Inch (PSI), or most commonly Cubic Feet per Hour (CFH). The Pro Spot regulator, however, is measured in  LITERS PER MINUTE (L/min). This can cause confusion regarding what the proper setting should be for steel, aluminum and silicon bronze. It is very important to make sure the settings are correct to achieve the desired welding results. Recommended settings on the Pro Spot supplied regulator (82-7001): NOTE: The regulator needle should never be maxed out or in the red (above 15LPM) for any of the MIG welding processes.  ALUMINUM: 4-10 L/min  The thinner the aluminum, the lower the gas setting. This helps with splatter and weld height inconsiste

When weld results are not as desired, we often blame our welding equipment.  More often than not, this can be an easy fix by adjusting the pace at which you weld. See below how travel speed can make a difference in your weld results. 

You will notice an exciting new style Weld-On Ground Clamp shipping out replacing  the prior  grip-style Ground Clamp and the Magnetic Ground.  The NEW Weld-On Ground Clamp (SA-0157)  makes attaching your ground faster and easier. Previously if you had a dent in the middle of a door, you would have to ground metal and clamp  the ground to the door edge creating two areas to paint/blend.  Now you can weld the ground next  to the dent  so that you don't have to paint or blend additional panels, keeping the repair area as  small  as possible.  The Weld-On Ground Clamp (SA-0157) is compatible with the following products:  PR-3 PR-2 SPOT WELDERS Single Sided Function (i5, i4s, i4, PR-2000, PHS-101) How to Use: The Weld Settings depend on the material thickness and welder being used.  The goal is to leave the smallest heat footprint possible in order to save the corrosion protection on the back side.  For Spot Welders: You will set the Material Thickn

Programming The Crater Fill Function For Welding Aluminium On SP Series MIG Welders  In order to keep up with growing demand for Aluminum repair in today’s collision repair industry, it is important to understand the differences between welding Aluminum and Steel panels.  One of the noticeable differences between them is the crater that forms when the Aluminium weld bead is completed. This is due to the heat created at the end of the weld puddle and can cause a weak spot.  There are a couple techniques we can use to avoid craters at the end of the weld:  As soon as the weld bead is stopped, pause for a second letting the weld cool, then re-strike the arc to fill in the crater.  Speed up at the end of the weld, then move back onto weld to fill in crater. Program the  Crater Fill Function on the SP welder. This is the best way to achieve optimum results.    NOTE: SP-1, SP-2, SP-5, REQUIRE TRIGGER TO BE IN 4T MODE, THE SP-5.3, AND THE SP-5 DP DO NOT REQUIRE 4T MODE BUT DO REQU
