First of all - apologies for no photos - i'll definitely get some next time!
Second - I know this is the forum for technique rather than equipment but i'm not sure which is the problem!
My first effort at welding this weekend (just starting to build a kit car!) and it didn't go well.
The welder is my father-in-laws Sealey MightyMig XT120 - which I think is a very old model - and hasn't been used in years. I had some 0.6mm wire in it - and a throwaway bottle of CO2 from machine mart. I was trying to weld straight welds onto 3mm sheet and then some 1mm sheet.
Available settings are MAX/MIN and 1/2 - which I think goes from 35a (Min/1) up to 110a (Max/2).
The only other control is wire speed.
It seemed to keep tripping out on a regular basis (loud 'clunk' and it wouldn't feed wire or arc). When I did get an arc the welds just came out like ball bearings whatever settings I used!!! Some of them stuck to the metal - but plenty of them just fell straight off!!
Penetration into the 3mm was very poor - on the 1mm I could at least see a 'burn' mark starting to come through...
Any ideas (or will pics really help)
