I am currently considering purchasing a MIG welder?

1. To learn how to use a MIg welder, already can ARC weld and have a good quality Inverter TIG/Arc welder. Setting it up and learning scares me.

2. Would like to learn MIG welding for body panel work.

I do not envisage heavy duty MIG work, only body panels.

Would like opinions on what would be the max Amprating I would need? DO the ones with digital read outs for voltage and Amps have any advantage over the basic type.

What do I need to look for in features?

Thanks for any advice.

In my opinion an inverter MIG will provide finer adjustment
You aren't going to need anything size wise. A better quality welder is a better quality welder. They just work better. I wouldn't buy anything less than a BOC.

Also look at the quality of the sleeve / wire feed line and the handset.
Keeping in mind you are going to find yourself in funny positions when welding panels. Especially undercarriage. You need something that works well and does not keep getting tangled.
So a good quality welder with lower power but better handle and sleeve will win over a cheaper welder with higher power anyday.
Or factor in getting a decent second hand unit and replacing the inner sleeve and full tip set. That will also give you good usage.

Thanks,

So far that information leads me to judge that a 185 Amp Inverter unit is the minimum type and a 36 torch socket is a must for adaptability.

The local shops all have so called reputable brands with twelve month warranties, each pushing their own wheelbarrow of course.

Is there anything else I should be looking for?

I know this is not important for the use but a nice stand is good too. If you get one of the bug size E bottles they are pretty heavy so it is nice to have then attached to the welder.
But then again, you can always weld yourself up a stand with whatever you want on it too.
