Mr Pops   10 #1 Posted June 16, 2015 Can anyone help ?? i have a cosmo 150 gasless mig welder. its been working fine for the past 6 month, now the wire wont feed,no motor working, just the fan and a clicking noise when the trigger is pulled.  Does anyone know what the problem could be, or where i can get it repaired.  Kind Regards Trev:) Share this post Link to post Share on other sites Share this content via...

Can you put a meter across the terminals in the machine (with it unplugged from the mains of course) and see if you get a continuity reading when you press the switch.

cuttingedge   10 #4 Posted June 16, 2015 Take tension off feed roller then try it to see if motor spins,if not disconnect the gun get a short wire and put one end in each hole on the gun housing if motor spins it maybe broken wire in the gun,you can put a external wire on to keep you going instead of spending x£'s Share this post Link to post Share on other sites Share this content via...
bigsexydoug   10 #5 Posted June 17, 2015 The wire isn't stuck in the tip is it ? Or has the wire got a flat spot at the point it touches the roller ? Pull an inch through and retry Share this post Link to post Share on other sites Share this content via...
