How do I know what amp to weld at?
The specific amperage to be used depends primarily on the diameter of the electrode. For example, an eighth in diameter electrode welds great between 75 and 125 amps. Whereas a 5/32 diameter electrode can weld optimally at up to 220 amps.
What amp should I set my stick welder to?
Answer: A 225 to 300 amp machine handles almost anything the average person will encounter; as most Stick welding procedures require 200 amps or less. To weld material thicker than 3/8 in., simply make multiple passes – this is what professionals do, even when welding on 1 in.
What can you weld with a 70 amp stick welder?
The 70 amp arc welder is best used on thin sheets of metals that are about 1/8th of an inch and 18-gauge thick. Wrought iron, automotive sheets, and boat trailer are just some of the things you can weld with a 70 amp arc welder.
What amp do I need to weld with a 7018 Rod?
Amperage Rule In general, the 7018 rod is used with currents up to 225 amps. A rule of thumb is to use 30 amps of current per 1/32 inch of rod diameter. That would mean using 90 amps of current on a rod that is 3/32-inch in diameter.
Should you push or pull a stick weld?
Push or pull: Here the rule is simple. “If it produces slag, you drag,” says Leisner. In other words, you drag the rod or wire when welding with a stick or flux-core wire welder. Otherwise, you push the wire with metal inert gas (MIG) welding.
How thick can you weld with a stick welder?
The more knowledge and experience you have, the thinner metals you can stick weld. Stick welding gives good results from 1/8″ thick metal and up, but it is not the ideal welding process to weld thinner workpieces. Before you start stick welding projects that involve thin metal, you need more information about it.

What does amperage mean in welding?
Welding cable ampacity, also known as amperage capacity, current capacity, or amp ratings, refers to the maximum amount of electrical current that a cable can safely conduct. Amperage, also known as current, is a measure of the number of charged particles (coulombs) moving past a fixed point in one second.
How many amps does a welder need?
The proper size breaker required for a welder is a 30 AMP. This AMP can be used for many different jobs and tasks that need to be fulfilled by any normal welder.
What are amps and Volts in welding?
In simple electricity terms it’s like the flow of water where amps is the water flow and volts is the pressure of the water . In welding terms amps is the “heat”. To get more weld penetration or to weld thicker diameter material, you turn up the heat/amperage. However, to increase the amps you need to have enough volts.
