Question about Miller Electric Manufacturing Electric Syncrowave 250 DX TIG 907194032 Welder
Assuming that you are familiar with Tig welding anyhow, and are using Argon gas and have made sure that your fittings are snug on both ends of hose (don't forget there is a fitting at the rear of you torch accessible by gripping and sliding handle back), and that your ceramic nozzle is also snug let's get you welding aluminum. First off never weld aluminum (or anything else really once you try them) with collets and collet bodies provided with torch, replace those with Gas Lenses and Nozzles and a gas lense insulator. You can get away with green or red tungsten, with a gas nozzle you can now turn your flow down to 20-25. As with previous post, CLEAN is #1 use clean stainless steel brush with WOOD handle not plastic, I choose to stay away from chemical cleaners. Now with a ball on your tungsten make sure you make a cleanup/heatup pass of area you are welding til there is no black stuff (contaminants) before adding any filler rod. Go ahead make a pool, add filler at your hearts content....WOW like night and day!

TIG weding is next to brain surgery as far as CLEAN goes.
You must get your AL clean, either by 1. Clean with a NEW Stainless Steel brush or 2. by using a chemical from the welding house that is made just for that.
Your cup must be clean and your gas flowing at the right amount,no leaks in o-rings or hoses.
Hold your cup more vertical and keep your filler rod in the gas shield always,no in and out movement.
In short you must get everything perfect to get quality Heliarc Al welds.
Good luck, HowardRoark
