TECH TIP: Your Aluminum Welds Are Telling You Something PT. 2 - Travel Speed
Tuesday, June 12, 2018
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.
TECH TIP: NEW PART 101 - Weld-On Ground Clamp
Tuesday, June 5, 2018
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 Thickness.
- For the PR-2 or PR-3: You will set the Weld Time and Weld Power.
- Loosen the threaded knob surrounding the stud. This will expose the tip that will be welded to the panel. Place the tip of the stud on a clean metal surface in the desired location. A benefit of the new style helps you get the ground welded closer to the weld area versus on an adjacent panel, keeping the repair area as small as possible.
- Touch the electrode from weld gun to another clean metal surface on the same panel or next to the ground without touching the ground itself.
- Depending on gun style of the equipment being used, either press the trigger to initiate the ground clamp weld (Manual Gun) or touch to the surface until the weld automatically occurs (Auto Gun).
- Once the ground tip is welded, tighten the threaded knob down snug to the surface, this will add rigidity and secure the ground to the panel.
- Now you're ready to weld!

TECH TIP: Programming The Crater Fill Function For Welding Aluminium On SP Series MIG Welders
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 REQUIRE "CYCLE" TO BE ON "FULL"
