Would Not Recommend

Used once to connect heavier gauge multistrand wire and it was marginal at best given it can only run 1 minute out of 5. Fast forward a few years and it is completely dead. On investigation, the trigger switch has gone bad. It uses a weird contact geometry that does not apply firm pressure so oxidation (kept in the garage) keeps it from connecting. Worse the switch case melts if you try to unsolder the wires to refurbish things. Avoid.

Works, but you'll need a 3/32" Allen wrench

Would Recommend

The included Allen wrench is the wrong size! Even the documentation says that it should be 3/32" but the included Allen is too large to fit. It's also strange that you're expected to store the Allen wrench in the handle. I first noticed that the provided wrench would not fit the handle - then I noticed it wouldn't fit the tool, either. Fortunately, I already had a 3/32" Allen in my pile of spares.

It's a Weller..If you've used one you know.

Would Recommend

Fabulous product. Works exactly as expected. I've use Weller products since the 1960's. Expected high working quality and that's what I got. The gun is quite a heavier duty step up from the usual pencil irons. This gets used in situations requiring that extra heat, very quickly, and with that heat being quite reasonably well concentrated.
