2. Isi ihe na nlezianya anya maka MIG ịgbado ọkụ nke igwe anaghị agba nchara
1. Jiri a larịị àgwà ịgbado ọkụ isi iyi, na-eji agbara polarity maka DC (ịgbado ọkụ waya jikọọ na nti electrode)
2. N'ozuzu, a na-eji argon dị ọcha (99.99% ịdị ọcha) ma ọ bụ Ar + 2% O2, na ọnụ ọgụgụ na-agba ọsọ bụ ọkachamma 20 ~ 25L / min.
3. Ogologo Arc. MIG ịgbado ọkụ nke igwe anaghị agba nchara na-adịkarị welded n'okpuru ịgba mgbanwe ọnọdụ, na voltaji e kwesịrị imezi ka ihe arc ogologo nke 4 ruo 6 mm.

3. Isi ihe na kpachara anya maka igwe anaghị agba nchara flux cored waya ịgbado ọkụ
1. Jiri ewepụghị àgwà ịgbado ọkụ isi iyi, na-eji reverse polarity n'oge DC ịgbado ọkụ. Ị nwere ike iji eriri ikuku CO2 nkịtị ka ọ weld, mana biko mee ka nrụgide dị na wiil ndepụta waya dị ntakịrị.
2. The na-echebe gas bụ n'ozuzu carbon dioxide gas, na gas eruba ọnụego bụ 20 ~ 25L / min.
3. The kwesịrị ekwesị anya n'etiti ịgbado ọkụ n'ọnụ na workpiece bụ 15 ~ 25mm.
4. Akọrọ ndọtị ogologo, izugbe ịgbado ọkụ ugbu a bụ banyere 15mm mgbe ịgbado ọkụ ugbu a bụ n'okpuru 250A, na banyere 20 ~ 25mm mgbe ịgbado ọkụ ugbu a dị n'elu 250A bụ ihe kwesịrị ekwesị.
