Your results will better match what you'll encounter in the field, and will make those machined coupons for a real-world "I need this job" test that much easier. Steve S.

You get two 1/4 inch coupons and six 1/8th inch coupons in each "kit". They do need to be de-greased if you are using them for TIG, but for MIG and stick, not so much. Being cold rolled steel there is no mill scale to remove. Just wipe them with acetone or alcohol, let them dry and weld away.

First time tig welds

Let the part cool off and try again. Once you get that puddle going, you should be dabbing and advancing at least 1-2 times each second. If you're slower than that, you're dumping too much heat into the part and you'll pay for it. Run beads like that over and over again. Let the coupons cool off

But welding test coupons can be pretty thin and need to be held flat for x-ray testing. The most common thicknesses are usually in the .020" - .063" range but sometimes much thinner.

crisp and soft settings.

If you need to fill up a pool you need more volume and if you want to blast the mud off of your truck you need more pressure. It comes down to figuring out the correct amperage AND voltage to run a certain type of rod. 6010 needs to be run on the higher arc force side hence higher voltage. 7018 runs better on the buttery side hence less voltage.

Primeweld TIG 225x Review/Discussion

The 225 will weld 6010 and 7018 well, but you have to understand these welders are made to do tig welding. Yes they stick weld but they lack the big transformers need for stick welding. Also most people don't need to use 6010 or 7018 as these are for code work. Top. Oscar.

So, take a piece that is, and weld the warpage out of it (by laying beads opposite the warpage to "pull" it back towards flat. You'll need to run hot to put enough heat in the plate to move it, but it is a very, very productive undertaking. When done, grind your beads flat/off then re-use that side for practice padding your beads.

Fcaw-g vs fcaw-s vs smaw

6010 will run just a lil' bit smoother than 6011 on DCEP, and the slag is a little bit easier to chip/wire-wheel off, but 6011 can still be made to work well for a steel project like this, IMO. I like to keep the ripples tighter though. It makes slag clean-up a lot easier to deal with.
