Inverter MIG---Worth upgrading to ?

Looking at upgrading to an inverter MIG, had a Clarke 160 for over ten years and it's been well used and
up till now a great welder. But recently it's started misbehaving so looking to upgrade.
Tempted by the R-Tech 160 Inverter MIG as I'm very impressed with the AC/DC TIG I bought from them
three years ago. Don't need the 250a one as I'd use arc for anything over 5mm.

Now I have zero experience of inverter MIGs so am after some feed back before taking the plunge.

Hi there,

I'm in a similar position myself. I found some useful advise on the mig-welding forum here.

I also have the same R-Tech TIG machine and am looking for a new MIG.

After much research I'm going to go for a transformer based MIG as I don't need the extra features an inverter one offers, as most seem to be multiprocess (which the TIG already does).

Oxford / Portamig / TecArc MIG machines get a good write up.

Having said all that, if you need the machine to be portable forget transformer ones

Afraid I don't know the answer to your question, but I have an inverter DC tig/arc welder and have often wondered if it would be possible to rig up a spool-on-gun head with a suitable PSU and gas valve and use that with the tig giving the welding power? As I understand it migs need a DC power source too. Would mean there was less equipment to store too!

something like this:

Actually - question answered! SIM.MBE%26ao%3D2%26asc%3D49130%26meid%3D444418ffb8f94f28b246104ca0a71677%26pid%3D100005%26rk%3D4%26rkt%3D6%26sd%3D382277756711&_trksid=p2047675.c1 00005.m1851

ETA obviously both the links are for cheap kit, but you can buy better quality units.

Simple answer Yes, for me night and day to a transformer MIG

I looked at all the options inc the ones mentioned and bought a CWS 160iCWS 160i

I did a write up on it on the MIG welding forum here />
Whatever you buy I think it is worth the extra for local (UK) support and stock.

Still really happy with it. at the end of the thread I show a pic of someone's "first fillet weld" - that was done by my 10yr old daughter!

Yes well worth the change for me as well.

As with any tools buy the best you can afford.

Yes, the Rtech 160 is a good machine. Have had mine for a couple of years and find the arc very stable when using it as a MIG welder , have only tried it once on arc , again very stable arc , the weld wasn't too good but that was down to me .

I upgraded to an R-tech I-Mig-250 2 years ago. Its amazing thoroughly recommended.

Just a word of warning. If an inverter Mig goes wrong its much more difficult to trouble shoot/repair than a transformer type. Now i know R-rech are assembled in china (AFAIK), but the UK backup makes it a wise choice IMO.
