I think I may have identified an inexpensive way to elevate the aluminum weld coupons sufficiently to enable clamping the new lower profile brass ground electrode I spoke of above directly to the coupons: Home Depot sells 3/4" x 3/4" aluminum U-channel "plywood trim" in 8' lengths. I plan to...

I examined all the Amazon.ca weld clamp offerings, and realized how important the QUALITY, the SHAPE, SIZE, and the DELIVERY reliability of the ground clamps offered really are! I found that: - The excellent clamp mentioned by Van123D looks REALLY good, except for 2 issues that ultimately...

Wow! Both of those suggested clamps look like a HUGE improvement over the wimpy one that came with the machine! I will examine both advertisements and buy one! Looks like that first one comes from The U.S. so is subject to customs delays, but probably worth the extended wait! Jim G

Yes, I am turning the grounding plug in tightly. And I do have two ideas already about how to improve the grounding on the aluminum weld coupons that are my training workpieces: Idea 1: I think I will start placing the freshly cleaned (s.s. wire brush and then Acetone) workpiece coupon so that...

It IS the grounding! Today, I clamped the weld coupon workpiece to the tabeltop with a c-clamp, AND then also clamped the grounding clamp to the workpiece (top scissor of the grounding clamp) and the bottom of the aluminum tabletop (bottom scissor of the grounding clamp). With this setup, I...

I went out and did a bit more practicing this afternoon, and I did the extra thing of clamping the weld coupon down onto the aluminum diamond plate table. The diamond plate was already installed with its UNembossed surface upward to give a flat surface for grounding, but I thought if the...

I have very dry skin which starts to crack if I handle chemicals like Acetone or Lacquer Thinner at all, so I wear inexpensive disposable clear gloves when I am using any chemical. So far, the gloves have not shown any signs of either falling apart or passing the chemical through to my hands...

Ah, I understand. I am pretty sure I can clamp the workpiece with a small metal screw clamp that should not interfere with my ergonomic setup. I'll try that! Thank-you. Jim G

Yes, it is hard to troubleshoot because the occurrence is "not that often" and is unpredictable. Just happens often enough to be annoying, and to require anywhere from just 1 or 2 re-tries to sometimes needing up to maybe 30 seconds ballpark to resolve. Dusty at Pacific Arc also experiences it...

The blue arc SOMETIMES appears with the no-arc, but other times there is no blue arc. Overall, when there is a no-arc, the blue arc is also not there most of the time. Clamping the workpiece to the edge of the table MIGHT work. My concern there is the overall ergonomics. I have the weld coupon...
