welding problem!!!!

my welder acts as if it doesnt have enough voltage or amperage to lay any kind of decent bead on steal plate when i use it at home so i took it to my welding teacher to troubleshoot the problem...well we plugged it in set it to a round about startign point for 1/4" steal plate and it welded beautifully so i brought it home tonight and im havin the same problem...is there a chance my wall socket doesnt have enough amperage in it? its a brand new miller digital 252. any info would help.

220 or 110? you should run it off its own breaker too.your teach didnt tell you that.my freinds circut box was so small he had to plug in down in the basement and turn off all his lights ,or it would blow a breaker

Sounds like a 220... I would check your breaker and plug/wire going through the wall. If you look in the instructions of your welder it will specify a amperage and all that BS about the plug and breaker

cool thanks guys and yea its 220
