A little more insight for you......
I know Helen & Graeme personally (the eBay sellers known as ghanglobalimports ) and I can safely say that they are both honest people in life as well as an ebay seller.
Graeme is indeed "in the trade" and does stainless TIG welding for a major company, he and his familly are as local as it gets having been in the area for 3 or 4 generations...... buying from him is not an issue & the 12month warranty he offers is concrete.
I've seen what has come back and its either one of two things
1/ faulty electronic part or failure of the board in general, Graeme carries spare parts to fix the simple breakdowns but replaces the entire unit should the problem be of a bigger issue.
NB: a general board failure is found usually before the unit leaves his place.... as he said to me if it works here then it wont miss a beat once it's delivered
2/ user mistake ..... like the DC inverter welder that was returned after it fell into a horse trough ! ..... & fully replaced under the warranty !
I bought a DC inverter from him less than 6 months ago and have a couple of other items aswell from him too .... still waiting on my new extra long tig torch but
As for the Mig itself..... I've used one of these and as a home handy mans unit they are a good buy & are capable of a good penetration weld on material up to 5mm by a 'learner welder'.
There are however 2 down sides to these units, the first being the exposed wire spool & the 2nd being the increadibly short earth lead.
The wire spool can be covered fairly easily when the unit is stored but in 'work mode' I found that sparks from the grinder managed to contaminate the actual wire being so exposed..... long term storage is also an issue in that the wire will .... I repeat WILL.... become rusty on its surface.
The only real way of fixing the problem is to make a steel cover from some 1.6mm sheet and fix it to the unit thus sheilding the spool and giving a good rotection from both natures and the w/shops enviroments.
The short earth lead is a real pain in the left testicle.... right one too for that matter !!!
The mains power lead is longer
A quick trip to the local autopro shop ( or other automotive store ) and a replacement length to one better suited will fix the problem for around the $70 mark.... ( heavy duty earth lead for a car/truck is as good as you'll need .... dont buy the std earth lead tho, not flexiable enough & generaly wont handle the job well ).
The short leads are common on 99.99999% of the China imported welders, be they mig earth leads, tig earth leads, plasma earth leads, or both the work and earth lead on the DC inverter welders......
As I said at the start, I've got one of Graemes "Firewelder" DC inverter welder..... first and only mod it has had is the dumping of both leads and new long ones fitted in their place...... other than that.....
Cant fault it or ghanglobalimports
