ER70-S2 gives better elongation than ER80-D2. Most chassis builders in open wheel use ER70-S2 allows chassis to deform more as car takes multiple hits from flipping. Some do use ER80 either for certain areas or whole car. Your case either one will work just fine. don't burn up the metal and don't f...

It's only .083" wall Lot's of great stuff here I never thought of... Like the welding on cold tube... My shop never gets below 50 because I leave the heat set there.... Even if the tube is say 40 deg. F would it be worth it the warm the material with a torch slightly first? Or is that not cold ...

Going to weld in a parachute bar in my "street outlaws" Turbo charged CHevelle... Lol Anyone used this E80S-D2 on 4130 ? How does it weld? So far I have read NOT to use 4130 rod unless you are heat treating the part afterward... This is the best info I have found below.. A. Although there ...

My Argon is down to about 200 psi and it seems like when I was welding aluminum last night with the same 20 CFH that it didn't have enough gas.
Do you guys keep turning up the flowmeter or at what point do you go get the bottle filled?

Update! Well I ordered a 220VAC 6" fan that was rated at 240 CFM I ran the pump with no fan (once I unbolted the mechanical fan) (Left hand thread bolt BTW) and most of the noise is from the pump... its still loud...but not bad.. I then installed the 240 CFM electric fan and started running 90 ...

Wow, sorry guys! I had a section of a autobody patch pannel left over from my chevelle, that I was told online was 18 gauge. I measured it with the calipers the other day and it was .035" (before I started practicing with it since it is left over scrap) so that is what I though the thickness of...

Should I pre heat it?
Years ago when I was running beads on 1/4" my instructor would have me heat it to 250 first

I want to try pulsing some Aluminum... the HTP manual for the quick start set up just says to set the AC Hz at 200 Hz.. Anybody have any other sugestions for pulse? 3/32" Tungsten sharpened to a point... On Time..background current... PPS,.. balance,..etc on 1/8" flat bar 6061 lap and fill...

Looks like Everlast buys their cooler from the same manufacture that HTP and Nu-Tec do. LOL

I would buy from HTP though so you get the CK torch with CK superflex hose!

Yes this HTP 221 can save 64 different programs..(and it saves everything, even pre and post gas..I have 2 programs saved so far. Lol ...the rule of 33 and yours!

Check out my post below on welding .065 inch 16 gauge mild steel tube.. The Pulse settings that Brian recommended really helped me... Also remember 18 gauge is half the thickness of 16 gauge you need to use .035 inch or .040 inch filler rod and a 1/16 inch tungsten max....if you don't want to worp i...

OK Brian,

I tried it and those are my new favorite settings for this .065 wall tube...!

Since i am new to dipping the rod .8-1 PPS really helps me stay in time....

Whenever I watch Jody's vids it looks like he just runs the torch straight along and dips the rod.... I came from a old job were everyone used the 'lay wire" technique and would weave the torch back and forth free hand never removing the rod from the puddle... I like the dipping to make my weld...

Turn your Freq up to 200 Hz if you can....

I bet your ground and torch are plugged in backwards thou...

Nope works fine on the coolmate. Emailed the folks at htp and they said it was typical for that model torch and the cooler.[/quote] I remember seeing CK and Weldcraft torches sectioned through the heads and the CK had greater capacity water jacket. Maybe the cooler has a pressure sensor for the alar...

The rule of 33 I'm sure is great if you have a machine that will do high speed pulse ( but many imports don't go over epileptic 10 PPS sadly ) & need to control heat on thin material - I do think slow ( like 1PPS or less ) helps newbies keep pace with the filler & is good so as not to overh...

I was Listening to Corrosion of Conformity on Pandora! Lol

That worked very good! I think the next biggest change is my skills

I will give it a shot. But right now I newbie like me likes to run 1 PPS as it helps me time the dipping of the rod

I have been practicing welding .065" 2" mild steel pipe. I get better results with the pulse on... set at 1 PPS, but I have no idea what to set the P.du ie.. "peak welding time" or % of time I am at max Amps when pulsing I also have no idea how to set the background Amps ie.. I l...

Don't get me wrong here guys, I am VERY glad I bought this welder, it is Thousands less than a comparable blue or red machine.. When I bought my Miller 140 Autoset MIG last year it had "Made in Taiwan" stickers on the flow gauge, the ground clamp, the stinger etc... guess where the interna...

So I have the HTP cooler and 25 foot torch. I am also having intermittent alarms for no reason. I am curious if HTP told you to block that little blue line to raise the flow through the sensor? Sent from my iPad using Tapatalk HD Yes sir that is exactly what they told me to do just pull the small b...

[quote="SmartDave"]So of you who have this cooler as I do, have you had any issues with the flow alarm going off yet coolant is still flowing? The flow alarm would not shut off with my 25 foot torch so I called HTP tech-support and the guy told me how to plug or I just folded over the smal...

So I have had my new HTP 221 Invertig for about a week... My only complaint is the water cooler ...HTP Arctic Chill 5460 has a LOUD mechanical fan... I had to extend my 25' torch the full distance away from the welder just to be able to hear the gas shut off on my torch.. I have been wondering about...

Looks like HTP gets the cooler from these from Nu-Tec....according to this they are the replacement for Bernard coolers... http://weldingdirect.com/ntwaco2ga.html It is nice having the flow alarm...and it works! iIf I step on the hoses and cut the flow it alarms right away LOUD! I did have to call H...
