When I retired I gave all my welding shop equipment to my son-n-law(SNL). After 10 years of use with little or no maintenance there are several items of equipment in serious need of a bit of tender loving care(TLC).
SNL has recently acquired an older Snapon model 230sl MIG welder that is not feeding wire nor welding as it should. I think it needs to have the gun polarity reset from electrode negative to electrode positive.
Hobart model 175 MIG welder is not feeding any wire to the gun. Not sure but I suspect the trigger switch has a broken wire or bad contact at the trigger. So I will dissemble the gun and re-solder the trigger wires. If that fails I will check the trigger it’s self and replace the trigger if need.
The 9 inch angle head grinder also has a sticking trigger problem. Most likely it needs to be disassembled, cleaned, lubricated and reassembled.
I’m sure that the larger air compressed has not had water drained from it’s air tank this year so I will also drain the air tank before our first day of freezing weather.
SNL works in town, so I will have him pick-up a small order of 1/4 inch rod and an assortment of 1/8 inch by 1/2, 3/4 and 1 inch wide flat steel and a new bottle of CO2 gas for the MIG welder.
If you only do a small amount of welding using flux core wire is fine but flux core wire cost 2 or even 3 times as much per-pound as solid wire. However CO2 gas is required as a shielding gas when using solid wire.
